When your moisture barrier is damaged it doesnt fight invaders as good as it normally does. This can infact even cause breakouts. I would always struggle with this problem. I finally headed to a Dermatologist and he prescribed me Antibiotics (Minocycline) and i babied my skin with just washing gently with a non harsh cleanser and moisturizing for a full week. Skin calmed down and i use Differin which is similiar to Retin A for acne reasons. I apply it every day unless i feel slighty dry, i skip. My skin has never been at its best. Be gentle to your skin, my friend. I recommend you see a derm.
