User Guide: Step 1: Get familiar with the Hydra Pen H3 Before using the Hydra Pen H3, make sure all components are properly assembled and free from damage. Step 2: Prepare your skin and serum Clean your face and apply your favorite serum. The Hydra Pen H3 is impeccably designed to improve the absorption of these products for maximum effectiveness. Step 3: Choose the Right Cartridge Comes with 22 replacement tips to meet your different skin care needs. Select the 12-point cartridge, Nano-HR or Nano-HS based on your skin goals and specific concerns. Step 4: Customize Speed and Depth The Hydra Pen H3 offers adjustable speed and depth settings. If you are new to microneedling, we recommend starting with the lowest setting. Gradually increase speed and depth as your skin gets used to the treatment. Step 5: Application of Microneedling Hold the Hydra Pen H3 slightly tilted and gently glide it over your skin. Be sure to maintain a steady motion to avoid excessive microneedling in an area. This process creates micro-channels, improving serum absorption and promoting collagen production. Step 6: Care After Treatment After microneedling, your skin may appear slightly red, similar to a sunburn, which is a normal response and usually fades within one to two days. Apply a soothing and moisturizing product after treatment. Step 7: Replace the cartridge Remove and dispose of used cartridge after each use. Replace with a new one to ensure safety. Step 8: Cleaning and Storage After each use, clean your Hydra Pen H3 with a disinfectant solution.
