Pyruvic acid is an α-keto acid present in honey, vinegar, apples and fermented fruits that presents both epidermal and dermal effects. It is included in the group of medium-depth peels.

At epidermal level md:peel pyruvic 40% + lactic 10% has keratolytic, antimicrobial and sebostatic properties, being very effective in acne treatment. It diminishes the cohesion of epidermal keratinocytes, facilitating desquamation and preventing the thickening of the upper layers of the epidermis.

At dermal level, it has the ability to stimulate new collagen production and the formation of elastic fibers and glycoproteins, reducing wrinkles, photo ageing and hyperpigmentation. A true dermal remodelling is produced, reducing flaccidity and improving skin texture.

Because of its low pka and its small molecular size, it penetrates rapidly and deeply into the skin, rendering very effective results.

Lactic acid strengthens skin barrier function preventing water loss and promoting high skin hydration. It allows an exfoliation without high levels of dryness, thanks to the protective film that forms. Lactic acid increases the production of dermal components, especially Hyaluronic acid, improving skin texture, smoothness, diminishing the appearance of fine lines, sun damage and premature skin ageing.
