Slip this DERMATORY Shot Barrier Daily Ampoule fabric mask into your routine as a soothing “shot” every day. After cleansing and applying lotion/toner, place the mask over your entire face and leave it on for 10 to 20 minutes to let the B5 strengthen your skin barrier. Remove it, gently pat the remaining ampoule until absorbed, then follow with your moisturizer. Ideal for a daily treatment or a few times a week when your skin is sensitive or dehydrated.
