Glycolic Acid: found in sugar cane, glycolic acid acts by dissolving the intercellular cement responsible for abnormal cell build up. Improves skin hydration by enhance moisture uptake as well as increased binding of water to the stratum corneum. Effective in helping clear the pores of acne prone skin, smoothing fine lines in older photo-aged skin and diminishing age spots.

Glycosaminoglycans: one of the newest available cosmetic ingredients, a complex of proteins that increases depth of hydration in cosmetics and with this, the elasticity and pliability of the skin. Moisturising and firming.
