I think I understand better now. Thanks for explaining.
Years ago, when I was NOT on birth control, I came here seeking answer too. I found that benzoyl perodixide, sal. acid, and other often used products gave me severe reactions. I'm horribly sensitive and allergic to many things. (since then found out I have a variety of skin probs - not just acne).
When I went on the pill (I know this isn't an option for you) I still needed help with my skin - and that's when I discovered the benefits of a topical daily AHA and moisturizer. It takes dedication and time for the results to happen however. If you're impatient, and want results to show up in a week or two, don't try it. It takes probably 6-8 weeks for it to start working well. It may purge you during those weeks. It has to be started slowly, or you may get red, irritated, itchy, etc. If you start it, do it every other day or less to begin with. I worked up to twice daily - which was my perfect amount - using a 10% glycolic. My routine was just this: Wash twice daily with cetaphil gentle cleanser. (comfortably warm water - pat dry) Let the skin dry for a few minutes. Put Cetaphil Cream moisturizer on face. Let it dry at least 5 minutes - or up to 30 minutes if you have the time. Then apply the AHA. (Waiting to let the face really dry helps curb possible irritation when you're not used to the product.) That might be all you need to get rid of the dryness and help keep the pimples from forming. Not sure if it does much with oiliness, but it doesn't make it worse.
That was all I needed for MANY years. Coming off the pill just recently has changed my hormones and the AHA doesn't do it all by itself anymore. So I'm using other things in combo with it - with some help from my derm (who I don't totally trust yet.) My derm loves AHAs, so that's a bonus that she didn't pry it out of my hands.
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.
