Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum Review

Our potent retinol serum is formulated with Pure Retinol in a daily-strength micro-dose, along with Ceramides and Peptides for hydrating moisture barrier support, to promote gentle skin surface turnover for youthful-looking skin. The precise micro-dose formulation of our anti-aging serum delivers visible results and is sensitive-skin friendly with minimal visible redness, dryness, or peeling. Wrinkles are visibly reduced, skin is firmer, pores appear minimized, and skin tone and texture are more even. Our retinol serum is a fast-absorbing, lightweight cream that is paraben-free, fragrance-free, mineral oil-free, and phthalate-free. It is precisely formulated to deliver a daily-strength dose of Pure Retinol for visible results with minimal discomfort, helping promote skin tolerance of Pure Retinol with Peptide and Ceramide for all skin types, including first-time Retinol users and sensitive skin types. In a clinical evaluation and expert grading in a clinical test after 12 weeks of use, 100% showed reduced fine lines and wrinkles and 90% showed improved skin firmness. In a consumer perception test after 12 weeks of use, 94% agree texture is refined, 92% agree skin tone looks more even, 88% agree pores look minimized, and 90% agree skin feels comfortable, even among first-time retinol users. For body anti-aging, based on expert grading in a clinical study with 54 panelists after 12 weeks, 92% agree skin looks firmer, 87% agree lines look minimized, and it is suitable for use on the hands, neck, and chest. Within the formula, Pure Retinol helps steadily accelerate skin surface turnover to bring new, fresh skin to the surface to address visible signs of aging for visibly renewed and youthful-looking skin. Ceramides, which are lipids naturally occurring in both skin and hair, help strengthen the moisture barrier to enhance skin's tolerance of Pure Retinol, while Peptide works to enhance skin integrity, helping it receive optimal, visible youth-renewing results. According to Kiehl's Global Scientific Director Dr. Nancy Ilaya PhD, the goal was to formulate a retinol product that could be used every day from the start with minimal discomforting effects while offering powerful anti-aging benefits, where peptide supports repair benefits and ceramides release vital skin barrier lipids to build retinol tolerance and prevent dryness without over-accelerating cell turnover or disrupting the skin barrier. After cleansing, apply the serum over the entire face, including the under-eye and crow's feet area, carefully avoiding contact with the eye, eyelid area, and lips, and always use with SPF if applied during the day.
