I have moderately severe sunken acne scars, and I read that microneedling has been used for a very long time and is proven to be effective. In your opinion, is microneedling/dermarolling (combined with a good stem cell serum like Calecim) a good alternative to fractional lasers / radiofrequency resurfacing method if budget is a concern? I have done 5 fractional laser sessions before, and it just makes my skin thinner and increasingly more sensitive, plus cost is also an issue. 

DOCTOR’S ANSWER (4)

Dear jinnywong1,

Sunken acne scars are also known as atrophic acne scars. These are shown to benefit from two main types of procedures:

1. Skin resurfacing (microneedling, fractional radiofrequency, various fractional lasers)
2. Subcision with or without fillers and biostimulators 

I would suggest a proper assessment by an experienced doctor who is familiar with all these options, especially if you have never been offered them before. Sometimes, a single session of subcision can help more than multiple sessions of skin resurfacing, and hence be much more cost saving. There are also various fractional lasers that have different effects for different scar types. 

I agree with Dr Justin that fractional radiofrequency can definitely help more than microneedling (even with good stem cell serums), and I own a fractional radiofrequency device at my clinic too. However, this device may not be suitable for all scars. It is useful for rolling scars, and other devices are still required for different scar types. Fractional microneedling also break the top layer of the skin and can cause increased downtime if used to deep depths, higher risk of infection/acne and also increased sensitivity initially (just like lasers).

If you have deep rolling or box scars, fractional non-ablative lasers like the erbium-glass laser are a proven better option than fractional radiofrequency according to this study (Comparative study on efficacy and safety of 1550 nm Er:Glass fractional laser and fractional radiofrequency microneedle device for facial atrophic acne scar.) A proper assessment is still crucial before any treatment.

It is a misconception that lasers make the skin thinner and more sensitive. If done appropriately and with proper rest intervals, lasers increase the thickness of the skin and can even decrease skin sensitivity. Similar to fractional radiofrequency and microneedling, the skin can be more sensitive during the initial healing phase, so proper post-care is also important.

Hi Jinnywong 1,

Microneedling can be an alternative treatment since you are increasingly getting more sensitive to fractional CO2 laser. However it must b known that you ma need many more treatments and it may not be as effective for deeper scars. In my personal opinion, I do not think the cost will be a lot lower given the more sessions you may need but if sensitive skin is a major concern, then yes it can be an alternative treatment.

Although fractional CO2 laser does not thin the skin, it certain can make your skin more sensitive in some cases. The way to overcome that is not to do the fractional CO2 laser too closely and give enough rest time in between. The other important thing to note is the aftercare after fractional CO2 laser is of paramount importance in avoid or reducing the chance of sensitivity. The power and level of fractional CO2 laser is also very important and depends on the expertise of the doctor in knowing how sensitive your skin is and what you will be able to handle for optimal results and yet with good safety magin.

From the thousands of fractional CO2 lasers done, I have only seen a small handful of patients getting sensitive and proper counseling, intervals of treatment and power used is very important. 

Other alternatives to scar treatment includes subcisions (for the brave ones) and dermal fillers. I do not think there is a place in fractional radiofrequecy as the results are poor and I have seen the trend died almost as quickly as it appeared. Buying some of these machine is a watse of money and I think if we have a useless machine, we should just write it off instead of passing the cost to patients. As such if you think of price, its certainly not even cost effective as well.

Hope that helps.

Thks

Dear Jinnywong,

Micro-needling gives good results for superficial acne scars over multiple sessions. However, it is unlikely to give good results for deep acne scars. 

For deep/severe acne scars, you would still need Fractional micro-needling Radiofrequency, like Infini, which can deliver RF energy to depths that Fractional CO2 cannot reach. Devices like Infini can deliver RF energy up to depths of 3.5mm, whereas Fractional CO2 delivers energy up to 1mm deep.

Please consult a doctor for a more detailed discussion. Hope that this helps!

Warmest regards,

Dr Justin Boey

Hello Jinnywong

Microneedling has been used for a long time but it is probably not enough to treat moderate to severe sunken acne scars. 

The best acne scar treatment really depends on the type of scars you have 

  • Ice pick - TCA cross
  • Tethered scars - Subcision 
  • Box/ Rolling scars - Fractional laser resurfacing/ Microneedling RF 

If your scars are predominantly ice pick and tethered rolling scars, you can expect improvement with just a few sessions of TCA cross and scar subcision. This will usually be cheaper than a few sessions of fractional laser/ microneedling RF. Consult a doctor to get an accurate assessment first before proceeding. 

Hope this helps!

Regards

Dr Jiwei Wu
