For several years I was the largest Tones Skeptics you would ever meet. “Glorified water”, I would spit and roll my eyes when someone recommended adding a tones to my Skin care routine. I saw them as unnecessary steps designed to empty our wallets, and gave nothing as a good detergent and moisturizer could not achieve. Every tones I tried to leave my skin feeling stripped, irritated or completely unchanged – just another bottle that touched my bathroom bench.
Then came Biological Research P50 1970. From the first application-trot its infamous vinegar-like scent, which made me question all my life choices, I was visible that this was different. The narrative tingle, the immediate clarity of my skin, and how my other products suddenly seemed to work better told me that this was not your average tones-this was skin care sorcery.
Within weeks, my skin was completely transformed. The stubborn congestion that had been my constant companion? Missing. The uneven structure that made makeup application a daily struggle? Leveled away. P50 1970 not only changed my skin; It changed my entire perspective on what a tones could be.
P50 1970 not only changed my skin; It changed my entire perspective on what a tones could be.
The magic was in its mixture of ingredients – phenol (yes, the controversial ingredient that made it so special), salicylic acid, lactic acid and niacinamide that worked together to get your skin into chess. It was like having a professional facial treatment in a bottle, which delivered results that made its eye -catching price tag seem completely motivated.
For several years, this miracle worker has been my skin’s best friend, my deserted island product, the one that is constant in a constantly changing skincare routine. Therefore, I felt that someone had punched me in the stomach when the brand announced that it was interrupted.
While newer P50 formulations will continue to exist, there will never be anything similar to the original version from 1970.
When I gently ration my remaining bottle (while planning how many backup bottles I can reasonably motivate hamstring), I am grateful for how this product completely transformed my skincare philosophy. Thanks, P50 1970, for proving this previous tones skeptical lovely, fantastic wrong.
