KOI BEAUTYProfessional Derma Stamp, Adjustable Microneedle Stamp Microneedling Pen Stamp Derma Manual Pen, 140 Micro Needling Stamp Roller for Men Women - White

It works and my skin has noticeable results since using for a month now

I have seen improvements with this stamp

This is a very good stamping device. It's made from titanium, and it certainly does the job.For anyone that's looking for a stamp rather than a roller, it should be a good choice.

So far so good ! I'm glad i bought this for my scalp hair re-growth journey . Doesn't pull my hair out like my derma roller. Neverless I'm excited to see the results.

I order things for specific reasons and they didn't show up for me. No protection cover for the stamper and that's important to me for storage and sanitation

Love this! I used to use a dermaroller but had to give this a try. It’s great at stimulating collagen without “ripping” your skin like the roller did.

False advertising... needles are way shorter in actual product... see my photos and compare to their photos. They are almost nonexistent. Very very very disappointing.

It works I think... I am nervous using the full length so i generally only use it at one millimeter it hurts some and feel a little stinging but not sure how hard i am supposed to push and don't want to hurt myself. so i use it lightly on my beard and scalp so i hope it will help me grow my hair more full and thicker.
