4. Fill the Derma roller Reservoir

• Choose a Serum or Cream: Select a serum or cream suitable for your needs (e.g., hyaluronic acid, vitamin C, etc.).
• Fill the Reservoir: Fill the derma roller reservoir with the chosen product. It is advisable to fill only half to avoid wasting the serum or cream if not used entirely.
• Verify: Ensure the reservoir is properly closed and the plunger works so that when pressed, the serum or cream is distributed through the needles.

5. Using the Derma roller

• Divide the Area into Sections: Face: forehead, cheeks, nose, chin, head. Body: arms, abdomen, etc.
• Application: Start in one section: Place the derma roller on the skin (no need to apply pressure, be gentle) and, as you roll it, gently press the plunger to release the serum or cream. Vertical Movements: Roll the derma roller vertically 4-8 times in each section. Horizontal Movements: Roll it horizontally 4-8 times. Diagonal Movements: Finally, roll it diagonally (from left to right and vice versa) 4-8 times.

Ensure that you press the plunger evenly so that the serum or cream is released at the same time the needles penetrate the skin, optimizing absorption.

6. Apply Additional Serum or Cream (if necessary)

• Even though you applied the serum during the process, you can apply an additional layer of soothing serum or moisturizing cream after the treatment to enhance the effects and calm the skin.

7. Post-Treatment Care

• Avoid direct sun exposure for the first 12 hours. Use sunscreen if necessary.
• Avoid wearing makeup or applying harsh products for the first 12 hours.
• Do not wash the treated area with hot water for the first 2-4 hours and avoid touching it.

8. Cleaning the Derma roller After Use

• Wash the Derma roller: Clean it with warm water and soap to remove any residue.
• Disinfect: Soak it again in alcohol for 2-5 minutes.
• Clean the Reservoir: Ensure that the reservoir and plunger mechanism are thoroughly cleaned and dried.
• Allow the derma roller to air dry and store it in its protective case.

9. Frequency of Use

• 0.25 mm - 0.5 mm: Can be used 2-3 times per week.
• 1 mm: No more than once per week.

By following these steps, you will maximize the effectiveness of your treatment using a derma roller with a reservoir for serum or cream, ensuring that the product penetrates directly into the deeper layers of the skin as the needles perform microneedling.
