What May Happen To The Skin If An Area Is Subject To Pressure Or Friction

Understanding Pressure and Friction on Skin

What is pressure and friction?

Pressure is the force applied perpendicular to the surface of an object per unit area. When your skin experiences pressure, the force presses down on it, compressing the tissue underneath. Common sources of pressure on the skin include:

Body weight pressing down on skin when sitting or lying in one position for extended periods
Tight shoes or clothing squeezing the skin
Carrying heavy bags that dig into the shoulders or hands
Medical devices like casts, braces, or oxygen masks resting on the skin

Friction is the resistance that occurs when two surfaces rub against each other. Friction can be beneficial, like when it allows you to grip objects securely. However, when friction is excessive or repetitive, it can irritate and damage the skin. Common sources of friction include:

Skin rubbing against clothing or bedding
Body parts rubbing together, like the inner thighs or underarms
Poorly fitting shoes sliding back and forth against the feet
Sporting equipment like helmets or pads chafing the skin

How do pressure and friction affect the skin?

To understand how pressure and friction impact the skin, it’s helpful to know a bit about skin anatomy. Your skin is composed of three main layers:

Epidermis: The outermost layer of the skin, the epidermis provides a waterproof barrier and creates our skin tone. The epidermis contains several layers, with the topmost layer consisting of dead cells that regularly shed and get replaced by new cells.
Dermis: Beneath the epidermis, the dermis contains tough connective tissue, hair follicles, and sweat glands. The dermis provides strength and elasticity to the skin through a network of collagen and elastin fibers.
Hypodermis: The deeper subcutaneous tissue, the hypodermis is made of fat and connective tissue that insulates the body and provides a cushion between skin and bone.

When pressure or friction is applied to the skin, these layers can be affected in different ways:

The epidermis may thicken in response to repeated pressure or friction as the body attempts to protect the underlying tissue. You’ve probably noticed this on your own feet – areas that experience a lot of rubbing, like the heel or ball of the foot, often have thicker, tougher skin than other areas.
Over time, excessive pressure or friction can cause the epidermis to break down, creating sores or blisters. If pressure isn’t relieved, these wounds can extend more deeply into the dermis and even the hypodermis.
Pressure and friction can also compress the blood vessels in the dermis and hypodermis, decreasing blood flow to the area. Without sufficient blood supply, the tissue can’t receive the oxygen and nutrients it needs to stay healthy, causing the skin to become inflamed, starved of nourishment, and eventually die.

Common Signs of Skin Irritation from Pressure and Friction

Knowing the warning signs of skin damage from pressure and friction is key to catching problems early. Here are some of the most common indicators that your skin is being irritated:

Redness (Erythema)

One of the earliest signs that your skin is experiencing too much pressure or friction is a change in color. The affected area may turn pink or red as blood vessels in the dermis dilate in response to the irritation. This redness is called erythema. According to Dr. Cynthia Bailey, a board-certified dermatologist, “Dermatologists often advise checking for redness as an early sign of friction irritation.”

Erythema can occur with even short periods of friction, like a long walk in poorly fitting shoes leading to red, raw spots on your feet. The redness should disappear not long after the pressure or friction stops. However, if the redness persists or worsens, it can indicate more serious skin damage.

Blisters (Fluid-filled pockets)

Blisters are a common consequence of repeated friction on the skin, especially on the hands and feet. These small, fluid-filled bubbles form when the uppermost layer of the epidermis separates from the layers below and the space between fills with a clear liquid called serum. Blisters act as a cushion to protect the raw, damaged skin underneath as it heals.

While most blisters are more annoying than dangerous, they can become a problem if they break open. “Blisters can be painful and may become infected if not cared for properly,” warns Dr. Adnan Nasir, a dermatology professor at UC Davis. Avoid picking or popping blisters to reduce the risk of infection. If a blister does rupture, gently clean the area and apply an antibiotic ointment and bandage to protect the healing skin.

Calluses (Thickened skin)

In areas that regularly experience pressure or friction, like the feet or fingertips, the skin may thicken and harden into calluses. These rough, yellowish patches of skin are actually the body’s way of defending the deeper layers. “Calluses are the body’s natural way of protecting itself from repeated pressure and friction,” explains Dr. Suzanne Friedler, a dermatologist in New York City.

Calluses are generally harmless, but very thick or extensive callusing can become painful. Severe calluses may crack, allowing bacteria to enter and potentially cause infections. Regularly exfoliating and moisturizing callused skin can help keep it supple and prevent painful splitting.

Cracking (Breaks in the skin)

Repeated friction or pressure can cause already dry or thickened skin to crack and fissure. These tears in the skin usually affect the heels, fingers, elbows, or knees. Cracks can be shallow or deep, and some may even bleed. According to Dr. Shari Lipner, a dermatologist at Weill Cornell Medicine, “Cracked skin can be painful and increase the risk of infection.”

To prevent skin cracking, keep the skin moisturized with thick, fragrance-free creams or ointments. Avoid harsh soaps that can further dry out the skin. If cracks are deep or bleeding, wash them gently with soap and water, apply an antibiotic cream, and cover with a clean bandage until healed. See a doctor if the cracks are severe or showing signs of infection.

Causes of Skin Problems from Pressure and Friction

Many different factors can subject your skin to excessive pressure or friction. Some of the most common causes include:

Improper footwear

One of the biggest culprits behind friction-related skin problems is poorly fitting or inappropriate shoes. Shoes that are too tight put pressure on the feet and don’t allow the skin to breathe. Shoes that are too loose cause the feet to slide and rub. High heels and thin-soled shoes can also put extra pressure on certain areas of the feet.

“Shoes that are too tight or lack proper support can cause pressure and friction on the feet,” notes Dr. Christina Long, a podiatrist in North Carolina. Blisters, calluses, corns, and cracked heels can all result from improper footwear. Choosing shoes that fit well, provide cushioning, and allow space for your toes can help minimize friction.

Repetitive activities

Repeated motions put stress on the same areas of skin over and over, leading to friction and irritation. This is especially common in certain occupations or sports. For example:

Construction workers may develop rough, thickened skin on their hands from using tools all day
Cyclists may experience chafing and blisters on their inner thighs and buttocks from their bike seats
Gymnasts and weightlifters often get calluses on their palms from gripping
Musicians and athletes may develop calluses on their fingers from playing instruments or gripping equipment. Finding ways to cushion the skin can help prevent excessive callus buildup.

Medical conditions

Certain health issues can make you more susceptible to skin problems from pressure and friction. “Conditions like diabetes or obesity can increase the risk of pressure sores,” explains Dr. Alisha Plotner, a dermatologist at The Ohio State University Wexner Medical Center.

People with diabetes often have reduced circulation and nerve function, so they may not feel when pressure is causing damage. Obesity puts extra weight on pressure points, increasing the risk of skin breakdown. Individuals with paralysis or loss of sensation are also vulnerable since they can’t feel when their skin is being irritated.

Poor posture

How you sit and stand can affect where your skin experiences the most pressure. “Slouching can put uneven pressure on your back and shoulders,” says Dr. Fredrick Wilson, an orthopedic surgeon in California. Hunching over a desk or slouching in a chair can cause areas of high pressure where your bones push against your skin. Over time, this can lead to skin irritation and even pressure sores in severe cases. Maintaining good posture helps distribute your weight more evenly.

Ill-fitting clothing

Clothing that is too tight puts constant pressure on your skin, while clothing that is too loose can rub and chafe. “Tight clothing can rub against the skin, causing irritation,” notes Dr. Ife Rodney, a dermatologist in Maryland. Common areas chafed by clothing include the thighs, groin, underarms, and nipples. Choosing breathable, moisture-wicking fabrics and ensuring a proper fit can minimize friction from clothing.

Environmental factors

Hot, humid weather can make skin irritation from friction worse. “Hot and humid climates can increase sweating and friction,” says Dr. Lola Priego, a dermatologist in the Philippines. Wet skin is more prone to chafing, and excessive sweating can make skin problems like athlete’s foot fungus more likely. Staying cool, dry, and using anti-chafing products can be especially important in warm environments.

Who is Most at Risk of Skin Problems from Pressure and Friction?

While anyone can experience the effects of pressure and friction on their skin, some people are at higher risk than others. Those most prone to skin problems include:

People with diabetes or poor circulation

Diabetes can cause nerve damage and reduced blood flow, making it harder for the skin to heal from pressure and friction. “People with diabetes are at high risk of developing pressure sores,” warns Dr. Ernie Tannis, a dermatologist in Toronto. Poor circulation from any cause decreases the skin’s ability to tolerate pressure and friction.

Individuals with physically demanding jobs

Jobs that involve a lot of walking, standing, or lifting put increased stress on the skin. “Construction workers, nurses, and factory workers are prone to calluses and blisters,” notes Dr. Donna Bilu Martin, a dermatologist in Florida. Wearing proper footwear and gloves, taking breaks, and promptly treating any irritation can reduce the risk of job-related skin problems.

Athletes engaged in repetitive activities

Many sports involve repeated motions or prolonged pressure on the skin. Runners are prone to blisters, cyclists to saddle sores, and gymnasts to hand rips. “Athletes need to be especially vigilant about preventing and treating skin injuries,” advises Dr. Brian Adams, a sports medicine physician in Illinois. Well-fitting equipment, protective gear, and skin lubricants can help minimize skin damage.

People who are overweight or obese

Extra body weight puts more pressure on the skin, especially in areas like the feet, groin, and underarms. “Obesity is a major risk factor for pressure sores,” states Dr. Rajeev Venkayya, president of the Global Vaccine Business Unit at Takeda Pharmaceuticals. Maintaining a healthy weight through diet and exercise can reduce pressure on the skin. Keeping skin folds clean and dry is also important.

Those with limited mobility or loss of sensation in limbs

People who use wheelchairs or are bedridden are at high risk of pressure sores. Spinal cord injuries, paralysis, and nerve damage from conditions like multiple sclerosis can cause loss of sensation, so the skin doesn’t signal when damage is occurring. “Frequent repositioning and pressure-relieving cushions are crucial for preventing pressure sores in people with limited mobility,” says Dr. Jill Stein, a physical medicine and rehabilitation specialist in Washington.

Preventing Skin Irritation from Pressure and Friction

While it’s impossible to completely avoid pressure and friction on your skin, there are many ways to minimize their impact. Incorporating these preventive strategies can help keep your skin healthy:

Wear proper fitting clothing and shoes

One of the best ways to reduce friction is by choosing clothes and shoes that fit well. “A good fit can significantly reduce pressure and friction,” advises Dr. Shilpi Khetarpal, a dermatologist at the Cleveland Clinic. Make sure your shoes have adequate room in the toe box and don’t rub or pinch anywhere. Avoid clothing that is too tight or too loose. Seamless socks and moisture-wicking fabrics can also help.

Take breaks during activities

Giving your skin a chance to rest and recover can prevent irritation from building up. “Allow your skin to breathe and recover from repetitive stress,” recommends Dr. Latanya Benjamin, a dermatologist in Florida. If you have to stand a lot at work, take sitting breaks. Athletes should build in rest days and avoid training the same body parts on consecutive days. Periodically relieving pressure on the skin allows it to bounce back.

Maintain a healthy weight

Carrying extra pounds puts more strain on pressure points like the feet, increasing the risk of skin breakdown. “Excess weight puts extra pressure on your feet and other pressure points,” warns Dr. Shari Lipner, a dermatologist at Weill Cornell Medicine. Losing weight if needed can significantly reduce pressure on the skin. Even small changes can make a difference.

Practice good posture

Slouching and poor alignment can cause uneven pressure on the skin. “Proper posture distributes weight evenly and reduces pressure on specific areas,” explains Dr. Karena Wu, a physical therapist in New York. Be mindful of your posture when sitting, standing, and exercising. Keep your spine straight and your shoulders back. Use ergonomic chairs and workstations when possible to promote healthy alignment.

Use padding or lubricants

Putting a barrier between your skin and sources of friction can prevent irritation. “Gels, creams, or bandages can help reduce friction,” suggests Dr. Tsippora Shainhouse, a dermatologist in Los Angeles. Apply a chafing cream or petroleum jelly to areas prone to rubbing, like the inner thighs or underarms. Specialized padding and bandages can cushion pressure points to avoid skin breakdown.

Keep skin moisturized

Dry skin is more vulnerable to damage from friction. “Moisturized skin is more flexible and less prone to irritation,” notes Dr. Joshua Zeichner, a dermatologist in New York City. Use a thick, fragrance-free moisturizer on areas that experience a lot of pressure or rubbing. Applying the moisturizer to slightly damp skin can help lock in hydration. Don’t forget to moisturize your feet daily.

Inspect skin regularly

Catching skin irritation early allows you to make changes before a larger problem develops. “Early detection of any signs of irritation allows for prompt intervention,” advises Dr. Rajani Katta, a dermatologist in Texas. Make a habit of checking your skin daily, especially in areas prone to pressure or friction. Look for redness, blisters, calluses, or cracks. Address any issues immediately to prevent them from worsening.

Treating Skin Problems Caused by Pressure and Friction

Despite your best prevention efforts, your skin may still sometimes fall victim to pressure and friction. If you notice any signs of skin damage, don’t ignore it. Treating skin issues promptly can help speed healing and avoid complications. Treatment options include:

Over-the-counter creams and ointments

Many skin irritations can benefit from topical treatments you can buy without a prescription. “These can help soothe irritation and promote healing,” says Dr. Debra Jaliman, a dermatologist in New York City. Ingredients to look for include:

Petroleum jelly to reduce friction
Aloe vera to calm inflammation
Ceramides to improve skin barrier function
Hydrocortisone cream to relieve itching and redness

Use as directed and discontinue if irritation worsens or doesn’t improve.

Protective dressings for blisters

Blisters heal best when kept clean and covered. “Maintain a sterile environment and prevent further damage,” advises Dr. Adnan Nasir, a dermatology professor at UC Davis. If a blister is small and unbroken, leave it alone and cover with a loose bandage to prevent further irritation. Larger blisters or those on pressure points may need to be drained. “If you have to drain a blister, do so with a sterile technique to avoid infection,” advises Dr. Rajani Katta. Wash your hands, use a clean needle to make a small hole at the blister’s edge, and gently squeeze out the fluid. Apply antibiotic ointment and cover with a non-stick bandage.

Debridement for pressure sores

Pressure sores that are severe or not healing may require debridement, which is the removal of dead tissue to allow healthy tissue to grow. “Debridement is often necessary for stage 3 or 4 pressure sores,” explains Dr. Jeffrey Niezgoda, president of the American College of Hyperbaric Medicine. Debridement can be done using enzymes, wet-to-dry dressings, or surgery in extreme cases. This should only be done by a medical professional to avoid causing further damage.

Prescription medications

If skin damage becomes infected, oral or topical antibiotics may be necessary. “Infections can spread quickly, so prompt treatment is crucial,” warns Dr. Adam Friedman, a professor of dermatology at George Washington School of Medicine. Severe pain from pressure sores may also require prescription pain relievers. Follow your doctor’s instructions carefully and take the full course of antibiotics even if symptoms improve.

When to See a Doctor for Skin Problems

While many minor skin irritations from pressure and friction can be managed at home, some require medical attention. See your doctor promptly if:

Pain, redness, or swelling persists for several days despite home treatment. “Lingering symptoms can indicate a more serious problem,” advises Dr. Sarina Elmariah, a dermatologist at Massachusetts General Hospital.
Blisters become infected, indicated by increasing pain, redness, swelling, warmth, pus drainage, red streaks, or fever. “Infected blisters need professional treatment to avoid complications,” says Dr. Tsippora Shainhouse.
Pressure sores develop, especially on deep tissues like muscles or bones. “Deep pressure sores can cause severe complications and need immediate care,” warns Dr. Jill Stein. Look for signs like non-blanching redness, blisters, open sores, or skin that feels cooler or firmer than surrounding areas.
There is a loss of sensation in the affected area, which can indicate nerve damage. “Numbness or tingling can be a sign of serious injury,” notes Dr. Rajani Katta. This is more likely in people with diabetes or spinal cord injuries.

How long does it take for skin to heal from pressure and friction?

Healing time depends on the severity of the skin damage. Minor irritation or redness usually resolves within a few days with proper care. Blisters typically take 3-7 days to heal and dry up on their own. Calluses may peel off after a few days but will likely recur if the causative friction continues. Pressure sores can take days to months to fully heal depending on the depth of tissue damage and the individual’s overall health. “Superficial pressure sores usually heal within a few weeks, while deep wounds can take several months and are more prone to complications,” explains Dr. Jeffrey Niezgoda.

FAQs

Can I prevent calluses from forming?

While calluses are a natural defense mechanism, you can minimize their formation with proper prevention techniques. Keep skin moisturized, wear gloves when using tools, and make sure your shoes fit properly. Pressure-relieving insoles and regular exfoliation can also help. However, don’t try to remove calluses by cutting or shaving them off, as this can cause injury and infection.

What’s the best way to treat a blister?

For small, unbroken blisters, leave the skin intact to protect against bacteria. Cover with a loose bandage or dressing to prevent further irritation. If a blister is large, painful, or interferes with movement, it may need to be drained. Wash your hands, disinfect a needle, puncture the edge of the blister, and gently squeeze out the fluid. Apply antibiotic ointment and a non-stick bandage. Seek medical care if the blister is infected or not healing.

How do I know if I have a pressure sore?

Pressure sores often appear as areas of persistent redness that don’t lighten when pressed. The skin may feel warmer, cooler, firmer, or softer than surrounding tissue. In later stages, blisters, open sores, or deep craters exposing underlying fat, muscle, or bone may develop. Consult a doctor immediately if you suspect a pressure sore, especially in someone with limited mobility or sensation. Early diagnosis and treatment are key to preventing complications.

Are there any long-term complications from pressure sores?

Yes, untreated pressure sores can lead to severe complications. Infections like cellulitis, bone and joint infections, and sepsis can occur and may be life-threatening. Pressure sores can also cause permanent tissue damage, scarring, and muscle or nerve injury. In extreme cases, surgical interventions like skin grafts or even amputation may be necessary. That’s why prevention and prompt treatment are so crucial.

Additional Tips for Athletes and People with Active Lifestyles

If you’re prone to skin irritation from pressure and friction due to athletics or an on-the-go lifestyle, these extra tips can help keep your skin healthy:

Use moisture-wicking clothing to pull sweat away from your skin and reduce chafing. Look for breathable synthetic fabrics and avoid cotton, which traps moisture.
Apply anti-chafing products like balms, creams, or powders to areas prone to rubbing, such as the inner thighs, underarms, and nipples. Reapply as needed, especially in hot weather or during long workouts.
Wear properly fitting sports bras to minimize friction from straps and seams. Choose seamless, moisture-wicking styles and get fitted to ensure the right size and support level for your activity.
Change out of sweaty clothes promptly after exercise to prevent the moist environment from irritating your skin. If you can’t shower right away, use cleansing wipes to freshen up and remove sweat and bacteria.
Consider blister-prevention products like tapes, pads, or special socks if you’re prone to foot blisters. These can provide targeted cushioning and reduce friction in blister-prone areas. Be sure to test them out before a long race or event.
