What do French people actually use it for?
Sunburn, mostly, and minor burns. It lives in the bathroom cabinet next to the plasters, not on the shelf with the serums. Ask a French person about Biafine and you will get a story about a bad afternoon at the beach, not a skincare routine.
Why did it go viral in America?
Because it is French, cheap, hard to get, and greasy in a way that photographs as dewy. Those four facts together are a marketing campaign nobody ran. Scarcity did most of the work.
Is it dangerous?
That is not the claim, and it is worth being precise. The concern raised by French dermatologists is about daily facial use of a product formulated for damaged skin — the wrong tool rather than a hazardous one. If you want the French pharmacy shelf as French people actually use it, that is a different list.
Questions, answered
What is Biafine used for?
Biafine is a French emulsion classified as a medicine, used for superficial burns, severe sunburn and certain skin lesions after radiotherapy. It is not intended as a daily moisturiser.
Is Biafine a moisturiser?
No. It is a medicine formulated for damaged skin. Its oily formula makes it feel like a rich moisturiser, which is why it has been adopted as one outside France, but that is not what it was made for.
Why is Biafine popular in America?
Because it is inexpensive, French, difficult to obtain in the United States and visibly dewy on camera. Scarcity and appearance drove the trend rather than the product’s actual purpose.
