I keep my sunscreen in my purse at all times no matter the time of year. You never know when you will be in the car for a long period of time or leave the gym sweaty with no protection left on the face. The sun is not your skins friend. I also keep a moisturizer around because in the winter especially my skin gets really dry and needs a little extra hydration.
Lip enhancement complex (sold at Pure) is a MUST! I can't leave the house without the gloss that stays on forever. I keep oil absorbing papers with me to use throughout the day to blot the oils instead of adding on more makeup. Hope this helps you decide what to put in your bag. --Tatum, Aesthetician at Pure Aesthetic Medispa
