Derma Roller + After Q&A

Can we use alpha arbutin with hyaluronic acid after derma rolling?

I'm using 0.5 derma roller and I first faced burning sensation then redness of the skin and next day I got small tiny bumps. How to get rid of those bumps? 

Can you please explain if we can use resveratrol and ferulic acid after microneedling at home?

After the using of derma roller I washed my face with cold tap water to avoid a burning sensation. I also applied Vitamin E on face but I still have burning sensations

I just done dermarolling 3 days ago using 1mm.

I've been dermarolling my face and neck for 2 years. My neck looks terrible. Worse than before I started. Is this from dermarolling and how can I fix this? Help!

It is safe coconut oil and vitamin C capsule oil after derma rolling at home because the serum is not suiting me?

I accidentally used salycilic acid 2% after derma rolling acne scars 0.5mm needle. What adverse effects will occur? And can they be reversed. I was gaining good results from salycilic acid itself but randomly decided to derma roll. I dont want the progress to be reversed. 

I just used a .5mm derma roller and applied aloe vera gel from The Face Shop after a few minutes. As soon as I put the aloe vera gel on my face, my face felt a stinging sensation. Did I do something wrong? Am I not supposed to put aloe vera gel right away?
