* Desquamation: This is the general medical term for the shedding of the outermost layer of skin (the stratum corneum). It's a normal process that occurs constantly.
* Peeling: This term is used when larger flakes or sheets of skin come off, often after a sunburn or chemical peel.
* Exfoliation: This refers to the intentional removal of dead skin cells, usually for cosmetic purposes, using scrubs, chemicals, or tools.
* Sloughing: This term is often used to describe the natural shedding of dead skin cells.
The underlying causes can vary, including:
* Sunburn: Damage from UV radiation causes skin cells to die and peel off.
* Dry skin: Lack of moisture can lead to flaking and scaling.
* Skin conditions: Eczema, psoriasis, and ichthyosis can cause excessive skin shedding.
* Infections: Fungal or bacterial infections can lead to skin peeling.
* Allergic reactions: Contact dermatitis can cause skin to peel and blister.
* Chemical peels or other cosmetic treatments: These procedures intentionally remove layers of skin.
* Medications: Some medications can cause skin peeling as a side effect.
