I don't support chemical usage on face.
Exfoliating helps with you with this. Since you have sensitive skin, use baking soda ! Or you could try tomato slice with sugar and do circular motions, but it might be too harsh for you. Also mix up water with lemon juice and let it work over-night ! Patience is important with these problems.
It took me around 4 years for my cheek scar to heal and that including the lemon juice and exfoliation I did in these years !
About the sun thing. Tanning actually helps my acne and scars to fade away for a PERIOD ! After the tanning is gone I breakout alot.
The only two things that can help you reduce the scarring is exfoliation and patience.
On its simply healing it could take months even decent years before the scar is gone.
And the sun thing, well, you can't do much about it. Use sun protection lotion or try to avoid the sun as much as possible.
Well today I feel quite weird, I have little pimples everywhere, not noticeable but I don't know, my face looks dirty and ugly ... Not to tell that my iritation is getting worse, I see little white skins falling from it, I have no clue what to do about it, I have it for almost one month !
Hey, I'm new here and wanted to share my state at the moment. I can see some little pimples growing on my forehead, some little white ones on my cheek , a little red spot near my mouth and my 3 week iritations. As usual for today.
