Glycolic acid is made up of the smallest molecules in the alpha-hydroxy acid (AHA) category, making it one of the most impactful when it comes to skin care because it can more easily penetrate the skin. It is also surprisingly natural as it is derived from sugar cane. It is recognised and beloved by dermatologists for its resurfacing and smoothing properties. It has skin exfoliating benefits to help shed dead cells that accumulate on the surface of the skin, and helps brighten a dull complexion, enhance radiance, and improve skin tone. Glycolic acid also helps improve the appearance of fine lines and wrinkles.


NEW Glyconight 10% Masque by Yon-Ka Paris is a Smoothing Peel Mask, That Gives Skin renewal & Radiance. With 10% glycolic acid, this product buffs away dead skin cells and fades dark spots—but without any drying or peeling. It is one of the rare chemical exfoliators that is both advanced strength and gentle enough for every other day use. Inspired by the chemical peel, this night mask is formulated so you can perform a noticeably effective and excellently tolerated peel at home.


A night peeling mask with 10% pure glycolic acid

Effective immediately, and even more effective over time

Smoothing, skin renewal, radiance.

With dual action (peeling and anti-aging) properties, Glyconight 10% Mask gives a multifaceted appeal. It is suitable for both men and women.

This mask sloughs away dead skin cells, drastically improving the skin’s quality and texture. Pores are tighter and the depth of the wrinkles and fine lines is visibly reduced. The morning after you apply the mask, your complexion looks more radiant and even. Wrinkles are visibly smoothed away; skin is denser, much softer, more beautiful, and younger-looking*.

At night, after removing makeup and cleansing, apply a thin layer of the mask to the face and neck. Leave on all night. Rinse off with tepid water the next morning.
