Peeling skin, or desquamation, refers to the loss of skin clusters, known as scales. This process involves the removal of the horny layer, the upper layer of the epidermis. On average, skin cells renew themselves every 28 days. Therefore, desquamation is a normal phenomenon but can become pathological when it occurs too frequently.
Typically, peeling skin is a sign of dehydration. When the skin is healthy, it maintains a balance between water and lipids. However, in the event of external aggressions or skin dryness, this balance is disrupted, making the skin sensitive and vulnerable. Consequently, lipid production decreases, preventing the skin from naturally maintaining its hydration and protection. To restore this balance, cellular regeneration is accelerated, hence the peeling.
Desquamation can affect all parts of the body such as the face, eyebrows, feet, or even the hands. In the scalp, it is the cause of dandruff. This phenomenon can be accompanied by other symptoms such as itching.
