Biologique Recherche Lotion P50: A Review

What is P50?

P50 is predominantly an Alpha Hydroxy Acid treatment. It is unique in a way that it doesn't have Glycolic acid. It has Lactic acid, Malic acid, Phytic acid, some Salicylic acid (BHA) and some ingredients that help in brightening. All these will gently exfoliate the top layers of the epidermis and increase cell regeneration. It acts as a superficial skin peel. It also great for hydration, sebum control and good to prevent in grown hairs. It is supposed to reduce hyperpigmentation. This treatment is used like an 'acid toner'. For the first few uses, it is supposed to be diluted over a moistened cotton pad. After the skin gets used to the treatment, it can use used straight up over a dry cotton pad.

Shree's review:
Well to begin with, this is the only skincare product that I had done extensive research - read lots of reviews from different websites and skincare blogs. I also individually tried to find out the function and uses of each ingredient in it because, let's face it, this product has soooo many different acids in it! It's like giving an acid wash for your face.

P50 has been described as Jesus in a bottle by many. There are few others who have reacted very badly. I adore Caroline Hirons and being a regular reader of her blog. I wanted to try this product because Caroline has glowing reviews about this product. Su ordered it for me. I am happy I made a wise decision!

I started to use P50 once a week applied it on a wet cotton and patted it on my face. (I still continue to the same have never put it on a dry cotton). Yes it does sting! I was scared whether I have burned my face! The stinging stopped after about 15 minutes. After applying P50 I allow it to dry then layer on my serum or moisturiser.

In the morning I was surprised to see how my face looked - face looked clean, smooth, refined! The pimple that I had squeezed a day before which was red looked much calmer. It is truly an amazing product! Never in my life I have got a pimple and it disappeared like this! Now I use it 3 nights in a week and I wake up with beautiful skin. My acne scars are getting lighter. I have not got a single breakout since using this!

Do give it P50 a try! I am sure oily /combination skin with a bit of dehydration like mine will surely notice huge improvement! But start introducing it slowly. Well it is a concentrated skincare product.

Su's review: 

I came across P50 through a discussion in Beauty Heaven forums (thanks for the rec, RJ!). I am very impressed by P50. It is one the most dramatic products I have used that has given me clear skin. I graduated to using it in the concentrated way after my skin got used to it. I experienced a lot of stinging initially but my skin has gotten used to it. Actually I find that it stings less when used over a dry cotton pad than over a moistened pad. It smells strongly of vinegar (one of the ingredients). It is a bit unpleasant but it disappears after a while and doesn't bother me that much. I use it straight up and actually don't follow up with any moisturiser or serum (just like you are supposed to use Alpha H Liquid Gold). I don't feel the need for using any additional moisturiser, even though my skin is dry. I wake up with really beautiful clear skin. My skin looks plump and fresh. My pore size looks reduced. Any odd redness I had the previous night, would have calmed in the morning. I use it week-nightly and I am amazed by how my skin looks every morning after!

I haven't broken out ever since I have started using this (not even hormonal). My pigmentation is fading. My face has brightened a lot. General look and feel of my skin is clear and smooth. I have a few in grown hair on the bottom of my chin. P50, being the exfoliant that it is, it is taking away the upper layers of my skin and I am able easily pull out the in grown hair without them causing any folliculitis.

Our Verdict:

We both love this! It is our staple in our routine one and we wouldn't know what to do without it. Definitely the one for repurchase!
