Q: How do I make my foundation last longer during the day?

A hydrating skin prep. The lightest mid-day mist of Evian or coconut water. Gucci's best tips for making foundation last have everything to do with moisture. Dry skin has a disrupted pH, which makes even sheer coverage wear off faster. Choosing a formula with targeted ingredients helps—beyond its calming and plumping properties, Gucci formulated Vital Skin with clinical levels of vegetable-derived squalene and coconut oil so it would wear better and look better longer. And when it comes to the rest of your makeup, consider skipping moisture-absorbing powder. Here, Gucci shares her tricks for getting the most wear time out of your foundation.
