  • Acne scars are the long-term visible sequelae of more or less severe active acne.
  • The demand for its treatment is in our experience is quite high and reaches 20% of those who had treatment for active acne…even though its treatment is considered cosmetic and is therefore not covered by medical insurance.
  • Treatment options include topicals (adapelene), chemical peels, lasers (fractionated and ablative), dermabrasion, subcision…and many more
  • Dermal needle technique consists of small needles fixed on a sterile roller (dermaroller) to puncture the skin.
    • Needles are 1,5 to 2mm in thickness and traumatize the dermis.
    • The resulting microbruising, induces wound healing t¥which ends up in the production of collagen – and therefore act as “fillers” to the lost volume

Acne scars microneedling: before and after

  • Author recommendations:
    • Results are seen 6 weeks-3 months after the treatment
    • 3 to 5 treatments are recommended spaced each by 4 weeks.

 

 

Methods

  • inclusion of 10 patients (5male and 5 female) (19-48 years old, mean age 31 for females and 26 for males)
  • 3 needling treatments each spaced by 4 weeks
  • treated scars were generally boxcar and ice-pick scars
  • photographs were done before and after treatments

 

 

Results

  • Patients reported a 60% improvement in overall scar appearance

 

 

Conclusion

  • No single treatment is simple and definitive and dermal microneedling is actually another treatment option.
  • The full result may take 8-12 months to be optimal, and this corresponds to the maturation of scars of the wound healing process.
