The end of an ERA. Goodbye Biologique Recherche P50 1970

Beauty lovers, it’s the end of an era! The iconic Biologique Recherche P50 1970—the holy grail exfoliating toner that’s 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—and 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 already searching for a replacement, don’t worry—I’ve done the research, and I’ll 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.

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.

The inclusion of phenol, while effective, has been a point of controversy 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 appears to be adapting to this demand, retiring P50 1970 to focus on phenol-free alternatives. While this may be a bittersweet goodbye, it opens the door for us to try other effective products!

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 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.
