"One of my favourite sunscreens for children and babies over 6 months old is SunSense Kids (£15). This is a broad-spectrum SPF 50 UVA/UVB lotion which is also fragrance-free, so it's great for sensitive or delicate skin. It's easy to spread, nonsticky, and water-resistant for up to four hours, however I would still recommend topping up immediately after swimming, sweating, or towelling off." — Justine Kluk, consultant dermatologist
