Desquamation refers to pieces of skin that come off, in a normal or pathological way. Usually mild, peeling may be associated with more troublesome disease. Also, it is important to consult a doctor if in doubt.

Desquamation refers to the normal or pathological elimination of the horny layer (also called stratum corneum) of the skin, i.e. the outer layer of the epidermis (itself the outer layer of the skin). It can affect all areas of the body, such as the eyebrows, skull, face or even the feet. For example, when the scalp is peeling because the desquamation is abnormal (in this case, excessive), we speak of dandruff.

The ends, lamellae, or flakes of skin that come off are referred to as scales.

Remember that the skin is the largest and heaviest organ in the human body. It has several crucial roles and in particular the protection of the organism against harmful elements of the environment (such as wind, heat, drought, humidity, germs, etc.), hormonal synthesis, or even a function hormonal.

The peeling may be accompanied by other symptoms, such as itching or dryness of the skin.

Skin cells (called epithelial cells) from the stratum corneum are constantly detached, and are replaced by new cells that grow back.

But peeling can occur as a result of direct damage to the skin, be a sign of an immune system disorder or some other disease. Thus, in addition to simple dry skin, there are many factors that can be the cause of abnormal or pathological peeling. Let us quote for example:

• a sunburn ;
• the use of detergents;
• an allergy ;
• contact dermatitis (which can be irritating or allergic);
• eczema;
• vitamin deficiency;
• an inflammatory disease, such as psoriasis (in those affected, the skin cells are renewed every 3 to 6 days, compared to 28 to 30 days normally);
• an infectious disease, such as measles, rubella or scarlet fever;
• a fungal infection, such as athlete’s foot;
• or in more rare cases, skin cancer.

If the desquamation is not taken care of, it can in some cases lead to itching, which in turn can cause lesions or localized infection.

Unsightly, even embarrassing, desquamation can cause the person who suffers to withdraw into oneself.

In many cases, such as after sunburn, peeling does not require medical attention. Applying a suitable moisturizer and soothing cream is a good solution.

On the other hand, if the symptom is severe, that it lasts or that the cause is not identified, then it is advisable to go to see a doctor before trying to take a medication or to apply a cream which would not be. not adapted.

The doctor (dermatologist) will suggest treatment depending on the cause of the peeling:

• an antifungal for a fungal infection;
• an emollient or moisturizer, or corticosteroids for psoriasis;
• taking vitamins in the event of a specific vitamin deficiency;
• anti-dandruff shampoo (containing tar or zinc ink) in case of excessive scalp scalp;
• or taking antihistamines in the case of an allergy.
