Retinol (Vitamin A)

Retinol is a proven anti-ageing ingredient, but the EU has set concentration limits due to toxicity concerns — particularly for pregnant women and products used on large body areas.

What is it?

Retinol is a form of Vitamin A used in skincare for its ability to stimulate cell turnover, boost collagen production, and reduce fine lines and hyperpigmentation. Other retinoids include retinal (retinaldehyde), retinyl palmitate, and prescription-strength tretinoin. Retinol converts to retinoic acid in the skin.

Where is it found?

Anti-ageing serums, night creams, eye creams, body lotions, and some sunscreens. Higher concentrations are found in targeted treatment products; lower levels in daily moisturisers.

EU regulation

The EU introduced new limits in 2025: retinol is capped at 0.3% in face products and 0.05% in body products. Retinyl palmitate and retinyl acetate are limited to 0.05% (equivalent retinol) in body lotions. Products must carry warnings against use during pregnancy. These limits were based on SCCS safety assessments.

Should you worry?

Retinol is safe and effective within EU limits for most adults. However, excessive Vitamin A intake (oral and topical combined) can cause toxicity. Pregnant women should avoid retinol entirely due to teratogenic risks. Start with low concentrations, use at night, and always wear sunscreen — retinol increases photosensitivity.
