Derma Roller + Retinol Q&A

I currently use moisturiser, retinol and hyaluronic acid to treat my stretch marks, however I am unsure if treating them whilst I havent lost weight is ineffective. I want to experiment with dermarolling for my stretch marks however I dont know whether to start this before or after weight loss. Also could you please let me know whether I should just continue the moisturising portion of my regimen and stop the retinol and hyaluronic acid until ive lost weight.

I have white stretch marks and they are not indented. Is it safe if I apply retinol serum right after dermarolling with 1.5mm dermarollers ? If not what would you recommend? Thanks in advance.

Hi there, I used dermaroller for the 2nd time after a month. I used Retinol just after dermaroller and my skin is burning. What should I do now?

So I believe I have tears in my skin on my cheek near my eye and nose from dermaroller use. It's been a month since done but lines here look very pronounced. I'm not sure if it's from rolling or possibly retinol use but skin doesn't feel or look dry just prominent lines tears. Will this improve after time or will it need treatment. Photo doesn't really show what I see when I look in the mirror but area is not smooth.

Can I use retinol and emu oil directly after dermarolling?
