iStem Retinol Detox Serum
Overnight renewal for visibly smoother, brighter skin — dark spots and blemish marks look faded within weeks.
This concentrated retinol serum for hyperpigmentation and wrinkles accelerates the look of surface renewal night after night, fading the appearance of blemish marks, dark spots and fine lines. Its encapsulated retinol releases in a controlled way — gradual, non-irritating brightening rather than a harsh peel — while stem cell technology supports the appearance of skin renewal. Hyaluronic acid floods skin with plumping hydration and antioxidants defend against oxidative stress for a more radiant, even-looking complexion. The featherlight texture absorbs fast with zero greasy residue, refining texture so skin looks smoother, firmer and visibly more luminous with every week of use.
