Ren - Glycolactic Radiance Renewal Mask. A potent bio active peel mask designed to refresh and renew the complexion, reduce fine lines and dramatically improve skin tone and radiance. Formulated with a 100% pure, natural fruit acid complex of lactic, tartaric, citric and glycolic acid plus papain enzyme, this highly active treatment mask provides a gentle yet potent exfoliating effect. The peel works hard to combat congestion, resurface uneven texture, reduce the appearance of fine lines and minimise post-blemish scarring, leaving skin looking healthy and seriously glowing.
