removing pimple scars?!

So my skin is pretty weird, when I was younger I used to have bad eczema all over my body but now as I've grown older (I'm 16) it's pretty much gone. My skin on my face used to be but over the past 2 years it's gone insanely dry. So dry that when I get out of the shower and dry my face in less than 1 minutes my skin will have visiable flakes of dryness. 
Anyway so when I'm on my period or when my hormones are raging I get a few spots (as I'm sure everyone does) but when i was younger I just used to pop and pop until it left scars. I now have lots of dark patches where my scars are on my chin from those spots. Most scar treatments dry out my skin super badly so I'm just wondering if there's any products (cruelty free please) or home remedies that aren't drying but can remove scars? Thanks😊
