When you first hear about rolling tiny little needles all over your face, your initial reaction may be one of horror and disgust. And with good reason - at first glance, a derma roller does look rather suspiciously like something from a horror movie. But guess what? These frightening-looking devices can actually do wonders for your skin.

The needles in question have to be uber tiny - 0.25mm, to be exact. This means they don't really penetrate the skin, but instead stimulate its surface. This can help the skin to repair itself more quickly - meaning micro-needling can be a super effective treatment for scars, discoloration, uneven texture, and wrinkles. But even if you aren't troubled by any of these skin concerns, it can also help give your skin a post-facial glow.

And now, you can achieve these results at home. The Sdara Skincare Derma Roller is currently on offer on Amazon - and the reviews speak for themselves.

"Just so you know, I had the micro-needling done at a $300 pop with 3-inch needles. I bled through this procedure which they say you're supposed to and it wasn't painful until they went over the same areas again and then it was really hard to take. For 3 to 4 days my face was full of red spots and I wasn't allowed to put anything on my face. I vowed I'd never go through that again. When I saw a video on this product my first thought was 'with a .25mm I could do this myself.' This is my new glam product and I can definitely see a difference in 3 weeks than I did with the $300 one. I only use it once a week and I can either give more pressure or less depending but thank God no blood, no red spots, and whatever redness happens, it's gone in a few hours. So I do it every Sunday evening. I love this product," writes just one of the 20,000 5-star reviewers.

Even better? This roller is approved by dermatologists, too. "I like this device," Dr. Rachel Nazarian, MD, FAAD, told PEOPLE. "It's a classic dermaroller." She recommends using it "on recently cleaned, dry skin. Make sure that the device itself is also recently cleaned with alcohol, and then go either in an up-and-down or side-to-side motion; you can alternate between the two." She also advises you should "apply very gentle, even pressure, trying not to break skin or puncture the surface."
