The beard roller features a head with 540 titanium needles, each 0.5mm in length. During use, these needles create micro-injuries in the skin and hair follicles, which helps stimulate collagen production. This process supports beard growth by enhancing blood circulation and keratin synthesis. The 0.5mm needles gently puncture the skin, naturally promoting the production of collagen, keratin, and elastin. The roller is ideal for facial skincare when used with serums containing hyaluronic acid, vitamins, or retinol. It can also be used on the scalp to support healthy hair and improve the appearance of scars, acne marks, wrinkles, and pigmentation on the face, neck, arms, and back. Designed for control and precision, the beard roller has a compact and ergonomic build. Equipped with a microneedle head attached to durable hinges, it allows targeted application on the cheeks, sideburns, and mustache area. Its optimized design helps enhance beard thickness, density, and strength. This tool can assist in maintaining beard and skin health as part of a regular grooming routine. It also makes a practical personal care item for others. Instructions: 1. Cleanse the face thoroughly. Disinfect the titanium microneedle roller by holding a disinfectant spray 10–15 cm away and applying 2–3 even sprays. Allow it to dry for 20 seconds. Gently roll over the desired area approximately 10 times in different directions. 2. Apply a beard growth serum and massage into the skin until fully absorbed. 3. Use a clean comb to groom the beard while massaging to help the product penetrate more effectively. Regular use may help support skin regeneration, reduce the appearance of fine lines, minimize scarring, and promote healthier-looking hair.
