Really get a good cleansing system, really search for a non stripping product and stick with it, for me it was the revolution hydrating cleanser, ive used that for 5 months now and my skin was getting cleansed but not stripped so it allowed for that barrier to heal, go low on exfoliating never high, start on low percentages. Another thing is my skin started getting a lot better after introducing k beauty ( the Beauty of joseon sunscreen, purito unscented centella serum, derma cube centella medeca cream) they all gave my skin insane amount of hydration and protection and healing. I first started by doing a simple routine cleanser at night, low percentage exfoliant, and a heavy exclusive moisturizer. For mornings micellar water, then sunscreen. I then started introducing a targeted treatments like a retinol to really get the cells moving over and encourage healing, then really loading it with hydrators what load the skin with hydration. To top it all off once my skin was healing I would put a cocktail of antioxidants on my skin in the morning, vitamin b, c, e, root extracts etc then sunscreen to boost the benefits of the sunscreen and get better benefits from the protection.
