For peptide serums in India right now, the biggest differences come down to **peptide type**, **formula stability**, **hydration support**, and whether you want **gentle anti-aging** or more aggressive wrinkle repair. Signal peptides like Matrixyl help with collagen support, while copper peptides focus more on repair and elasticity. Dermatologists also tend to prefer formulas that combine peptides with hydrating ingredients like hyaluronic acid or panthenol rather than peptides alone. ## Be
