This is the only foundation/concealer I've used in the last 5 years. It covers imperfections you may have- acne, scarring, age spots, dark circles, veins. I just use a couple drops onto my clean fingers, tapping it lightly all over my face and neck (mix it with an SPF in the Summer) and either tap it into my skin with my fingers, a makeup sponge, or swirling with a big fluffy brush. Use any setting powder you like and ta-da! Good to go all day! $35. 10N has sold. Please see all pics for details.
