As the pillars of the human body, feet are often neglected despite requiring 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!
Why should you do a foot peeling mask?

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, thus destabilising the horny layer and causing its progressive detachment.
Generally, a chemical peel involves substances known as 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 prime choice for areas such as the feet, which are prone to colonisation 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 characterised?
The skin on the soles of the feet is significantly thicker as the cells divide more frequently in response to pressure and friction. This is a physiological response aimed at strengthening 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 typical 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 frequent excessive sweating in this part of the body.
Why should you do a peeling foot mask?
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 hard skin that regularly appears on the feet, particularly on the heel. From an aesthetic point of view, smooth feet are often much more appreciated.
Sometimes enriched with moisturising 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 generally dry or even very dry due to the absence of sebaceous glands.
In the market, peeling masks are typically available in the form of exfoliating socks. The principle 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 necessary to rinse your feet with warm water. This type of treatment is carried out once or twice a month.
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.
