The Neostrata Restore range was formulated to provide powerful anti-ageing without irritation. It is ideal for patients with sensitive, rosacea prone skin or those who recently had cosmetic procedures and want potent anti-ageing without irritation. Poly Hydroxy Acids (PHAs) are second-generation hydroxyl acids which give the exfoliating benefit of hydroxyl acids without the irritation. Products in this range can be used with retinoid therapy to alleviate dryness.
