I'm fairly new to derma rolling (just completed my forth session) so by no means an expert. I have researched various skin related things so here's my views & experience to help you decide what's right for you.
I single needle scars/lines then use a 1mm roller every 4wks on my face. Then copper mask & infadolan as per Sarah's instructions.
Most days I use vit c and Retin A.
Vit C is an antioxidant and Retin A is proven to reduce wrinkles. (They both do many things you can Google it & get heaps of info.)
Every few days I use Glycolic acid 10% it helps remove old skin cells and I believe like dermarolling helps with product penetration.
Mornings I use a sun screen with a moisturiser.
My skin has never looked better. I've noticed my pores getting smaller, my tiny brow lines etc getting fainter. My skin kinda glows now & is more even.
I have noticed I can't stop Retin A as lines seem to deepen. Hopefully over time with derma rolling that may change.
I try and judge by how my skin is looking/feeling as to what it needs. Like, if its flackey I will use glycol to peel it...if its dry leave it from exfolliators & use infadolan.
I don't think lasers work any better than dermarolling but more educated people can help you with that.
The only way I know of to completely remove lines (temporarily) would be Dermal fillers..restylane etc
Maybe someone who's been derma rolling for years could let us know results on this one.
What I eat affects everything....skin, hormones, mood..... its all related.
I've just started dry brushing my entire body. I think its meant to help remove toxins & thickens skin. It feels great. Maybe Sarah could start to sell a line of skin brushes "hint, hint
I've tried various creams & really feel this is best.
Hope it helps,
