THE latest anti-ageing product from SK-II is Signs Treatment Totality (STT), which claims to help work on skin’s firmness and signs of ageing.
STT is an enhanced version of SK-II’s best-selling Advanced Signs Treatment. Designed to help achieve youthful and naturally radiant skin, its key ingredient is niacinamide, a form of vitamin B3. The ingredient is said to be a primary source for skin cell renewal, helping to activate overall turnover of the epidermis (outermost layer of skin) and function of epidermal cells.
