Retinol

The evidence-backed anti-ageing active.

What it does

A vitamin A derivative that speeds up cell turnover — the best studied ingredient for lines and texture.

Anyone working on ageing or texture, once the barrier is healthy. Not while pregnant.

Evening only, on dry skin, starting two nights a week. Sunscreen the next day is not optional.

Not a hard no — usually a question of alternating nights rather than layering. Ask Sparkle AI about your specific combination.
