SkinMedica Retinol Complex 1.0 is the advanced-strength step in SkinMedica's physician-formulated retinol regimen, delivering 1.0% encapsulated retinol for patients who have successfully pre-conditioned their skin with Retinol Complex 0.5 or another retinoid product and are ready for maximum retinol efficacy. At this concentration, retinol produces the most clinically significant improvements in fine lines, wrinkles, skin texture, hyperpigmentation, and pore appearance — with encapsulation technology minimizing the irritation expected at this potency.Retinol (1.0%) at this concentration provides the most robust stimulation of collagen synthesis, cell turnover acceleration, and pigmentation correction available in a non-prescription retinoid formula. PhytoShield™ Complex encapsulates the retinol molecule — protecting it from oxidative degradation to maintain stability and potency, while buffering the skin against irritation during the adaptation phase through controlled, gradual release. Niacinamide reinforces the skin barrier during retinol use, reducing sensitivity and improving skin tone uniformity. Peptide Complex provides complementary collagen-stimulating support through growth factor receptor pathways. Ceramides maintain the lipid barrier integrity that high-concentration retinol can temporarily compromise, improving comfort and tolerance throughout use.Evening use only. Not for use during pregnancy, lactation, or if planning to become pregnant. Recommended for retinol-experienced skin only. Mild redness, peeling, and irritation are expected during adaptation. Use daily SPF 30+. Available at Beauty Riche — authorized SkinMedica retailer with same-day shipping.
