If you suffer from rosacea or have natural redness to your cheeks, it is important not to accentuate the tone. When searching for a new blush play on colors that mute the redness. First, you want to neutralize the tone of the skin by applying your base (foundation/concealer). Then you want to pick a tone that complements the redness. Focusing on bronzy or peachy undertones. This also helps with your sensitivities as well. Typical red blushes on the market have the color Red 40 which is a popular shade that increases sensitivities.
