Anti-Ageing & Firming

The ingredients with real evidence behind them are few: retinoids, vitamin C, sunscreen and certain peptides. Retinoids have the strongest data for lines and texture, peptides signal for firmness without the irritation, and antioxidants defend against the damage that causes the problem in the first place. Sunscreen prevents more visible ageing than everything else combined, which is why it belongs in this category and not only in sun care.
