I dabbed it on. My face turned neon pink. My eyes watered. Then I looked in the mirror — pores looked like they’d tucked themselves in.
That’s the thing about Biologique Recherche Lotion P50 1970. It doesn’t *ask* permission. It just chemically exfoliates your pores into submission. Fifty years later, people still wait months for a restock. Not because it’s pretty — it smells like vinegar and regret — but because it actually works.

🧪 **What You’re Getting Into**
$67 for 5.1 oz. That’s not cheap for something that smells like a pickle jar. But the claim? “Pore refiner.” I rolled my eyes, bought it anyway.
Phenol delivery system
Carries ingredients deeper than water-based toners can reach — that’s why it stings
No pH buffer
Sits at a pH low enough to actually exfoliate, not just “gently” pretend
Sulfur base
Not just acid — sulfur calms the inflammation acids can cause

💥 **The Acid Lineup**
This isn’t a one-note toner. It’s a cocktail designed to dissolve everything stuck in your pores.
- Lactic Acid: loosens dead skin without stripping
- Salicylic Acid: dives into oil glands, clears blackheads
- Acetic Acid (vinegar): antibacterial, tightens texture
- Sulfur: dries active breakouts overnight

📋 **The First Dab**
It’s watery. Almost thin. Dries in 8 seconds flat. Your face will tingle — some call it burn, I call it working. Week two: my nose texture went from strawberry to smooth. What surprised me? No purging. Usually acids push everything out first. This just… refined.

💸 **Did It Actually Do Anything?**
Yes. Pores visibly smaller. Texture smoother. Breakouts? Fewer, but not zero — it’s not magic. What stayed the same: my dry patches. This won’t hydrate you.

✅ **Bottom Line**
It’s the real thing — not hype. Just be ready for the sting.
