As fundamental pillars of the human body, feet are often neglected even though they require special attention. In this area, the skin is particularly thick due to friction and contact with the ground. Dead cells form a "callus", which can sometimes be difficult to remove. A peeling mask is then the solution!

Peeling Mask: What is it?
As its name suggests, this type of treatment is to be left on for a few minutes like a mask and exfoliates the skin like a peel.The term peel refers to the action of peeling. It is actually aboutexfoliating theupper layers of the epidermis,in order to promote cellular renewal.
Peeling differs from scrubbing in its mode of action. Scrubbing is a mechanical exfoliation that removes dead skin cells from the epidermis through friction. Peeling, on the other hand, is a chemical exfoliation that eliminates dead cells (keratinocytes) by breaking the ionic bonds, thereby destabilizing the horny layer and causing its gradual detachment.
Generally, a chemical peel involves substances called AHA (alpha hydroxy acid), BHA (beta hydroxy acid) or PHA (poly hydroxy acid).
The most common AHAs are theglycolic acidand thelactic acid. Glycolic acid, being smaller in size than lactic acid, penetrates deeper into the epidermis, hence its greater potential for irritation. For this reason, chemical peels based on lactic acid are generally recommended for sensitive skin.
The most common BHA in cosmetics is thesalicylic acid. Its antibacterial properties make it a preferred choice for areas like the feet, which are prone to colonization by pathogenic microorganisms.
With a larger molecular size than A.H.A. and B.H.A., the P.H.A. (gluconolactone, galactose, lactobionic acid...) penetrate less deeply into the epidermis. Therefore, they are more commonly found in facial care products rather than foot peels, as their penetrating power is not intense enough for the skin of the feet.
How is the skin of the feet characterized?
The skin on the soles of the feet is much thicker because the cells divide more frequently in response to pressure and friction. This is a physiological response that strengthens the protective barrier. However, excessive pressure or friction can trigger an over-thickening, leading to the formation of problematic hard skin or a callus.
Calluses are also generated by a severe dryness that is characteristic of this area. Indeed, the sole of the foot is devoid of hair and therefore of sebaceous glands (glands that secrete sebum). However, the skin located beneath the feet has a much higher concentration of sweat glands than any other part of the body - hence the frequent excessive sweating in this part of the body.
Why should you do a peeling mask for your feet?
Often composed of fruit acids (enzymatic exfoliants) and/or A.H.A. and B.H.A., the peeling mask is used to remove the unsightly callus that regularly appears on the feet, especially on the heel. From an aesthetic point of view, smooth feet are often much more appreciated.
Sometimes enriched with moisturizing agents such as aloe vera gel or lipid-replenishing substances like squalane or ceramides, it can also provide hydration and nourishment to the skin on the soles of the feet, which is typically dry or even very dry due to the absence of sebaceous glands.
In the market, peeling masks typically come in the form of exfoliating socks. The concept is straightforward, you simply need to put on the socks (your feet should be clean and dry beforehand) and keep them on for a certain period (usually at least an hour, sometimes overnight). Upon removing the socks, it is then appropriate to rinse your feet with warm water. This type of treatment is performed once or twice a week.
Tip : To remove the hard skin from your feet, you can supplement the peeling mask with the use of a pumice stone, after each shower. You will regain soft feet.
