Armpit Skin Peeling: Causes and Treatments

Skin peeling is nature’s design to remove dead skin cells. New skin cells replace the dead ones so that the freshness and suppleness of your skin will be maintained. Skin peeling happens all over our body, even in places where we might not think, like the armpit.

Skin irritations, like peeling, are often experienced in parts of the body where the skin frequently rubs against itself. It also occurs in areas where the skin folds over itself. Your armpit is one such part where chafing or skin peeling occurs.

So armpit skin peeling is quite normal. It is usually caused by skin rubbing against skin. It can also occur when the skin rubs with rough clothing for a long time or if it happens repeatedly.

What Is Armpit Skin Peeling?

When the skin in your armpit excessively peels, it will expose the inner layers of your skin. This peeling will result in new layers to prematurely form.

When this happens, the new skin layers will at first appear reddish. Thereafter, skin peeling will occur. The skin will also be sensitive to touch and exposure to the sun’s rays. You may require treatment to prevent your skin from chronic damage.

Skin peeling is also classified by some dermatologists as underarm rashes. There are at least three types of armpit skin peeling or underarm rashes.

1. Fungal Infection

If your armpit skin peeling is caused by a fungal infection, your underarm skin will have a patchy and itchy rash with an irregular edge. An antifungal cream will be recommended by your doctor to get rid of the infection.

2. Heat Rash

There will be bumps that look like pimples in your armpit. They also tend to itch and burn. Usually, they are the result of perspiration trapped in your armpit. If you use talcum powder, it will absorb the moisture and keep your armpit dry.

3. Intertrigo

This skin condition causes raw and red rashes in your armpit. These rashes develop in the creases of the skin and then spread outward. They are also accompanied by flaking and itching. Intertrigo often occurs when the skin of a moist armpit rubs against itself.

There are other medical conditions or types of armpit skin peeling, but these three skin conditions are the most common. If you have this condition, your medical provider will be able to tell you which type of armpit skin peeling you have.

What Are the Causes of Armpit Skin Peeling?

causes of armpit skin peeling

There are several possible causes of armpit skin peeling.

1. Irritation

If you repeatedly scratch your underarm over a period of time, you may experience armpit skin peeling. Skin irritation from repeated scratching may also cause an infection in your underarm. Your underarm is a good breeding ground for harmful bacteria because it is warm and often moist.

When the skin breaks because of excessive scratching, the risk of developing infection also increases. You can also inflict cuts on your armpit if you are careless in shaving underarm hair.

2. Sunburn

Sunburn will occur if you overexpose your armpit to the rays of the sun. At first, there will be blisters on your skin before armpit skin peeling happens. To prevent skin peeling, you need to use a moisturizer. Using a reliable moisturizer will prevent your skin from being dry and flaky.

3. Eczema

Eczema can also cause armpit skin peeling. This skin condition causes skin inflammation in the folds of the skin. Inflammation is characterized by patches of infected skin, which will appear red, dry, and cracked. They will be itchy and tends to release clear fluid when they are scratched.

4. Contact Dermatitis

Another cause of armpit skin peeling is contact dermatitis. This skin condition arises when the skin gets into contact with an irritant or allergen. You will notice certain symptoms on your skin after a few hours of contact. There will be skin rashes that are reddish, dry, blistered, and itchy.

The most common irritants and allergens are insect bites or stings, food allergens, chemicals in personal care products, cleaning agents, environmental allergens, and medications.

5. Hyperhidrosis

Those who are afflicted with hyperhidrosis are susceptible to armpit skin peeling. This medical condition causes the sweat glands to overwork. It will induce excessive perspiration of the underarms, hands, and feet.

To treat this condition, your dermatologist will recommend the use of a prescription-strength underarm antiperspirant to control excessive sweating.

6. Seborrheic Dermatitis

This skin condition is a type of eczema and one of the causes of armpit skin peeling. It shows up around the oil-producing glands of the body. The symptoms are similar to that of eczema, where the affected skin areas are swollen, reddish, greasy, burning, and itchy. Later, the skin will become flaky and yellowish-white in color.

7. Sweating

If you use natural deodorants, nothing will stop your armpits from sweating because they are not antiperspirants. As a result, your armpit will always be wet and moist. Moreover, the skin on your armpits will be sticky as it rubs against itself. There will be a lot of friction that will result in skin irritation.

After some time, your armpit skin will turn red and feel itchy. This skin condition is called intertrigo. It is the most common cause of armpit skin peeling and underarm rashes.

8. Baking Soda

Adding too much baking soda to a deodorant will also cause armpit skin peeling. High concentrations of baking soda will increase the alkalinity of your deodorant and make your deodorant too abrasive. For this reason, skin rash often develops. Additionally, if your deodorant is sticky, you will be more prone to skin chafing.

9. Allergy

Using a deodorant that you are allergic to will also cause armpit skin peeling. If you suspect that this is the case, try not to use the deodorant for a couple of days and see what happens.

Some deodorants contain aluminum chlorohydrate. This substance could block your skin pores and induce the development of pimples. If the skin rashes stop, then the culprit is probably your deodorant.

Use a hypoallergenic deodorant to reduce the chances of armpit skin peeling. However, if the rashes become worse, you need to consult a dermatologist for proper diagnosis and treatment.
