Derma Roller + Age 18-24 Q&A

I am 21 years old male and have barely visible beard and I came to know about derma roller for beard growth and want to give it a try. So I just wanted to know is 0.25mm safe for me. And if yes then what routine should I follow

Gender female, I am 19, my height is 155, my weight is 52, my skin type is oily, and it has traces of grain and large pores. I used the dermaroller twice only, and once I put vitamin C serum and again Nisamide serum. Can I use vitamin E after that and anything better that I can continue to use

Gender -- male Age-19 Height-6.2 Weight --75kgs Skin type- dry skin Face skin type is oily

I am 21 years old and I have lost 20 lbs, and I am planning to lose 70 lbs more. I am aware that saggy skin will be a problem but I want to eliminate it as much as possible. I have old stretch marks above my breasts too. Is derma rolling a safe and an effective option?

Sir, I'm 20. My hair volume is decreasing. Can I use Derma Roller? I have dandruff. Is any infection caused by using Derma Roller by a dandruff person?

Hi docs, 20 year old male here, a few months ago I naively started using a 0.5mm dermaroller at home on my lips after reading about it plumping on beauty blogs. The result has been awful, my vermillion border has faded, my cupids bow has lost its sharpness/height and thinned out, I have a raised scar on my procheilon, and lips lost their red pigment, having become pale pink/white. Is there anything I can do to get my lips back to how they were before, or is this damage irreversible?

I am a 23 year old nursing student with some volume loss under my eyes and hollowing. So, I do not get puffy bags under my eyes but you can see there is volume loss.I am opting for fillers but i'd like to see if theres something more permanent and I can't spend a ton right now. If you look at my photos I attached it's not horrible or anything but it does make me look tired and bothers me.

when i was in my 2nd yr. college i have mild acne so it left scars on my face it's really heart breaking when i see my scars in the mirror. im desperate to fade all my acne scars pls. help me ( at what age can be use derma roller? or at what age can derma roller treatment start?) sorry for my english
