Lotion P50 1970 (The Original)


Lotion P50 1970 is an amazing vitamin-enriched exfoliating lotion that gently purifies, hydrates, tones, controls sebum and balances the skin, visibly improving many common skin conditions including white-heads, blackheads and symptoms of rosacea. Lotion P50 1970 prepares skin to receive Treatment Stage products by exfoliating and toning.

This balancing exfoliator is the unique fruit of 30 years of reflection and experience. It speeds up the epidermis' natural exfoliating process and the reconstruction of the epidermal shield. The fortified epidermis can then fulfill its protective functions completely, enhancing the skin's self-regeneration potential.  It is recommended for Normal, Oily, Acneic, or Blemish-Prone Skin



  • Exfoliating
  • Purifying

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).



Week 1: Apply the lotion with a damp cotton pad, dabbing over the face, neck and décolleté using upward strokes.

Beginning Week 2: Soak a cotton pad with just lotion

Your skin may feel a tingling sensation, this is the way Lotion P50 1970 works. It has active ingredients and penetrates deeper than most products on the market.

After cleansing with one of Biologique Recherche Cleansing Milks, or pH balanced cleanser of your choice, apply Biologique Recherche Lotion P50 1970 onto a cotton pad. Starting at the decollete move upward to the neck and face. Use a gentle patting motion. Allow Lotion P50 1970 to penetrate before applying the next product.

Use Lotion P50 1970 morning and night after cleansing your skin. Lotion P50 1970 is also recommended to be used before using Biologique Recherche Masques and LiftKiss for optimal absorption and effectiveness.
