Brighten up your eyes with this long-lasting primer ($26), recommended by Guyton.
Control oil and shine with a dusting of translucent powder, recommends Guyton.
"Use a liquid foundation for spot coverage under the summer and a concealer under the eyes for daytime," says Guyton. This one from Make Up For Ever is a beauty editor favorite.
"Moisturizer can be a little heavy during summer months. Try a hydrating serum instead, like this one from Oil of Olay," says Guyton.
"This SPF goes on like silk," says Guyton.
