Dual+
Azelaic Acid is a multi-disciplinary ingredient to treat acne breakouts and hyperpigmentation spots with different benefits on the skin: It kills acne bacteria, prevents keratinization, inhibits the tyrosinase enzyme and is comedolytic. Thanks to its high 10% concentration, it helps eliminate acne breakouts, decongests pores, softens irregular texture and blurs hyper-pigmentation spots.
According to approved scientific studies, 20% Azelaic Acid is equivalent to 4% Hydroquinone (this ingredient is used by dermatologists under medical prescription to treat hyper-pigmentation spots. Hydroquinone is prohibited as a cosmetic product in Europe).
Potassium Azeloyl Diglycinate is a derivative of azelaic acid with glycine grafts, which reduces sebum production and inhibits tyrosinase. Additionally, Glycine, thanks to its hydroscopic properties, moisturizes the skin. Its 3% percentage illuminates the skin and moisturizes.
Alpha-Arbutin is a derivative of hydroquinone and is one of the most powerful ingredients that fights against tyrosinase, reducing the production of melanin. Its 2% percentage illuminates the skin, unifies uneven tone and blurs dark spots.
Hexylresorcinol is an innovative brightening agent that reduces melanin synthesis, acting at different levels of the melanogenesis process. Its 1% percentage in the formula blurs hyper-pigmentation spots, and also has illuminating and anti-microbial properties, making it the perfect complement for acne spots.
