What are the best non-energy-based (laser and RF) acne scar treatments in Singapore?

Doctor's Answers 1

In general, all effective acne scar treatments are based on inducing controlled injury to the dermis (where the scar tissues are located), which then sets in motion a healing process leading to gradual improvement of the acne scars.

As such, energy-based devices (laser, RF) have proven themselves as the preferred options for acne scar treatment as they are effective and safe.

Non-energy based treatment options are generally considered as secondary options as they are less effective or are restricted in usage. They include:

  • Microneedling (e.g dermroller) which induces mechanical injury to the dermis and works for boxcar type scars.
  • TCA Cross which induces chemical injury to the dermis. This technique is limited to the treatment of ice-pick scars only.

Is it possible to get rid of acne permanently if one has PCOS?

Yes, you are right in that acne scar treatments should be commenced once acne has resolved and become quiescent. Acne scar treatments such as fractional CO2 laser can also cause scarring if there is active ace and secondly; ongoing acne can cause new scars to form. PCOS is a condition that troubles many when it comes together with acne as the local skin factors are also affected by systemic hormonal issues. Besides oral contraceptives, anti-adrogenic medications like Spironolactone can be helpful.

How many acne scar treatment sessions do I need for mild acne scarring before I can achieve significant improvements? (photo)

Hi there, One session of Picosure will give you noticeable results of 5-10% improvement with no downtime. PicoSure utilities the Focus Lens which targets the laser energy at 20x the usual strength deep under the skin, WITHOUT removing the top layer of the skin. Therefore it has no downtime. It is also proven to produce noticeable collagen at the areas where the scars are. For moderate improvement, I suggest that you will need 5-6 sessions of Picosure.
