KEY INGREDIENTS
- Azelaic Acid (10%): It is a multi-disciplinary ingredient for treating acne breakouts and hyperpigmentation spots with various skin benefits: It kills acne bacteria, prevents keratinization, inhibits the tyrosinase enzyme, and is comedolytic. Thanks to its high 10% concentration, it helps eliminate acne breakouts, unclogs pores, smooths uneven texture, and fades hyperpigmentation spots.
- Potassium Azeloyl Diglycinate (3%): it is a derivative of azelaic acid with glycine grafts), which reduces sebum production and inhibits tyrosinase. Additionally, Glycine, thanks to its hygroscopic properties, hydrates the skin.
- Alfa-Arbutin (2%): is a derivative of hydroquinone. It is one of the most potent ingredients that fights against tyrosinase, reducing melanin production. Its 2% concentration brightens the skin, evens out uneven tone, and fades dark spots.
- Hexylresorcinol (1%): It is an innovative brightening agent that reduces melanin synthesis, acting at different levels of the melanogenesis process. Its concentration in the formula at 1% fades hyperpigmentation spots, and it also has brightening and antimicrobial properties, making it the perfect complement for acne spots.
