For starters, it's crucial to repair your skin's barrier. Remove any products containing salicylic acid and vitamin C from your skincare routine for a couple of months. Could you please provide more details on the brand of your acid product? For the first step of cleansing, I recommend using micellar water from either Bioderma or an alternative from Eveline Cosmetics. For the second step, I suggest using Face Wash by CETAPHIL for Sensitive Combination to Oily Skin. As a base moisturizer, you may use the Ultra-Light Gel Moisturizer from CeraVe. If your skin still feels tight and peels, try using a cream that is thicker and more nourishing. This should help alleviate these issues and provide additional comfort and hydration to your skin.
I will get back to you later with ideas on how to clear your skin from acne. But first, the primary focus should be on restoring your skin's barrier function as it will help improve your skin's overall condition. Be prepared for a potentially long and gradual process as it can take time to properly treat acne. If over-the-counter or aesthetic products don’t work, a doctor may prescribe a systemic retinoid like the one I am currently using as a more potent treatment option.
