What is the best skincare routine for anti-aging?

A core anti-aging routine includes: a morning antioxidant serum with vitamin C and ferulic acid, broad-spectrum SPF 30+, and at night a retinol or retinoid with a peptide moisturizer. Consistent SPF use is the single most impactful anti-aging step. Add AHA exfoliation one to two nights per week to accelerate cell turnover. Hydration with hyaluronic acid and barrier support with ceramides round out a comprehensive approach.
