How microneedling works
A microneedling device (most commonly a motorised pen-style device like the Dermapen) creates thousands of controlled micro-channels in the skin using fine, sterile needles. These micro-injuries are invisible to the naked eye but are sufficient to trigger the skin's wound-healing cascade — a process that releases growth factors, stimulates fibroblasts, and results in new collagen and elastin production over the following weeks.
The needle depth is precisely adjustable from 0.25mm (superficial, for general rejuvenation) to 2.5mm (deeper, for acne scarring and significant laxity). The appropriate depth depends on the treatment area and skin concern — the face has varying thickness in different regions, and Dr Bangalee adjusts depth accordingly.
What microneedling treats
Microneedling is highly effective for acne scarring (particularly atrophic or depressed scars), enlarged pores, rough skin texture, fine lines, early skin laxity, and stretch marks. The new collagen produced fills in depressed scars, tightens pores, smooths surface irregularities, and firms the overall skin structure.
It is also used as a delivery vehicle — the micro-channels created by needling allow active ingredients (vitamin C, hyaluronic acid, growth factor serums) to penetrate far more deeply than they would through intact skin, amplifying their effect. This is used at Star Aesthetic Centre to target specific concerns alongside the collagen-induction benefit.
Treatment, recovery, and results timeline
A topical numbing cream is applied 30–45 minutes before treatment. The microneedling procedure itself takes 30–60 minutes. Immediately after, skin appears red — like a mild to moderate sunburn — which is the expected inflammatory response. This typically resolves within 24–48 hours. No heavy exercise, steam, or swimming for 48 hours.
Collagen production peaks 4–6 weeks after each session. The full impact of a course of treatments continues to improve for 3–6 months after the final session. Most patients require 3–6 sessions spaced 4–6 weeks apart for optimal results on acne scarring; general skin rejuvenation often achieves excellent results in 2–3 sessions.
