A: Many people, just like yourself, have to deal with unwanted redness on their face and neck due to capillaries close to the skin's surface and rosacea. Generally speaking, there is little you can do to eliminate the condition, however there are wonderful products you can use to minimize the appearance.
Overall, you want to look for a yellow or green tinted product to reduce the appearance of red in your skin.
Clinique makes a great product, Redness Solutions Instant Relief Mineral Powder to not only help reduce the redness but also to "cool" the skin. Clinique also makes other creams to help reduce redness. The great thing about this product is that you can layer it to your desired coverage.
Other products that work well (and don't add "pounds" to your makeup) are skincare products such as Dr. Dennis Gross Hydra-Pure Redness Soothing Serum and Murad Redness Therapy Recovery Treatment Gel to help soothe your skin and prevent your blood vessels from dilating too much (which is one cause of redness).
Other than that, you can use Dermablend products, which are fairly lightweight and meant to cover imperfections such as rosacea, tattoos and port wine stains. There is even a Smooth Indulgence Redness Concealer you could use as well.
Make Up For Ever also makes a great, lightweight Full Cover Concealer if you wanted to use that as your foundation.
I would suggest going into Sephora and trying out some of the creams and serums to see how much they reduce your skin's natural flush. Then you can determine how much makeup you would need or want to cover any remaining redness.
