Cytobiol™ Iris A is a botanical-vitamin-mineral complex with synergistic action of ingredients. Often used for its anti-inflammatory and astringent action, the iris extract is obtained using a production process that makes it possible to extract the active part of the rhizomes, particularly the glucosides, whilst also guaranteeing perfect reproducibility.
It is combined with a Zinc salt, well-known for its antiseptic properties and commonly used in dermatology as it inhibits the 5-alpha reductase enzyme; and Vitamin A which, at a dose of 200 international units per ml, is a growth factor that favors cell multiplication. It is also a tissue regenerator and “protector” of the epidermis. Vitamin A is recommended for oily skin as it regulates seborrhoea by inhibiting the synthesis of lipids.
Two clinical studies, conducted on volunteers, presenting both functional signs (pruritus, superficial skin tightness, and a burning sensation) and physical signs (folliculitis, comedones, erythrosis) of untreated acneic lesions, showed a clear improvement in the pre-existing acneic lesions in 75% of the cases by the 14th day of the studies.
After 28 days, 100% of the volunteers observed this improvement. The anti-seborrheic properties appeared clearly with an average decrease in sebum production for all regions of 12% at D14 and 25% at D28. And, the results of the in vitro study demonstrated that Cytobiol™ Iris A was effective in inhibiting bacterial growth at concentrations as low as 5% for both Staphylococcus epidermis and Corynebacterium acnes.Active ingredients (or INCI)
