Biologique Recherche Lotion P50 1970 – 50 ml (1.7 oz) Brand new and never opened. This is the iconic “1970” formula—known for delivering smooth, balanced, glowing skin. Ideal for daily exfoliation. I want to be transparent that the printed expiration is 12/2025, which means it’s good through the end of this month. If you’ve been wanting to try P50 1970 or need a smaller size before committing to a full bottle, this is a great chance to get it at a discounted price. Biologique Recherche is a highly reputable, luxury skincare brand, and this formula is often hard to find.
