L71 - Mask Set for Enlarged Pores and Blackheads
10% AHA + 10% PHA

Use this mask one to two times per week — evening only — on clean, dry skin.

Apply a generous layer of the mask to the face using the silicone applicator brush, avoiding the eye contour area. Leave for 10 minutes, then rinse off with clear water.

This mask contains alphahydroxy acid (AHA) which can sensitize your skin to the sun and increase the risk of sunburn. Use sunscreen and limit sun exposure while using this product, and for one week after use.

Not safe for those who are pregnant or breastfeeding. Avoid contact with eyes. In case of contact, rinse thoroughly with clear water.

AHA complex 10%:
A combination of four AHAs (alpha hydroxy acids) of different molecular sizes, allowing them to penetrate more or less deeply into the superficial layers of the epidermis. Their exfoliating action helps renew the skin’s surface, reduce blackheads, and tighten pores.

From the smallest to the largest molecule, this complex includes:

• 7% Glycolic Acid (76 g/mol) :
  The smallest of the AHAs, glycolic acid penetrates the stratum corneum quickly and easily. This deep action provides intense exfoliation, promoting accelerated cell renewal.

• 1.5% Lactic Acid (90 g/mol) :
  Slightly larger, it has the same properties as glycolic acid but with more moderate penetration, offering gentle, gradual, and better-tolerated exfoliation. Its unique feature is its humectant power, which improves skin hydration and strengthens the skin barrier.

• 0.5% Tartaric Acid (150 g/mol) :
  With a higher molecular weight, tartaric acid has limited penetration and acts primarily on the skin’s surface. This results in gentler, more superficial exfoliation. It also plays a role as a pH regulator, optimizing the effectiveness of the other AHAs.

• 1% Mandelic Acid (152 g/mol) :
  The largest molecule, it penetrates the skin more slowly, ensuring good tolerance even for sensitive skin. When combined with other AHAs, it enhances exfoliating action while reducing the risk of irritation or post-inflammatory hyperpigmentation.

Gluconolactone 10%:
This active ingredient from the PHA (poly-hydroxy-acid) family is a gentle chemical exfoliant. It stimulates the natural hydration of the skin while ensuring a micro-exfoliation complementary to the action of the AHA.
