I have rosacea on my cheeks/large pores. and dry skin on my forehead. I need a concelear and a foundation that will cover up rosacea and make me just look natural but that will last all day.
You should use a moisturizer on the dry areas of your face before you begin applying any makeup.
You should try a good foundation primer such as NARS Skin Smoothing Face Prep which prepares your skin for a flawless makeup application. Designed for trouble spots (fine lines, large pores, rough spots, and other imperfections), this formula creates a smoother and more even canvas for your foundation application. It creates a matte finish that leaves your skin feeling comfortable, not dry and you can find it at: http://sephora.com/browse/product.jhtml?id=P261210
A great concealer is Make Up For Ever Full Cover Concealer which is an ultra long-lasting, matte finish, oil-free, waterproof, full coverage concealer. You can find it at: http://sephora.com/browse/product.jhtml?id=P151107
A great foundation that is designed for skins with mild to moderate rosacea, and for dry, dry-combination, or oily-combination skin types is Clinique Redness Solutions Makeup SPF 15 which you can find at: http://sephora.com/browse/product.jhtml?id=P271903
I hope this helps you.
