Frequently asked questions
What is bemotrizinol (Parsol Shield)?
Bemotrizinol (trade name Parsol Shield; also known as Tinosorb S) is a broad-spectrum UVA+UVB filter that is highly photostable. On June 9, 2026 the FDA approved it — the first new sunscreen active added to the US monograph since the 1990s — for adults and children 6 months and older at up to 6%.
Are next-gen UV filters better than older ones?
Newer filters such as bemotrizinol, bisoctrizole and Mexoryl 400 generally give broader, more even UVA coverage and far better photostability than older ones like avobenzone, which degrades in sunlight. They also tend to feel more elegant — though applying enough and reapplying still matter most.
