Patch testing may identify signs of allergies that are causing or contributing to sensitive skin. Otherwise, it's difficult for doctors to test for sensitive skin because so many factors can cause it. If your skin is prone to acne and redness – this ‘anti-blemish’ liquid makeup from Clinique contains medicated ingredients that help treat existing breakouts and keep them from coming back. Its non-irritating matte foundation formula helps blur out blemishes and also aids to neutralize redness. This dermatologist-tested, anti-blemish liquid makeup blends easily and provides sheer to moderate coverage. It keeps skin looking fresh all day long and is perfect for normal to dry and combination skin types. If you have oily skin, you might want to use a primer before you go in with this product. It’s available in eight shades.
