How to Layer Anti-Aging Actives
Use vitamin C and peptides in the morning, a retinoid at night, and never combine strong retinoids with acids the same evening. SPF every day is what makes any of this work — UV is the primary driver of visible aging.
FAQ
Retinoid or peptide first? Retinoids have the strongest evidence; peptides are a gentle complement, not a replacement.
When will I see results? Texture in 4-8 weeks; lines and firmness over 3-6 months of consistent use.
Conclusion
The Ordinary Retinol is the best evidence-based value; MEDITHERAPY retinal a strong step up. Pair any of these with daily SPF and consistency. That combination, not a single miracle serum, delivers real anti-aging results.
