{"type":"firestarter.listing","listing":{"id":"lst_SsmgLioQ","product_name":"Retinol Serum for Sensitive Skin | Resurfacing 1% Retinol Light","category":"Skin Care","description":"Most retinol serums are water-based. Water feels familiar, but it is not the most effective environment for retinol delivery, and for sensitive skin, it is often what causes the irritation.\nThis is not a water-based serum.\nThe Resurfacing 1% Retinol Light is an anhydrous, lipid-based retinol treatment formulated for sensitive skin that still needs real results. The lipid delivery system works with the skin's own architecture, allowing retinol to integrate more gradually and with significantly less reactivity than conventional water-based formulas.\nUsed once or twice weekly, it helps improve the appearance of fine lines, uneven tone, discoloration, and skin texture over time. Tetrahexyldecyl Ascorbate, a stable, lipid-soluble form of Vitamin C is included to support brightening and help buffer retinol activity.\nThe texture is rich and concentrated. A small amount is sufficient.\nThis is a weekly treatment, not a daily moisturizer. It is for skin that wants retinol results without the recovery.\nUse as directed.
