Acnexel:
- This treatment does not penetrate as deep into the skin as the other 2 treatment modalities. It is probably more suitable for skin conditions that do not require intense treatments such as pores but not for scars.
Microneedle RF / CO2 laser:
- These 2 treatments are suitable for acne scars and does penetrate deeply into the deep skin layer to break up the thick fibrous scar bands. I do prefer using the CO2 laser first depending on the type of scar although it is more intense and have a longer downtime. Each does has its' pros and cons and should be discussed with your doctor before proceeding with the treatment.
As Dr Justin has mentioned, other treatments such as Subscision and TCA CROSS will also have to be considered as you have a combination of scars.
Hope this helps.
All the best!
