I always tell people beautiful make-up starts with properly prepped skin. Think of your face as a canvas. If your skin is well hydrated and smooth, your make-up will look it’s best. I have extremely dry skin and I have been using primers for the past ten years. I often switch between primers depending on how my skin is behaving at different times of the year. This Hourglass No 28 Primer Serum, $22 for .33 oz. at Sephora, is extremely hydrating. It is more of a treatment than a primer in my opinion, but it does help fill in those fine lines. It is not your typical dimethicone based primer. If you are looking for a primer that is more of a filler, this is not it. This primer calms, soothes, and hydrates your skin perfectly. It contains a blend of 14 essential oils, 10 lipid-rich plant oils, and four vitamins. You should let this primer sink in for a few minutes before you apply your foundation. I find on the days when my skin is extremely dehydrated or fatigued, this is definitely the primer I reach for. It gives your skin a dewy appearance which only gets better as the day goes on. If you have oily skin, you would probably want to skip this during the day. This primer can also be used as a treatment by itself. I sometimes apply this on my freshly cleansed skin before bed. Hourglass primer is a must have for those cold winter days. Prime away!
