Discoloration is the result of excess or deficiency of melanin. They appear most often as a result of exposure to UV radiation. They can also occur in people with mature skin and when using certain medications. Treatments that lighten discolorations lighten them and inhibit the melanin production process. They are made using acids, vitamins and retinoids. Arkana's offer also includes acne treatment, which occurs as a result of inflammatory changes. A treatment that brightens discolorations provides the skin with valuable nutrients, thanks to which it can effectively protect itself against the influence of external factors.
