Dermaroller / Microneedling


This is a minimally invasive technique using a micro-needling devise (most commonly derma roller) to cause controlled skin injury. Derma roller is a small handheld roller with needles of varying number & size.

Indications for micro-needling

  • Reducing scars due to pimples/trauma/other reasons
  • Skin wrinkling
  • Stretch marks
  • Prominent pores
  • Mechanism of action

    As needles penetrate skin, there is creation of a multitude of tiny puncture wounds to the dermis (middle layer of skin) leading to secretion of growth factors that stimulate the production of new collagen and elastin (proteins of dermis).

    Creating dermal damage without the removal of healthy epidermis means that healing time is rapid and does not cause any comparable pain.

    Procedure:

    A topical anaesthetic cream is applied to area to be treated so that area becomes numb, minimising any discomfort. It takes 30-45 minutes to numb the area.

    The doctor then applies the derma roller to your skin, moving it in a series of rhythmical strokes, up and down your skin. It takes around 20 to 30 minutes on average. This causes tiny wounds, the number & depth depending upon derma roller used.

    There may be some reddening of your skin following this procedure, with skin looking like mild sunburn. This will become normal within few hours. Doctor will prescribe a mild cream or soothing gel to your skin which will help to ease any discomfort as well as keeping your skin smooth and supple.

    Post procedure care

    Micro needling is well tolerated by patient but erythema may be seen after treatment, lasting for 2-3 days. Strict photo protection for a week is advised as a routine and local antibiotic creams may be prescribed. The patient can go back to work the very next day.

    Apart from erythema, no other side effects have been reported. As the micro holes close immediately, postoperative infections do not occur.

    Advantages

    The procedure is :

  • well tolerated and well accepted by the patients
  • cost-effective
  • can be done on all skin types
  • Can be combined with other acne scar treatments like subcision, chemical peels, microdermabrasion, and fractional resurfacing, thus maximizing the benefits to the patients.
