Beauty lovers, it’s the end of an era! The iconic Biologique Recherche P50 1970—the holy grail exfoliating toner that has graced skincare routines for decades—is being discontinued. If you've been a loyal fan of this cult classic or are just discovering it, this is your last chance to stock up before it disappears forever.
As someone who has used and loved P50 1970 in my morning routine, I’ll definitely be stocking up. Today, I’m here to share the story behind this skincare legend and explore some amazing alternatives to carry us into the post-P50 1970 world. If you’re searching for a replacement, don't worry—I’ve done the research and will share my favorite options that cater to different skin needs. Below, you will also find head-to-head comparisons to help you decide what's right for YOUR skin.
The Story of Biologique Recherche and P50 1970
Some skincare products stand the test of time, becoming true legends, and P50 1970 is one of them. For over 50 years, it has been celebrated for its ability to exfoliate, balance, and refine the skin. Created by the Allouche family in the late 1970s, Biologique Recherche developed this powerhouse formula with a unique combination of acids, active ingredients, and minimal fillers.
What Made P50 1970 Iconic?
Phenol: This controversial ingredient is part of what gave P50 1970 its signature antiseptic scent and transformative results. Known for its antibacterial and anti-inflammatory properties, phenol helped acne-prone skin achieve clarity.
Exfoliating Power: With lactic acid (AHA), salicylic acid (BHA), and niacinamide, this toner balanced oil production, brightened skin tone, and enhanced texture.
“Facial in a Bottle”: P50 1970 became synonymous with effective exfoliation, creating smoother and brighter skin while helping other skincare products absorb more effectively.
Why Is It Being Discontinued?
The inclusion of phenol, while effective, has been controversial for years. It’s banned in several countries due to safety regulations, and the beauty industry is increasingly shifting toward more universally accepted formulations. Biologique Recherche is adapting to this demand, retiring P50 1970 to focus on phenol-free alternatives. While this is a bittersweet goodbye, it opens the door for us to try other effective products!
What To Do Now?
If you’re as attached to P50 1970 as I am, this is your last chance to stock up. Trusted retailers still have it in stock, and the expiration date spans a couple of years. I’ve linked where you can purchase it below so you can grab a bottle before it’s gone. The non-phenol formulas are also fantastic and will still be available!
But if you’re ready to move on—or if P50 1970 isn’t of interest—there are excellent alternatives that deliver similar benefits at a fraction of the cost. Let’s explore a few standout options.
But first, here is the P50 1970 still in stock with expiration dates quite a ways out:
