Hi Xiu Lian,
Ice pick scars have a very narrow top and go deep. Because of that, traditional laser techniques are ineffective at targeting the depth of these scars to promote scar remodeling.
More effective methods include non-surgical options such at TCA Cross - the use of minute amounts of very strong TCA Acid deposited at the depth of the scar to promote collagen remodeling and scar resurfacing. When the scar has become less deep, subsequent laser sessions can further promote proper resurfacing.
Quicker, more invasive options include punch excision of these scars. Here, the scar is excised and the wound closed. Treatment is more definitive and quicker, though more invasive.
Improvement of scars in general from lasers/peels/radiofrequency typically have a quoted improvement of 50-70 % after 4-6 months of treatment, though improvements of up to 80-90% are possible.
While surgical removal of scars do provide better results, the final result will also depend on the healing of the wound left by the closure of the excision.
Do feel free to arrange a proper consult for a more thorough discussion on your needs and expectations on the issues you have.
Best Regards,
Dr Shane Tan
