For oily-skin types, Gallagher recommends the Laura Mercier Fusion Ultra-Longwear Foundation (£38). "It's a more lightweight version of your traditional velvet, matte, not-going-to-move-foundation," she says. "I'd also recommend this if you have things like redness and acne scarring that you want to cover but don't want to look like you've got lots of makeup on." A downside is that there aren't many shades to choose from with this foundation.
