How effective is fractional Co2 laser vs Infini RF for acne scars?

Doctor's Answer

I have been offering both these treatments in my clinic for years, and this is a question I am asked almost daily!

Both fractional CO2 lasers and Infini microneedle rf are great treatments for acne scars. I will explain how both work, and how I choose the appropriate treatment for each of my patients.

Fractional CO2 Laser

How does it work?

Fractional CO2 Laser works by ablating or burning away certain parts of the skin while leaving other parts of the skin untouched. The ablated skin will be stimulated to grow new skin and collagen. Other areas of skin is spared to reduce the downtime and allow faster healing of the skin. Overall results is smoother, younger skin with improvement of the acne scars.

Any side effects?

There will be swelling and redness of the skin after the treatment. Scabs may also be seen on the skin over the next few days. Moisturisers, Sunblock and sun avoidance are essential to prevent skin pigmentation after treatment .

Infini Microneedle Radio Frequency (RF)

How does it work?

The infini microneedle will pierce through the surface of the skin and release rf energy below the skin surface. As the needle is insulated, only the tip of the needle will release rf energy, thereby reducing damage to the skin surface. The needle can also be adjusted to reach different depths of the skin, thereby treating acne scars which may be at different depth. The rf energy will stimulate collagen and reduce the acne scars below the skin surface without damaging the skin surface.

Any side effects?

Infini sounds like a staple on your skin! Treatment is more uncomfortable compared to CO2 laser as there are microneedles used. There will be some needle marks or bruises post treatment. Scabs may be seen on the skin post treatment. Proper skincare is needed to prevent infections. Acne outbreak may occur post treatment and prophylactic treatment may be needed. However risk of post treatment pigmentation is much lower compared to CO2 Laser.

How to decide

1. Severity , type and depth of acne scars

Generally CO2 lasers are better for superficial and mid level rolling or box scars.

For deeper and scars of different depths, Infini will give better results.

Your doctor is the best person to decide on the ideal treatment after assessing your skin.

2. Tolerance

Some dislike needles and find the infini treatment painful. Rest assured that local anaesthetic cream and injections are used prior to treatment to reduce any discomfort. But with the better results from a single session of infini, the discomfort is definitely worth it!

3. Budget

Fractional CO2 Laser is cheaper. However , more sessions of CO2 lasers are needed compared to infini to achieve almost similar results.

4. Expectations

Results from one session of infini is equivalent to several sessions of fractional CO2 Laser. It is best to discuss your expectations, budget and pain tolerance with your doctor before deciding on the appropriate treatment for yourself.

Hope the above info helps!
