I had a bad acne flare up due to an allergic reaction to protein supplements in august. I have applied my medications that were prescribed and I alternate between niacinamide and
vitamin c in my routine, apply sunscreen regularly and use non comedogenic moisturiser. The post flare up red marks are still not going away. The acne is gone just the marks are still there. Please provide a solution or a medication that can help on my combination but mostly dry skin
