Skin, Hair and Nail Problems

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

So I had this severe chicken pox when I was in my 9th garde and from that 2 or 3 years later I discovered that I have shingles. Now in my area there are cases of chicken pox and I don't know but I think my shingles got activated. So is it shingles or am I having chicken pox again?
