La Roche-Posay Retinol B3 Pure Retinol Serum ingredients: is it worth it?
A legitimate retinol serum weakened by drying alcohol and fragrance—not a sensitive-skin miracle.

A legitimate retinol serum weakened by drying alcohol and fragrance—not a sensitive-skin miracle.
READ MORE
The efficacy score is 4.0/5: retinol appears in position 11 and the brand identifies the formula as 0.3% retinol, giving it a credible anti-aging active, while niacinamide, glycerin, and sodium hyaluronate provide supporting barrier and hydration benefits. The score stays below the top tier because the retinol concentration is moderate, the formula also uses the weaker retinyl palmitate, the pH is not disclosed, and denatured alcohol appears very high in the list. The product's real anti-aging driver is retinol; fragrance, adenosine, and retinyl palmitate should not be treated as equivalent evidence-strength treatment actives. Alcohol and fragrance lower tolerability rather than cleansing or treatment efficacy.
