La Roche-Posay is a dermatologist-favourite for a reason: its sunscreens (the Anthelios line) and its niacinamide serum sit on genuinely strong evidence, and the formulations are well tolerated on sensitive skin. When it stays in the SPF-and-barrier lane, it's hard to fault.
Where we'd apply caution is the premium pricing on some "repair" and "anti-ageing" claims that rest on softer data. The sun protection is the standout – that's where the science is.
