It is best to use a concealer that contains an acne-fighting medication such as salicylic acid. For skin that has discoloration, adding a color-correcting concealer further hides blemishes.
To cover blemishes, prepare skin with a moisturizer formulated for sensitive skin. Next, apply a spot treatment to the area. Let this absorb into the skin before applying a light foundation that is oil-free with freshly washed hands or a clean brush. For skin that has redness, apply a small amount of green-tinted concealer before applying the foundation. Follow this up with a small amount of concealer that matches your skin tone. Blend this in with your fingertips by using a patting motion. Set the makeup with matte powder.
