The key to hiding an unwanted blemish is to "blend the concealer on and around it because you don't want the concealer, or the blemish underneath, to be obvious," says makeup artist Laura Geller
Before your makeup artist works her magic, cleanse your skin with a mildly exfoliating but gentle cleanser and follow up with a tinted anti-blemish cream, such as Guerlain's Crème Camphréa, suggests Lindsay Neeley, Assistant Director of Spa Operations at Guerlain Spa at the Waldorf Astoria Orlando. Adding, "The salicylic acid in the cream will go to work eliminating your blemish while the mild tint helps conceal and blends smoothly under makeup."
As for makeup, Geller recommends first using a primer to even out your skin's texture as much as possible. Next, apply concealer on and around the blemish, making sure to blend in the concealer and finish by setting with a translucent powder.
