Koi Beauty Derma Roller, 540 Titanium Microneedling Roller, Microneedle Roller - Matte Texture Micro Needling Roller for Men Women

Best little line of rollers. Various lengths. 540 pins on this wheel size is perfect for maximizing effectiveness, minimizing hair grab, great maneuverability, while still covering enough surface area to take care of business quickly. Wider rollers just don't work as well in all the aforementioned areas. Plus it puts the cost in the right place, sharp titanium pins and a smooth roll. Inexpensive and the best. I bought two other model sizes along with this one, and then two other brands, including one that's 5 times the price of the Koi, and the Koi is functionally the best by far. Pro tip, buy a can of aerosol spray alcohol to quickly sterilize the roller before and after use. Two half second spray bursts covers and saturates the whole wheel. One of a few hair routines out there that really does stimulate growth and thickness, especially with a good topical serum/prescription creams or oils.

I originally bought the Koi Beauty Derma Roller to help with hair thinning, and it has honestly exceeded my expectations. The roller feels sturdy, well‑made, and the needles glide smoothly across the scalp without scratching or causing discomfort. It’s gentle but effective. After using it consistently, I’ve noticed my scalp looks healthier and my thinning areas don’t look as sparse. My hair products absorb better, and I’m starting to see new baby hairs along my part and hairline. It’s not a miracle overnight fix, but the gradual improvement is real. I also appreciate the hygienic packaging and the overall quality — it feels like a professional tool at a reasonable price. If you’re dealing with thinning hair and want something to support your routine, this derma roller is absolutely worth trying.

Got it for my husband for his beard growth journey, he loves it amd uses it 2 times per day. The roller is very sturdy and well-made, and the matte black finish gives it a sleek, premium look. He says it isn't harsh on the skin at all. sanitize it properly before and after each use and follow the recommended routine, it’s a great addition to your skincare regimen. Very happy with the purchase

I honestly didn’t expect to like this derma roller as much as I do. I’ve tried a couple of cheaper ones in the past, and they either hurt too much or felt flimsy. The Koi Beauty Titanium Microneedle Roller is completely different — it feels solid, rolls smoothly, and doesn’t snag on my skin at all. I started using it twice a week after cleansing my face, followed by my regular serum, and I can already tell a difference. My skin looks brighter and feels smoother, and I’ve noticed my skincare products seem to soak in better. I even think some of my acne scars have softened a little. I do get a bit of redness right after using it, but that’s totally normal and goes away within an hour or so. I always make sure to disinfect it before and after each use. Overall, I’m really happy with this roller. It’s well-made, easy to use, and gives visible results without spending a fortune on spa treatments. If you’ve been curious about microneedling, this is a great one to start with!

The product is okay in terms of softness, but it doesn’t feel as comfortable as expected. It works fine for basic use, but there are softer alternatives available. Overall, average performance.
