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.
