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!
