Boscia Vitamin B12 Hydration Booster Serum This new Boscia Vitamin B12 Hydration Booster Serum ($46) is like a B12 shot, but for your skin. That vitamin helps support the growth of healthy cells and mends tired, dry skin — and all you need to do is shake to mix up the (squalane and apricot) oil and water before rubbing on your face.
