"I really like Ultrasun Family (£18). I use it on my two children, especially on beach holidays when it's really hot as they're prone to heat rash and I find that this sunscreen doesn't exacerbate it. Also, it's not greasy, it's easy to apply, and it's got waterproof capabilities, so even as they get in and out of the pool, I know they have some protection." — Dija Ayodele, aesthetician and founder of West Room Aesthetics and the Black Skin Directory
