Product details
Retinal is 11x more effective than retinol - and this serum makes it accessible for even sensitive skin. But what makes the CEL Retinal Serum genuinely different is the patent-pending CEL Complex: a bioactive blend developed by Skin Diligent's longevity scientists that targets 10 visible mechanisms of skin aging. With an ultra-light satin texture that absorbs instantly and leaves no residue, this is the night serum for skin that wants to age on its own terms. The CEL Retinal Serum combines 0.15% encapsulated slow-release retinal with the patent-pending CEL Complex, a bioactive blend of botanical extracts, peptides, and exosomes developed by Skin Diligent's longevity scientists. The encapsulation in natural botanical resin delivers retinal gradually for maximum efficacy and optimal tolerance - making this one of the rare retinal formulas suitable for sensitive and acne-prone skin. In an independent clinical study on 20 women aged 35 to 60, all with sensitive skin, 95% showed visibly smoother, firmer, and more even skin at 28 days - rising to 100% at 56 days. Formulated in France. Final formula tested to be free of estrogenic and androgenic endocrine disruption. Dermatologist tested.
