Key Ingredients
Zinc Extract: Zinc is one of the body’s essential trace elements. It is involved in many synthesis processes (nucleic acids, proteins) and plays an important part in cellular differentiation, which means that it has healing properties. It also has astringent and antimicrobial properties. Owing to its inhibiting effect on 5 α-reductase, it reduces sebum secretion, thus purifying and regulating oily skin and mattifying the complexion. It is also used in treatments for oily hair. Zinc is used in combination with L-PCA, which is naturally present in the skin and able to bond to an active molecule and thus become its vehicle. This combination improves the zinc’s bioavailability and effectiveness.
Salicylic Acid (BHA): Salicylic acid is a BHA naturally synthesized by certain plants such as the willow. It is a keratolytic agent that helps eliminate dead cells by breaking bonds between horny layer cells in the epidermis and by causing these cells to be superficially exfoliated without leaving cell waste. The skin is smoother and softer. Salicylic acid also has purifying properties to smooth imperfections and blackheads. Its antioxidant property enables it to protect skin from external damage.
Iris Extract: Iris extract contains flavonoids that give it anti-microbial and anti-inflammatory properties. In addition, its tannins have an astringent effect. It helps tighten the skin’s pores and soothes and softens the skin.
