For several days before your session avoid salty foods and alcohol which can dehydrate skin and cause puffy eyes, which will not make the camera fall in love with you. Exfoliate skin several times the week prior and wear a moisturizing mask to bed. Now is not the time to experiment with new products. Get plenty of water and fruits and vegetables in your diet. Have eyebrows shaped and groomed 1 to 2 days before if tweezing or 1 week before if waxing. Wax removes even the tiniest hairs causing the makeup to lay down differently. Exfoliate lips by applying Vaseline for several minutes then remove with rough wash cloth or soft toothbrush.
Think of a professional makeup artist as insurance for those special days when you want to look your best!
