Colour match
Some foundations can oxidise (this is when the formula reacts to air and changes colour – often turning a lot darker than it should be!) but MAC Studio Fix Tech Cream-to-powder Foundation, £30, bucks the trend. It’s pricey but you get what you pay for with this lightweight product that comes in a great variety of shades. It stays true to colour on application so you can avoid a make-up mismatch.
