This cult coveted, all-in-one exfoliating, balancing and toning lotion purifies, brightens and regenerates the skin. It balances your skin’s pH, regulates sebum and hydrates the top layers of the epidermis while improving the efficacy of serums and products applied after.

Lotion P50T is a vitamin-enriched exfoliating lotion containing AHA’s, BHA’s and PHA’s to gently resurface the skin alongside niacinamide and horseradish to brighten and arnica to calm. 

This sophisticated and unique lotion speeds up the epidermis’ natural exfoliating process and the reconstruction of the epidermal shield. The fortified epidermis can then fulfil its protective functions completely, enhancing the skin’s self-regeneration potential. As its name indicates, the Lotions P50 gently renews the skin over 50 days – ‘P’ stands for peeling and ‘50’ stands for 50 days – which represents about two epidermal cycles, for a gentle yet effective exfoliating process.

Recommended for sebhorreic, dull, congested skin.


The 1st week: Apply the lotion with a dampened cotton pad or ideally gauze over the face, neck and décolleté in an ascending motion from the center of the face out. Always dab or press the product in rather than dragging over the skin, this will give a much better result. 

As your skin’s pH starts to balance and becomes used to the acids in the lotion you can gradually start to apply the product to a dry cotton pad or gauze, so you are no longer neutralizing the acids. When the lotion is applied you may experience a slight tingling sensation, this is normal. 

**There can be a period of adjustment with P50 Lotions and sometimes the skin will purge, especially if there is underlying congestion in the skin which indicates an epidermal imbalance, and you may experience temporary dryness or sensitivity. This is normal and as your skin ph becomes more balanced which will improve the health of your skin and barrier function, you can expect to see great results. Stick with it through this phase, we promise the results are worth it!

To combat extra shininess or blemishes that may arise while your skin finds it’s balance, we recommend using Masque Vivant 2-3 x per week.

We offer medical gauze as an alternative to using cotton rounds as we find these absorb much less product and help to infuse the lotion evenly into your skin. Your bottle will last longer and you will see better results, more glow and less sensitivity!   


Do not use on scratched or irritated skin, nor during a treatment with retinoic acid or other peeling treatments. Avoid contact with eyes and the area around the eyes. If the product gets into the eyes, rinse thoroughly with clean water for 1 to 2 minutes. Avoid sun exposure immediately after applying the product. 

-There is no need to use a retinol along with this product, when used correctly you will get a wonderful result. When you are looking for a bit more resurfacing, or to give your skin an anti-aging, brightening or clarifying boost, I recommend rotating in Lotion MC110 used after your P50 until the bottle is finished, then for ultimate results you can rotate in Serum 3R after to renew, regenerate and repair the skin. Retinol can be damaging for some and this is a great option that I consistently see beautiful results with!
