Based on its formula, is this product safe for sensitive, acne-prone, or dry skin?

It is generally well suited for normal to dry skin thanks to moisturizers like glycerin, but the presence of alcohol denat., fragrance and several synthetic UV filters can cause irritation on very sensitive or acne-prone skin, so a patch test is recommended.

What is the role and benefit of diethylaminohydroxybenzoyl hexyl benzoate in this sunscreen?

Diethylaminohydroxybenzoyl hexyl benzoate (also known as Uvinul A Plus) acts as a broad-spectrum UVA filter that is highly photostable, helping to prevent sun-induced skin aging and sunburn while maintaining a clear, non-white cast.

Product Insights

Lait Solaire WaterLover SPF 50 is a 200 ml water-based sunscreen lotion from Biotherm that provides high UVA/UVB protection with a blend of modern chemical filters such as diethylaminohydroxybenzoyl hexyl benzoate, phenylbenzimidazole sulfonic acid, drometrizole trisiloxane and ethylhexyl triazone. The formula includes skin-friendly ingredients like glycerin, propanediol and antioxidant vitamin E, but it also contains alcohol denat., fragrance and several synthetic UV absorbers that can irritate very sensitive or acne-prone skin. Certified by the Nordic Swan ecolabel and delivered in a convenient pump, the product is classified in the ultra-processed NOVA 4 group and lists six additives, which may be a drawback for consumers seeking minimalist cosmetics.
