FREZYDERM SUN SCREEN VELVET FACE SPF50+, £17.50
If your foundation could ask for an SPF it would be this. It looks and feels just like a velvety primer and it works like one, too. Blurring imperfections and filling fine lines, the formula is completely non-greasy and even absorbs excess oil. Expect your base to stay matte for at least six hours and your make-up to have that just-applied freshness all day.
