Chapter III · The Deep Dive
Our expert's complete verdict.
The Biologique Recherche Lotion P50 is a cult-favorite chemical exfoliant designed to resurface, hydrate, and balance the skin's pH. It is a highly potent multi-acid toner that combines AHAs, BHAs, and PHAs with botanical extracts to improve skin texture and clarity.
🟡 Gesamtbewertung: Mäßig bedenklich
The product is a high-performance formula that is generally safe but carries a risk of irritation due to its high concentration of various acids and pungent botanical extracts. While it avoids many harmful synthetics, the presence of potential allergens and the sheer potency of the active ingredients require a cautious application.

Fazit und Empfehlung
Fazit: Lotion P50 is a sophisticated, professional-grade toner that delivers significant results for skin texture and acne management. However, its complex mixture of acids and "medicinal" botanical extracts makes it a very "active" product that can be overwhelming for some.
Empfehlung:
- ◈Für wen geeignet? Best for oily, acne-prone, or thick/dull skin types looking for intensive resurfacing.
- ◈Besondere Hinweise: Start slowly (2-3 times a week) and expect a tingling sensation or a slight smell of vinegar/sulfur; Hinweis: Always apply a broad-spectrum SPF during the day as acids increase sun sensitivity.
- ◈Kaufempfehlung: Yes, for users who are already experienced with chemical exfoliants and seek a high-end, effective solution.
