Micro-needling devices — dermarollers or growth rollers — create temporary micro-channels on the skin's surface that improve the skin bioavailability of topical active ingredients applied immediately afterwards. This approach is documented in scientific literature on hair serums and concentrated follicular care.\u003c\/p\u003e\n\u003cp\u003eThe Sapiens. Growth Roller is equipped with 540 titanium microneedles 0.5 mm deep. This depth allows it to reach the superficial dermal layer and stimulate local microcirculation, promoting temporary vascular supply to the treated area. Titanium is a biocompatible material known for its corrosion resistance and skin tolerance. This 0.5 mm format is suitable for beard and scalp use — areas with dense hair follicles. The Growth Roller comes with a Sapiens. disinfectant spray (15 ml) for cleaning before and after each use, and a storage box.\u003c\/p\u003e\n\u003cp\u003eRecommended use: apply the disinfectant spray to the needles before use. On clean, dry skin, gently roll the roller in 3 to 4 directions (horizontal, vertical, diagonal) over the beard area or scalp — light pressure only. The session lasts 2 to 5 minutes per area. Apply the active serum (PD-0512 Sapiens. Beard Growth Serum) within 15 to 30 minutes after using the roller. Disinfect again after each use. Frequency: 1 to 2 times a week maximum — do not use daily, to allow the skin time to recover between sessions.\u003c\/p\u003e\n\u003cp\u003eMandatory precautions: do not use on damaged skin, skin with wounds, active lesions, dermatitis, dermatosis, or skin infection. Do not use on moles, warts, or areas of abnormal skin. In case of pain or bleeding, stop immediately and consult a healthcare professional. Device for individual and exclusive use — do not share, even after disinfection. Needles should be replaced according to the manufacturer's recommendations (gradual wear over 3 to 6 months depending on frequency). Do not use if you are on anticoagulant treatment or have a diagnosed skin condition without prior medical advice.\u003c\/p\u003e\n\u003cp\u003eIn the Sapiens. beard routine from the Men's collection, this Growth Roller precedes the application of the Beard Growth Serum (PD-0512). The combination of the two forms the Sapiens. Beard Growth Kit — a two-step protocol. It is essential to use them in this order: roller first, then serum after a 15 to 30 minute delay.\u003c\/p\u003e","brand":"Sapiens.","offers":[{"title":"Default Title","offer_id":53846803972433,"sku":"PD-0511","price":24.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1032\/7094\/1009\/files\/Dermaroller-Barbe-et-Cheveux-Sapiens-258761567.jpg-2.webp?v=1779544025","url":"https:\/\/paradermia.com\/en\/products\/sapiens-dermaroller-barbe-cheveux-pd-0511","provider":"Paradermia","version":"1.0","type":"link"}
