Hi, There are several effective treatments for acne scars, the choice of which depends of several factors which include: type of scars, effectiveness vs side-effects/downtime, expertise, costs, etc. Current treatments include fractional laser, fractional RF, subcision, scar excision and TCA-cross. In general, deeper scars tend to improve less compared to more shallow scars, more severe scars will require more effective modalities albeit more potential side-effects and downtime, a combination of acne scars will probably benefit from a combination of treatments.

Hi, The dose of botox should be tailored to the desired response while factoring safety and the avoidance of unwanted side-effects such as droopiness, excessive muscle paralysis rather than the treatment sessional number. In my experience, fewer units of botox are required for some patients after repeated treatments as the original muscles treated decrease in bulk and strength. Your preferred aesthetic doctor will be able to assess your response from previous treatments and advise if higher doses are needed to optimize your clinical results.

Hi, Small depressions from milia extraction will generally improve over the next 6-12 months due to collagen remodelling after injury. If they remain after this period, the persistent scars may be improved by resurfacing procedures such as fractional lasers and fraction RF devices.
