Skincare Review – Biologique Recherche Lotion P50

I’d like to introduce to you, my new love affair: Lotion P50. You might be unfamiliar with the brand Biologique Recherche (BR). The brand is based in France and it’s a cult status skincare line that is only sold through spas that offer specific BR facials and other dermis related procedures. You can, however, purchase the products online via the spas that have online stores, like Rescue Spa, Paul Labreque, and a few others in the US.

I came across Lotion P50 a few years ago while researching ways I could improve my skin texture and acne. I didn’t purchase it because it sounded kinda scary, and overpriced. I almost ordered it maybe three different times, but never followed through. Until last November! I gave in and finally ordered Lotion P50. I chose this version of the formulation because it seemed most appropriate for oily and acne-prone skin types. I was already an advanced user of AHAs and BHAs, so my skin has acclimated to acid cocktails. I got the 5.1oz bottle for $67 and I’ve never looked back.

The ingredients everyone is talking about

Water (Aqua), Gluconolactone, Lactic Acid, Glycerin, Propylene Glycol, Niacinamide, Citric Acid, Ethoxydiglycol, Magnesium Chloride, Malic Acid, Vinegar (Acetum), Phytic Acid, Salicylic Acid, Cochlearia Armoracia (Horseradish) Root Extract, Arctium Lappa Root (Burdock Root) Extract, Rumex Acetosa Leaf Extract, Myrtus Communis Extract, Commiphora Myrrha Resin Extract, Allium Cepa (Onion) Bulb Extract, Thymus Vulgaris (Thyme) Flower/Leaf Oil, Sulfur, Sorbitol, Phenoxyethanol, Sodium Benzoate, Potassium Sorbate.


I use this for two nights in a row, and then skip the next night to use a different treatment like retinoids, other brightening treatments, etc. When I do use it, I always double cleanse first to get rid of any makeup and sunscreen, then I apply Lotion P50 with a 2×2 gauge cloth by patting and pressing the product starting at the jawline, and moving up to the forehead. The remainder I use on my neck and decolletage. I follow with a hydrating serum and moisturizer or just moisturizer. Sometimes if I’m feeling extra congested I will use the P50 in the morning during my AM routine. I usually apply Paula’s Choice 2% Salicylic Acid every morning, but I use the P50 for that extra boost if my skin is really struggling.

What does it do?

What DOESN’T it do! I am so in love with the results this product has given me. I’ve now used this product for 2 months and I can say with confidence it has changed my skin for the best. It balances out the skin in a way that is not drying, irritating or clogging. It seems to be just what the skin needs to appear more “normal”. By normal I mean, not a greaseball. If you have oily skin, this will help you so much, without disrupting your skin barrier. The main claims I have seen results on are brightening, evening out of tone, smoothing of texture, aid in acne spots, a decrease of inflammation, and an overall glowy less shallow complexion. I actually have a progress highlight on my Instagram that you can check on to view the effects of P50 on my skin. I didn’t want to post those photos online because they are often stolen by companies to use as progress photos for their products.

What you should know

There are different formulas for every skin type. Each of the below comes as the plain version, but also as the “1970” version which means it contains phenol. Phenol is a controversial ingredient, and not something I’m willing to apply on my skin. If you’re interested in learning more and using the 1970 version, please do your research and educate yourself on the effects of phenol.
