A Complete Review Of The Biologique Recherche Lotion P50

Here is a complete review of the Lotion P50 Biologique Recherche. In this post, I’ll go through why it’s important to exfoliate your skin, what is the Lotion P50 by Biologique Recherche, how to use it and what I think about this product.

Why You Need To Exfoliate Your Skin

Exfoliation is a natural phenomenon that occurs at every cycle of epidermis renewal when the epidermis sheds its dead cells; due to sun damage or genetics. However, this process can slow down especially when you age. If that superficial part of the epidermis is not taken off quickly enough, your complexion may appear dull and uneven.

That is why exfoliation should be part of your daily facial skincare routine to aid the natural exfoliation process. Exfoliation is one of the most effective ways to promote youthful skin. By exfoliating your skin, you will remove dead skin cells from the surface layer of your skin and improve your skin’s texture. It will bring fresh, new cells to the surface of your skin.

There are different ways to exfoliate your skin by using manual exfoliators, cleansing brushes, and chemical exfoliators. Manual exfoliators contain many different types of granules that eliminate dead skin cells from the surface of the skin. But nor the manual exfoliators or the cleansing brushes will replace the benefits of a well-formulated, acid-based exfoliator. I like to use the Caudalie Glycolic Peel Mask once a week. It leaves my skin so soft and bright. However, I was looking for an exfoliating toner and I wanted to try the Lotion P50 Biologique Recherche.

What Is The Lotion P50 By Biologique Recherche

Lotion P50 is a liquid balancing exfoliator that exfoliates the skin while regulating sebum production and maintaining the skin’s pH balance. This balancing and exfoliating lotion speed up the epidermis’ natural exfoliating process and the reconstruction of the epidermal shield. The P50 lotion not only exfoliates but also purifies, regenerates and maintains the pH of the skin.

There are four different versions of Biologique Recherche’s Lotions P50 available: the Lotion P50, the Lotion P50V, the Lotion P50W, and the Lotion P50 PIGM400. Each one provides the same core benefits, but their formulations change slightly to suit each and every skin. All formulas use effective exfoliating and reconditioning ingredients such as AHA (alpha hydroxy acids: salicylic acid), BHA (beta hydroxy acids: malic acid, lactic acid, citric acid), PHA (polyhydroxy acids: gluconolactone), cider vinegar and sulfur.

The Lotion P50

The Lotion P50 is the purest and the strongest formula with a high concentration of acids. It penetrates the epidermis quickly and is only suitable for thicker skins. It is an enriched exfoliating and purifying facial lotion recommended for dull and mature skin types.

The Lotion P50W

The Lotion P50W is a gentle exfoliating lotion that contains arnica to soothe the most sensitive skin types. This lotion is specially designed for thin to normal, sensitive skin.

The Lotion P50 PIGM400

Finally, the Lotion P50 PIGM400 has been specially designed for dull and pigmented skin types. This lotion contains brightening active ingredients and antioxidants.

How To Use The Biologique Recherche Lotion P50

I went to Liberty at the Biologique Recherche corner to choose the most appropriate formula for my skin type. I’ve been advised using the Lotion P50W which is the most gentle exfoliating lotion of the range. Indeed, the Lotion P50W enriched with arnica and specially designed for thin and sensitive skin types. The first two weeks are the “phase d’initialisation” which means that you need to dilute the Lotion P50W. Diluting the Lotion during the first two weeks will allow your skin to adapt to the strong formula. You just need to dampen a cotton pad and gently pat it all over the face and the neck like an essence.

After the “phase d’initialisation“, you can start using the Lotion P50W pure with a cotton pad all over the face and neck. It’s always better to use the Lotion P50W at night, after cleansing your skin, before your serum and your night cream. Make sure to stop using all other exfoliators like glycolic peels and retinol creams as well.

My Opinion On The Biologique Recherche Lotion P50W

First 2 Weeks Of Use

After the first application, I expected to feel the acidity of the solution and to feel the flush on my skin. But other than inhaling a strong vinegary scent, nothing happened. By the way, some people don’t like the smell (vinegar) but in this formulation, vinegar is working as a preservative instead of using alcohol for this purpose. After two weeks, I’ve started noticing the effect of Lotion P50W. Indeed, the acids tackle skin problems from every angle: resurfacing the skin, zapping all blemishes, healing acne scars and removing all dead skin cells. So that what you use after it is more able to penetrate.

After One Month of Use

This adoration period lasted exactly 4 weeks until my skin gets completely dehydrated! I could see all the fine lines due to dehydration, the texture of my skin completely changed also. Pimples due to dehydration appeared on my foreheads and I get also some redness on my cheeks. However, I do think my skin looked and felt more balanced. Indeed, my T-zone was less oily, my acne scars completely disappeared and overall my skin felt brighter and clearer.

I assume my skin is probably too thin or sensitive even for the Lotion P50W. Or maybe the night cream that I was using was not moisturizing enough to counteract the lotion. Indeed, I was using a mix of Dr. Hauschka Revitalising Day Cream and Dr. Hauschka Clarifying Day Oil. So if you’re using the lotion for the first time, in combination with the Lotion P50 I’ll recommend using the Biologique Recherche Placenta Crème. Apply a small amount of the cream after each application of the lotion in order to properly soothe and re-hydrate the skin.

After a month of use, I decided to give my skin a break and stop using Lotion P50W. As well as all other glycolic exfoliators in order for my skin to recover from dehydration. My skin was “plumper”, less dehydrated and dehydration fine lines were less visible. Currently, I’m using the Lotion P50W like a proper glycolic exfoliator. This means I’m only using it maximum once a week in order to let my skin more time to recover. I do think Lotion P50W from Biologique Recherche is a very good exfoliator. However, I don’t think your skin needs an exfoliation every day. I’ll recommend to use it like any other exfoliator this means maximum twice a week.
