The Purify line is the result of specialist research by Alphea laboratories which, through meticulous study of the epidermal physiology, have created a professional beauty treatment that offers innovative, targeted solutions for different types of oily, blemish-prone skin. These skin imperfections are often caused by the excess excretion of sebum and sweat, which results in oily, shiny skin that is prone to breakouts. Alphea Purify products develop a purifying, sebum-balancing and astringent action to counteract the excess sebum associated with oily skin types.
