If you use a topical glycolic acid / AHA, you should find that the scars fade a bit more quickly. It sluffs off and exfoliates the dead skin cells quicker. It helps build collagen and healthy tissues. It isn't a miracle by any means, but it does help. I'd used a 10% AHA for many years twice daily on my face. However, when you FIRST BEGIN you will feel stinging and may get redness and a purging of possible acne. Start with a very tiny amount every other day. See how that goes for a while and increase very slowly. No need to irritate the skin and cause a breakout by trying to go fast. I use a moisturizer over top or underneath the AHA every day.
EDIT: When I wrote this I was assuming your "scars" are mostly red marks or discoloration. If you're talking about indented scars. those are softened and made to look less obnoxious by the AHA, but it doesn't totally get rid of the true type of scar like that. My indented type scars look less noticeable after the AHA, but some are never going to totally go away under this approach. I'm okay with them though - they're not THAT horrible.
I'm no expert, but it sure looks like it is a mole. If it didn't have a tan coloring at the top, I'd think it might even be sebaceous hyperplasia but the coloring rules that out I believe, plus seb. hyperplasia has a tiny indent in the middle, and there's almost always lots of them rather than just one.
Dermatologists always have solutions to dealing with moles. I'm sure one of them would offer you some way to remove it if it is very upsetting to you. If they do suggest a way to remove it, however, take the information they give you and go home to research what it involves before having it done.
Sometimes having a harmless little thing removed turns out to be not that much fun or it can sometimes leave a mark behind. To be really honest, that mole is very small and not bad looking at all. The rest of your skin looks quite beautiful. Would it be terrible to keep it? I can't imagine anyone actually honinig in on it when they see you - it's not ugly. I mean that honestly.
When you mentioned the place with missing bits of skin - do you mean the slightly squiggly line? That looks just like the remainder of a very ancient scar. Very shallow. Not even noticeable until you mentioned to look for it. I hope you'll learn to like your face more.
I could hug you for answering me so quickly. Thank you for wading through all the info.
Do you feel it is probably bad to continue using these at the same time, if they create this reaction? (I suspect it is.)
I don't want to pester you - but do these ingredients in the Aqua Glycolic Shampoo and Body Wash (14% AHA) sound like they might mix better with the zinc oxide? There's no sodium lactate in it - and it has ammonium glycolate instead of hydroxide.
I don't have anything useful to add to your post, but I just wanted to applaud your dedication to researching things carefully. I will keep an eye on this topic and see if there might be more uncovered. Even if you don't get replies that can add to your research, I hope you'll keep trying. Thanks for helping others while you're helping yourself.
