La Roche-Posay Anthelios Ultra-Light Invisible Fluid SPF 50+
"Generally, if budget isn't an issue, I tend to recommend the La Roche Posay Anthelios Ultra-Light Invisible Fluid SPF 50+ (£13, originally £17.50) since it seems to be well tolerated by even children with sensitive or eczema-prone skin." — Sreedhar Krishna, NHS consultant dermatologist and founder of the SkinDoc app
