Lotion P50 Original "1970"


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).
