The La Roche-Posay Anthelios Ultra-Light Invisible Fluid Sun Cream SPF50 (£17.50) is loved by many dermatologists, including London-based dermatologist Dr Cristina Psomadakis, who said, "It has excellent UV protection, has a very light texture, and suits many skin types," and consultant dermatologist Dr Mary Sommerlad, who said it "was game changing when it first launched because it has no white cast and leaves a very elegant finish."
