When it comes to skincare, few products have achieved the legendary status of Biologique Recherche’s Lotion P50.

Loved by beauty experts and skincare enthusiasts alike, this iconic exfoliating toner has become the cornerstone of the Biologique Recherche routine.

It’s all in the name

The ‘P’ in ‘P50’ stands for ‘peeling,’ as the product helps to encourage the skin’s exfoliation process for a revitalized appearance. The number ‘50’ refers to the approximate number of days it takes to see results. This time frame corresponds to the duration of two skin cycles, during which the active ingredients work to exfoliate and regenerate the skin.

Why a P50 dupe is hard to come by

Among the reasons P50 cannot be easily duplicated is its unique formulation, production process, and concentration of ingredients. Over the course of its 50-year history, the proprietary manufacturing process has been meticulously considered at every stage.

The Philosophy

Lotion P50 was created by Biologique Recherche Founder Yvan Allouche in 1970 as a way to gently exfoliate the skin, regulate excess sebum secretion, moisturize and help maintain the epidermis’ pH level.

As his son, Dr. Philippe Allouch explains:

“My father understood that skin had to be respected and he wanted to create something to rebuild the epidermis. He thought it would be better to have a gradual, soft exfoliation with acids that could also enrich the natural moisturizing factor in our skin. Although exfoliation is a natural process whereby the skin gets rid of dead cells, it slows down with age. We do not believe in facial scrubs repeatedly using strong peels, extractions or anything else that is going to weaken or potentially damage the epidermis. It is tremendously important to have a fully potent and strong epidermis, as it impacts the overall health and look of skin.

Instead, we use products that restore and strengthen the protective barrier function of the epidermis, accelerate epidermal reconstruction and restructure by boosting the repair capacity of damaged skin. The process is not immediate—nor should it be—but it is well used for a progressively balanced skin. Lotion P50 has always been a product of its time, and it will continue to be. If someone loves this product, they will love it for the rest of their life.”
