Lotion P50 Original "1970"

11 Review(s)


Like a Facial in a Bottle!  

" A cult favorite, P50 is a magic potion that does it all. Exfoliates, Hydrates, and Balances the pH of the skin, it's a prep step before any skincare." - Danuta Mieloch

Danuta recommends P50 for everyone, even those with super sensitive skin (should use P50V a milder version).  P50 "1970" is the most effective and most commonly used formula of P50.  If you are still unsure which formula is most suitable for you please contact us so that we may assist you.

What is the connection between PH and good skin? 
Epidermal PH is usually acid reflecting the good status of the natural moisturizing factor, and the acid mantle of the skin (anti-microbial shield and chemical protection screen). However, the epidermis PH may vary considerably during the day, suffering from different artifacts. Epidermal surface PH is difficult to monitor and not always the best parameter for assessing the health of epidermis.

What makes the skin tingle when using P50?
When the epidermis is unbalanced, patients feel the acidity of the solution, causing the skin-tingling sensation. Once you reach a balance, this sensation will disappear.

What is the meaning of the name P50? 
The P can be used for potion or peeling (the first name of the product was Lotion P1970, then P50, P50V, and P50W were developed).

How To Use

A good skincare regime starts with a thorough cleansing.

Next apply Biologique Recherche P50 Original "1970" onto a cotton pad. Starting at the decollete move upward to the neck and face. Use a gentle patting motion.  Allow P50 to penetrate before applying the next product. Avoid eye area.

Please note: Your skin may feel a tingling sensation, this is the way P50 works. It has active ingredients and penetrates deeper than most products on the market. Watch our How To Exfoliate video!

It works. Review by Sienna
I want to hate this because of the chemicals but when I stop using it I see the difference within a week and it's not pretty. So I've used it for years with no plans on stopping. It stinks. It sometimes burns. It works. I see less overall redness and my mid thirties hormonal breakouts are less than they are without my p50. (Posted on 11/13/14)

Simply Awesome !!! Review by Erin
I am a licensed Aesthetician and have every product at my disposal. This product is by far in my top 5. Smells not so great but works amazingly. My skin type is ever changing and this really helps "normalize" it. Worth every penny and a little goes a long way. (Posted on 8/5/14)
I think I look a few years younger already. Review by Kathleen P
I tried the P50 last night and when I awoke this morning, I think I look a few years younger already. Well, at least, I have a bit of a "glow" going on, which to me, equates looking younger. =p (Posted on 7/23/14)
once you use it, you'll be hooked! Review by Anna C.
It's crack in a bottle, once you use it, you'll be hooked! Unlike crack, this is one product my skin cannot live without. The results are amazing (Posted on 7/22/14)
My Teenager's Hope In A Bottle & My Anti- Aging Secret! :-) Review by Anita S.
When I was first introduced to this product over a year ago I didn't write a review because at 42 you keep your age defying secrets to yourself (LOL! Ladies, you know I'm telling it like it is!) However, when consulted to have my 13 year old son use it for the cystic blackheads starting to pit his face from being inside his skin too long... that even the medication from the Doctor wasn't correcting the problem... It was time for me to help others with the same tragedy! In just two days with this product I saw it start to dissolve the blackheads and the whitehead stared to disappear completely. It's my prayers answered for my teenager's skin condition. (Posted on 7/18/14)
this works! Review by Mary
It is wonderful to use a product that actually lives up to the promises. After only a few weeks my skin looked so much better - breakouts gone, large pores almost invisible and a softer, smoother appearance - and this in the summer heat and humidity! I've even been able to stop using some other products because this one is so effective. So glad I tried it - getting the larger size this time! (Posted on 7/2/14)
