Frequently asked questions

All Institut Esthederm products are designed to suit sensitive skin needs. However, if you have very sensitive and reactive skin, please be careful with products formulated with acids or retinol. Most Institut Esthederm products can be used on sensitive skin. The only products that you should be careful with if you have sensitive skin are Intensive AHA peel, Intensive Retinol oil Serum, Intensive Retinol Cream and Intensive Vitamine C Dual Concentrate.

Disclaimer: All Naos products, as recommended by the Cosmetic Regulation, are designed to minimize the allergenic potential. A specific safety assessment of the sensitization potential of each substance composing the product is undergone considering the targets and the conditions of use. When necessary and in line with ethical and scientific considerations, we can conduct further tests to confirm the minimum allergic potential of our products. Additionally, following the marketing of each of our products, a thorough in-house cosmetovigilance surveillance allows us to confirm the good tolerance. However, we have decided to remove from all the products the claim “hypoallergenic” as it is a claim that does not guarantee a complete absence of the risk of a personalised allergic reaction, which unfortunately although it is rare, can still occur.
