Please note: I only use TO Glycolic Acid twice a week in place of Differin and TO Azelaic Acid. I apply my toner, then snail mucin to already damp skin, than seal it in with a small amount of CeraVe moisturizer. This helps prevent trans epidermal water loss. After my skin is dry, then I will continue on with the rest of my routine. At night, after I apply Differin and Azelaic Acid or Glycolic Acid, I will apply another thicker layer of moisturizer and then use Cetaphil Repairing Balm to slug it out. It's much better than plain petroleum jelly because it dries down almost matte and has added ingredients to help with hydration and redness.
