Renew your complexion with the REN Resurfacing AHA Concentrate, a powerful nightly treatment that reveals fresher skin upon waking. Created for those with dull & tired skin, this complex of fruit acids gently exfoliates to enhance the radiance & tone of your complexion. The treatment is suitable for all skin types, but is not recommended for those who have particularly sensitive or reactive skin. After use pore size & fine lines are reduced & moisture retention is enhanced, boosting the efficacy of your skincare routine. This blend of naturally exfoliating acids is made up of glycolic acid from pineapple, lactic acid from passion fruit, citrus acid from lemon & tartaric acid from grape to ensure brighter, smoother & more radiant skin. Apply one pipette to clean skin, avoiding the eye area. Follow with your usual night serum & moisturiser. Slight tingling may be experienced during application, not suitable for sensitive skin.
