The Ultimate Guide To The Lotion P50 Range

“I’ve heard that the Lotion P50 is amazing, tell me about it” – one of the most common discussions that we have with clients here at the Embassy of Beauty is regarding our cult exfoliating lotions – the Biologique Recherche Lotion P50 range.

Often, beauty enthusiasts will have heard it being lauded as a must-have in magazines - it’s known as the best worldwide and has even been dubbed ‘a facial in a bottle.’

It’s true, it is a pretty special product. Here are some of the wonderful benefits these products have to offer:

· The hydroxy acids work to slough off dead skin cells and eliminate impurities, making it a powerful exfoliating lotion

· Tightens pores, making their appearance less visible

· Regulates sebum production and sebum secretion

· Unifies the complexion

· Hydrates, purifies and strengthens the skin

· Helps to balance the skin by regulating the pH levels

"What's All The Hype About?"

This is a product that’s really earned its stripes in skincare circles. It was first developed back in 1970 by the founder of Biologique Recherche Yvan Allouche.
The innovative chemist created these progressive lotions to facilitate a gentle but powerful daily exfoliation.

Biologique Recherche products are centred around epidermal reconditioning, and the name of this product is derived from "P" for peeling and "50" because
it takes two epidermal cycles, lasting 25 days on average, to achieve the first level of epidermal reconditioning required to renew the skin.

Because of the acidic pH of the lotions, they are multi-functional as they combine the benefits of a purifying, exfoliating, moisturising
and balancing the skin, all at once!

Biologique Recherche



Lotion P50V contains added vitamins and anti-ageing heroes like natural sponge and walnut extract.
It’s the best choice for duller and more mature skin.

Lotion P50V is more hydrating and restorative,
so should be the formula you reach for if you have dry skin.

Biologique Recherche



The Biologique Recherche Lotion P50 is the strongest form of P50.
It contains active ingredients such as thyme essential oil and myrrh for their purifying, toning, and antiseptic properties,
and is specifically formulated for thick or keratinised skin that needs a little more power to infiltrate the layers of the skin.

It’s also particularly good as a spot treatment on active and infected acne as it contains the highest concentrations of acids,
so it will burn through and eradicate the infection quickly.



Lotion P50 PIGM 400 contains added brightening ingredients and a host of antioxidants that unify the complexion,
reduce the size of pigmentation marks and prevent them from reappearing.  
It contains wasabi extract and red algae– potent sources of vitamin C that protect and illuminate the skin.

If pigmentation is your primary skin concern, Lotion P50 PIGM 400 is for you.

Five Things To Consider

With great power comes great responsibility, so let’s run through our top five tips for getting the most out of your Lotion P50.

- Apply it correctly

Use your Lotion P50 after your cleanser and before using serums or creams.

During the first two weeks of use, soak a dampened cotton pad with a few drops of your chosen Lotion P50 and dab it onto the face, neck and décolleté in upwards movements
(without rubbing and avoiding the eye area).

You will feel a slight tingling sensation, but no stinging or burning.

After a couple of weeks, switch to a dry cotton pad once you’ve established that your skin isn’t sensitive to the lotion.

- Don't use it alongside Retinol (Vitamin A)

Both Vitamin A (Retinol) and the chemical exfoliants in the Lotion P50 range stimulate cell renewal.

If you were to use them at the same time, it would lead to a host of problems, including sensitising your skin far too much, causing an imbalance or even burning the skin.
We are often asked if over the counter (as opposed to prescription) retinol
is OK to use at the same time – it’s a no from us.

Simplify your routine and stop using Retinol for two weeks before you enjoy your chosen Lotion P50.

- Use the one that is right for you

As we’ve discussed, there are four personalised formulations to choose from – choose between the Lotion P50W, Lotion P50V, Lotion P50 PIGM 400 and Lotion P50 depending on your skin.

We are often asked for the Lotion P50 1970. This contains Phenol which is no longer in use in the UK and Europe, but the Lotion P50 is just as effective.

  • - ...And at the correct time of day

Acid exfoliants and the sun don’t mix, as you want your skin to be protected from UV rays.

We therefore recommend using the Lotions P50 in the evening over summer and wear SPF,
and leave it at home when you’re going somewhere hot – it will still be there when you get home from your holidays!
