In the world of skincare, exfoliation is probably one of the most transformative steps… and yet one of the most misunderstood.
Many people think that using a scrub from time to time is enough to achieve radiant skin. In reality, there are now several forms of exfoliation, each with a different mechanism and specific benefits.
When skin becomes dull, texture appears uneven, or skincare seems less effective, the issue often comes from a buildup of dead skin cells on the surface of the epidermis. This invisible layer prevents light from reflecting properly and limits the penetration of active ingredients found in serums and creams.
Well-chosen exfoliation therefore helps reveal a brighter complexion, refine skin texture, and optimize the effectiveness of the entire routine.

Why exfoliation truly changes skin quality
The skin naturally has a cellular renewal mechanism. On average, the epidermis renews itself every 28 to 40 days.
With stress, pollution, UV exposure, or simply skin aging, this process can slow down. Dead skin cells then accumulate on the surface.
Gradually, the complexion becomes duller, skin texture appears less even, and pores seem more visible. Skincare products also penetrate less effectively because they must pass through this layer of dead cells.
Exfoliation helps restart this natural process. It acts like a reset for the skin by removing dead cells that dull the complexion and prevent skincare from working effectively.
The different types of scrubs and peels
Today, three main forms of exfoliation are distinguished:
• mechanical scrub
• enzymatic scrub
• chemical peel
Although their objective is identical — removing dead skin cells — their mechanisms are very different.
Understanding these differences helps you choose the exfoliation best suited to your skin.
Mechanical scrub: traditional exfoliation
Mechanical scrub is the most well-known form of exfoliation.
It contains fine exfoliating particles that remove dead skin cells through massage. When circular movements are performed on the skin, these particles dislodge dead cells from the surface of the epidermis.
Exfoliating particles may be naturally derived, such as fruit seed powders, sugar, or certain mineral powders.
This type of scrub provides immediate results: the skin feels softer, smoother, and the complexion appears brighter. However, it requires gentle application. Excessive pressure can irritate the skin or cause small micro-inflammations.
Gressa Skin’s Renewing Polish is an excellent example of a modern mechanical scrub. It combines exfoliation with nourishing actives to smooth the skin while respecting its balance.
Enzymatic scrub: gentle exfoliation
Enzymatic scrub works according to a completely different principle. Unlike mechanical scrubs, it contains no grains. Its action relies on natural enzymes derived from fruits such as pineapple or papaya.
These enzymes have the ability to dissolve the proteins that hold dead cells together. They therefore detach dead cells from the surface of the skin without the need for friction.
This method exfoliates the skin very gently. Dead cells are removed while the skin remains comfortable and soothed.
This is why enzymatic scrubs are often recommended for sensitive or reactive skin.
Chemical peel: exfoliating with acids
Chemical peels rely on the use of exfoliating acids. These acids dissolve the bonds between dead skin cells and stimulate cellular renewal. Unlike mechanical scrubs, exfoliation occurs at the molecular level.
This form of exfoliation works uniformly across the entire surface of the skin and can be particularly effective for improving radiance and skin texture.

AHA: to revive skin radiance
AHA, or Alpha Hydroxy Acids, are water-soluble fruit acids.
They work mainly on the surface of the skin by stimulating cellular renewal and improving radiance.
AHAs are often used to improve skin texture, reduce certain pigmentation spots, and smooth early fine lines.

BHA: to purify pores
BHA are oil-soluble acids, meaning they mix with sebum and can penetrate pores. Salicylic acid is the best-known BHA. It helps dissolve sebum and unclog pores.
It is particularly beneficial for oily or blemish-prone skin as it helps improve the appearance of blackheads and enlarged pores.

PHA: next-generation exfoliation
PHA represent a gentler generation of exfoliating acids.
Their larger molecular structure allows progressive, less irritating exfoliation. They exfoliate while helping maintain hydration.
PHA are therefore particularly suited for sensitive or dehydrated skin.
Which exfoliant to choose according to your skin type?
Not all forms of exfoliation have the same impact on the skin. Choosing the right method helps achieve better results while respecting the skin barrier.
Sensitive skin
Sensitive skin requires very gentle exfoliation. Enzymatic scrubs or PHA acids are generally best tolerated because they exfoliate without friction.
Dry skin
Dry skin often benefits from AHAs such as lactic acid, which exfoliates while improving hydration.
Oily skin
BHA are particularly suited to oily skin because they penetrate pores and dissolve excess sebum.
Dull or mature skin
AHAs can help stimulate cellular renewal and revive radiance.
Most common exfoliation mistakes
Exfoliation is a powerful step to improve skin quality, but certain mistakes can cause the opposite effect.
Exfoliating too often
Excessive exfoliation can weaken the skin barrier and make the skin more sensitive.
Mixing too many exfoliants
Using several exfoliants at the same time can cause irritation. It is better to introduce actives gradually.
Neglecting hydration
After exfoliation, the skin needs to be soothed and hydrated to maintain its balance.
Forgetting sun protection
Exfoliants make the skin more sensitive to UV exposure. A sun protection is therefore essential.
