When you were young, you really don’t know how to treat pimples unless there is someone guiding you. So, you intend to do things you shouldn’t do in the first place. Later that you realized what you’ve don’t is not the right thing. And no matter how you wish to undo things, it’s too late to.
For the scars left of your ignorance, you just need to look for acne scar removal. Because that’s the only thing to do, and that’s the only right thing to do as well. There are many ways though hope that it will be appropriate to your skin, and I’m still looking for what fits me either.
