Meifren Derma Roller Micro Needle

How to Use a Derma Roller (Medical/Aesthetician Guidelines)

1. Choose the Correct Needle Length (based on treatment goal):

   • 0.25 mm – Enhances product absorption, mild skin rejuvenation (safe for home use).

   • 0.5 mm – Treats superficial fine lines, mild scarring, and pigmentation (semi-professional/home with caution). Best for beard growth stimulation and general hair thinning

   • 1.0 mm and above – Targets deeper acne scars, wrinkles, stretch marks (should be performed by a trained professional). More effective for deeper follicle stimulation on scalp (especially in areas with visible thinning)

2. Preparation:

   • Cleanse the skin thoroughly with a gentle cleanser.

   • Disinfect the roller with 70% isopropyl alcohol before and after use.

   • Optional: Apply topical numbing cream for needle lengths ≥0.5 mm.

3. Technique:

   • Roll the device gently in vertical, horizontal, and diagonal directions across the treatment area.

   • Apply light, consistent pressure—do not press too hard.

   • Cover each area 2–3 times in each direction.

4. Aftercare:

   • Apply a soothing serum (e.g., hyaluronic acid, peptides).

   • Avoid makeup, active ingredients (retinol, acids), and sun exposure for at least 24–48 hours.

   • Always wear broad-spectrum SPF daily after treatment.

Where to Use a Derma Roller

• Face: Common areas include forehead, cheeks, chin, under-eye area (with shorter needles), and around the mouth.

• Body: Can be used on neck, décolletage, abdomen, thighs, and areas with stretch marks or scarring.

• Scalp or Beard: for beard growth stimulation and general hair thinning
• Avoid active acne, open wounds, rosacea, eczema, psoriasis, or skin infections.

When to Use a Derma Roller

• Frequency depends on needle length:

  • 0.25 mm – Every other day or 2–3 times a week.

  • 0.5 mm – Once a week.

  • 1.0 mm – Every 3–4 weeks (ideally in a professional setting).

  • 1.5 mm and above – Every 6+ weeks, only under professional supervision.

• Time of Day: Evening is preferred to allow overnight healing and reduce sun exposure risk.

Cautions and Contraindications

• Do not use on active acne, herpes outbreaks, keloid-prone skin, or if you’re on blood thinners or isotretinoin.

• Always consult a dermatologist or licensed aesthetician if you have underlying skin conditions or are unsure about proper use.
