The powerful activity of Enlighten is due to a skin remodeling ingredient (Retinaldehyde-liposome), multiple antioxidants and many lighteners (including Paper Mulberry) working synergistically to normalize skin tones. The nano-sized liposomes coating every active ingredient enhance penetration while protecting these delicate lighteners from oxidation. Our nano-liposome technology protects all 12 of the actives including Paper Mulberry (which was shown to be 10 times more potent than Hydroquinone) and dramatically improves penetration to their target, the melanocyte. It is also safe for use with pregnancy.
