Everyone's skin ages differently, so there is no set age to start using anti-ageing moisturisers. Gradual changes in skin function, including a decline in collagen production, typically begin from the mid-20s. In your late 20s to early 30s, moisturisers formulated with ingredients such as vitamins C and E, hyaluronic acid, and niacinamide can help maintain hydration and support overall skin quality. As signs of ageing become more visible, formulations containing ingredients such as retinol, peptides, and richer emollients can help improve the appearance of fine lines, wrinkles, and age spots, while supporting smoother-looking skin.
