La Roche-Posay Glycolic B5 Serum Dark Spot Corrector
La Roche-Posay
Overview
The La Roche-Posay Glycolic B5 Serum combines three well-researched ingredients for addressing hyperpigmentation and improving skin tone. While the specific concentrations are not disclosed, the combination of a potent AHA (Glycolic Acid) with tyrosinase inhibitors (Kojic Acid and TXA) and a skin barrier supporter (Vitamin B5) suggests a synergistic approach to dark spot correction and skin rejuvenation. The '0' amount per serving for each ingredient, however, indicates a lack of transparency regarding the exact dosage, which makes a precise efficacy assessment challenging.
The Good
Multi-ingredient approach targeting various aspects of dark spot formation.
Glycolic Acid promotes effective exfoliation and skin renewal.
Kojic Acid and TXA inhibit melanin production to reduce hyperpigmentation.
The Bad
Lack of disclosed ingredient concentrations (listed as '0'), making dose-response assessment impossible.
Glycolic Acid may cause initial irritation, redness, or sun sensitivity.
Kojic Acid can cause contact dermatitis, particularly in sensitive individuals.
Is it for you?
