For people with sensitive skin, the less product they use, the better. This also applies to the amounts of ingredients, less ingredients -the better. For people with oily skin, stick with water-based product or gel or liquid. My skin is sensitive AND oily. I avoid using too much product because it can give my skin a ‘heavy’ unpleasant feeling. It can also make my oily skin more oily throughout the day. That’s why I use less product in the morning. There’s only 3 steps of my morning time routine: cleansing, base, powdering.
