Offers a new approach to corneotherapy (corneotherapy, from the Latin corneum = horny layer, is a new field in cosmetics that focuses specifically on the outermost layer of the skin. Cosmopharmacy is a specialised combination of cosmetology and pharmacy). This active ingredient is specially designed to provide gradual, controlled diffusion of AHA acids. The lamellar gel formulation also prevents potential skin irritation or inflammation. The water-based lamellar gel consists of a biomaterial into which AHA acids are absorbed. This technology allows lower concentrations of AHA acids to be used, with effects comparable to those of conventional AHA acids. This makes it suitable even for sensitive skin or skin that becomes irritated or inflamed when conventional AHA acids are used. Composition: a synergy of alpha-hydroxy acids: 15% glycolic acid, 7% lactic acid and 6% citric acid absorbed into a lamellar biomaterial. IN VIVO tests showed renewal of the skin's horny layer, giving the skin a beautiful, more radiant and velvety appearance. AHA acids weaken the cohesion of the stratum corneum (the outermost layer of skin, made up of dead cells called corneocytes), increasing exfoliation and accelerating cell renewal. Effective exfoliation without potential irritation or inflammation of the corneocytes ensures an even skin tone, reduces hyperpigmentation, softens acne scars and releases sebum from the pores.

The mechanism of action involves gradual exfoliation, in which AHA acids weaken the bonds between corneocytes in the stratum corneum, encouraging the shedding of dead cells and accelerating skin renewal. At the same time, the lamellar gel ensures controlled diffusion, minimises irritation and restores the skin barrier. It provides a moisturising effect thanks to lactic acid, antioxidant protection through citric acid and the soothing properties of the biomaterial. The recommended concentration in the finished product is 1-5% for optimal results without the risk of irritation.

Recommended for dry, sensitive, oily, acne-prone, dehydrated and mature skin. Ideal for people with hyperpigmentation, acne scars or an uneven skin tone, for whom conventional AHAs are unsuitable because of irritation. Also suitable for sensitive skin, as lower concentrations achieve comparable effects with less risk.

A study published in the Journal of Cosmetic Dermatology (2004) demonstrated that a combination of 8% glycolic acid and 3% lactic acid in a lamellar system reduced the thickness of the stratum corneum by 25% after 4 weeks, with no erythema occurring in 92% of participants with sensitive skin. Another clinical study in the International Journal of Cosmetic Science (2018) reports that a 5% AHA complex in a biomaterial improved hydration by 40% and reduced hyperpigmentation by 30% over 6 weeks in patients with photoageing.
