An Honest Biologique Recherche P50 Lotion Review

A cult following in a bottle.

You've seen it in the shelfies of your favourite MUAs, bloggers and models. But what's it all about?

Lockdown is all but coming to a close (don't let us jinx it) and you've decided that your skin needs some serious TLC. We've spent what feels like three years indoors, consuming copious amounts of wine, butter and crisps (while saving civilisation, nbd) and now our skin is paying for it. 

Dull, congested and somehow grey (?) you need something that packs a punch rather than the 400 half-empty bottles of pointless products you have at home. 

After extensively testing out a myriad of highly-rated products, I have the one for you.

To provide some context, I suffered from pretty bad skin throughout my teenage years until I was prescribed medication. As a result, I gave up hope in any products that promised they would 'zap spots overnight'. (PSA: Never buy Clearasil, it is to skin what paint stripper is to Monet).

In my twenties, I've found love (through trial and error) with a number of fail-safe products that I would only even try if recommended to me by a professional. One of these is Biologique Recherche Lotion P50. 

An aggressive exfoliator in my youth (microbeads! sea salt! loofahs!) I've realised that my skin takes far better to chemical exfoliants. They shed away the dull and grey without compromising tiny microtears across your cheeks that will likely take years to fade. My Celtic skin loves a weekly chemical exfoliant because it doesn't make me look like I've come out in a rash, quite frankly, while also giving me the gleaming results that I want. 

I've messed around with a few for years but the P50 Lotion has changed the game for my face. To put things into perspective – in the past few weeks since I've started using it, I've been told thrice that my skin looks great (heroin to someone whose life was paved by way of hormonal acne).

Lotion P50 is one of the purest and strongest exfoliating lotions (except for ‘1970’) from Biologique Recherche (and on the market).

Exfoliating toners enhance epidermis’ natural exfoliating process and skin’s self-regeneration potential. When we exfoliate the “new” young skin cells promote a brighter, spit free, evenly toned and healthy-looking complexion.

With P50 there are also purifying, antiseptic and sebum-regulating ingredients, which can be excellent if you’re prone to blemishes and oiliness.

Hello - happy Friday Jr! 殺 I have a new blog post up on my favorites this month and any products I emptied in May. Read it using the link in my bio. 朗⁣ ⁣ Spoiler: I started using @biologique_recherche p50 1970 again and I am in love. It’s the only active I’ve been using in my routine and my skin looks so much better - pores are tiiiiiny, skin is glowing, and spots are fading. I love her.⁣ ⁣ Also, check out my stories to see what I emptied this month!

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

While I could talk about the benefits of acids forever (more on that here) The Lotion P50 exfoliating cocktail is a potent combination of AHA, BHA and PHA: lactic acid, malic acid, citric acid, salicylic acid and gluconolactone.

These acids exfoliate, moisturise and encourage the regrowth of new skin cells efficiently. In other words, they scrap away the old, protect the new and kickstart the anti-ageing effect in one fell swoop. 

The product also purifies and regulates sebum (a skin substance that seals in moisture and prevents skin from becoming over dry) production by way of the essential oils inside. 

Niacinamide (B3) also features which helps by providing a specific type of moisture that is known to 'smooth' wrinkles. There’s a couple of preservatives on the bottom of the list, but nothing extra such as fragrances or dyes.


Apart from its celebrity fan-club, P50 is also known for its scent. That is, it smells of vinegar. So be prepared for that. As someone whose skin is forever sensitive, I was a little worried it would sting. It didn't for me, unless my face was soaking wet post-cleanser. So keep that in mind. The scent isn't overpowering but be prepared that it definitely hints more at a chemical mixture than it does roses and patchouli. 

I put about two splashes of the Lotion P50 to a reusable cotton pad (I am obsessed with these, you can get them here) and gently pat all over the face. According to Biologique Recherche's head honchos, you should press and release. Do not wipe or rub. You can press extra to areas of concern, like the crevices of the nose.

As a result of this, I have found my skin feeling fresher, cleaner and so, so much brighter. It also seems to be helping with my chin that has been covered in acne scars since my teens. I always felt like that area looked like it had been chewed up and spat out – but I really do feel like P50 is doing its job. I go without makeup most days now and don't even think about it! What a time to be alive. 


I can't believe I went so long without trying this product. As soon as I'm finished writing this, I'm buying one for my mother – which is when you know I think it's good. 

For those keen to buy in Ireland, you can do so at Skin By Olga Salon, The Merrion Hotel's SpaFLORAISON and Melissa Ferguson in Adare, Limerick. 

Happy exfoliating.
