With regards to your questions:
1) Acne scars
There are different types of acne scars and most of the time, patients often have a combination of scars.
A consultation / examination is key in determining the type of scars that you have and the treatment options relevant to those scars.
Treatment options available include: subscision, fractional skin resurfacing, microneedle Radiofrequency, dermal fillers etc.
The redness associated with the scars can be improved with certain types of lasers.
2) Pigmentation
There are many different types of pigmentation and an examination is once again required to determine what type of pigment you have as this will guide the treatment required.
There are several options available but in general, lightening creams and pigment lasers are commonly used.
Moles can be removed either by ablative lasers, cautery, surgery etc.
Hope that helps.
All the best!
