Retinol, vitamin C, niacinamide, AHAs and sunscreen with their effective concentrations and realistic timelines.
Retinol is a vitamin A derivative; over-the-counter products typically contain 0.1% to 1% retinol. Retinoids increase skin cell turnover and support collagen production, which reduces fine lines over months of use. Nothing in this class produces a visible change in days.
Vitamin C, used as L-ascorbic acid, is an antioxidant formulated in serums at 10% to 20% concentration. It is best placed in the morning, where it works alongside daily broad-spectrum sunscreen — the single most effective anti-ageing measure, because UV exposure drives most visible skin ageing.
Niacinamide (vitamin B3) at 2% to 5% is well tolerated and pairs safely with most other active ingredients. It is commonly used as a buffer so a retinol routine stays comfortable while the skin adjusts.

Chemical exfoliants (AHAs) support texture a few nights per week but are not the primary driver of collagen-related change. Their role is tolerance and surface smoothness rather than wrinkle depth.
Sunscreen numbers: SPF 30 blocks about 97% of UVB rays and SPF 50 about 98%. Sunscreen is tested at 2 mg per square centimetre of skin — roughly half a teaspoon for the face alone — which is the dose that produces the labelled protection.
Read the concentration ranges as workable bands rather than targets to maximise. Over-the-counter retinol sits at 0.1% to 1%; vitamin C serums at 10% to 20%; niacinamide at 2% to 5%. Moving outside these bands raises irritation faster than it raises benefit.
