What is Retinol?

Allergy & Safety Information

This ingredient carries moderate allergenicity risk. It can cause reactions in sensitised individuals but has a lower sensitisation rate than high-risk ingredients. Patch testing before full use is advisable for anyone with a history of cosmetic reactions.
About Active Ingredient Ingredients
Active ingredients are formulated to produce a specific skin benefit — exfoliation, brightening, anti-ageing, or acne treatment. They work by interacting directly with skin biology, which also means they carry higher irritation potential than passive ingredients like emollients or thickeners.
Relevance for Retinol: Actives often require an adjustment period during which temporary redness, dryness, or sensitivity is normal. However, persistent reactions after 4–6 weeks of use, or reactions that worsen rather than improve, suggest true intolerance. Introduce only one active at a time to identify the cause of any reaction.
How to Identify Retinol in Products

To check whether a product contains Retinol, scan the ingredient list for its INCI name exactly as it appears above. Ingredients present at 1% or less may appear in any order after the 1% threshold.
