We compared two invisible-finish SPF50+ face sun creams: the La Roche-Posay Anthelios UVMune 400 Invisible Fluid and the Garnier Ambre Solaire Super UV Invisible Serum.
What we looked at
UV protection stated in the listings, texture, resistance and fragrance, extra ingredients, bottle size, and price. We compared single-bottle listings only.
The verdict
If you want a larger 50ml, fragrance-free fluid with the Mexoryl 400 filter and stated water, sweat and sand resistance, the La Roche-Posay is the active, sensitive-skin pick, at £13.98. If you want a lighter everyday serum with ceramide and hyaluronic acid in a vegan formula for under £9 a bottle, the Garnier is the value option, though it is a smaller 30ml and does not list water resistance.

A larger 50ml fragrance-free fluid with Mexoryl 400 and stated water, sweat and sand resistance, but it costs £5 more per bottle.

A lighter vegan serum with ceramide and hyaluronic acid for under £9, but a smaller 30ml bottle with no water resistance listed.
