For acne scar treatment, is there typically more improvement in the first or last few treatments, and how much % improvement can I expect after each session?

Doctor's Answers 2

Subjectively, most of my patients report more perceptible improvement after the 2nd-4th treatment sessions if typically they undergo treatments spaced 1-2 months apart.

This corresponds to the new collagen formation stimulated by the treatment which starts about 1-2 months after each treatment and tapers off 4-6 months after treatment assuming no further treatment is performed.

8-15% improvement is to be expected after each treatment.

After about 4-6 treatments, results generally start to taper off although a small group of my patients continue to observe improvement beyond the 6th treatment.

Acne scars should improve with each treatment session and personally I do expect to see a 20% improvement with each session.

That being said, other factors that have to be taken into consideration would be whether each scar type is being treated optimally with the most appropriate treatment method as each scar type do respond differently to different treatment methods, machine settings etc.

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.
