What's best for acne scar fillers, Bellafill vs Silikon 1000? Could it cause an embolism for shallow filler technique? (photos)

Hello! We do not use Silikon 1000 in our skin clinic.  Bellafill is an FDA approved permanent injecatble filler for the correction of nasolabial folds, or smile lines. Remember, Bellafill is a non-resorbable dermal filler, so does not typically need multiple infections like the other fillers out there. Bellafill is also approved for the correction of moderate to severe facial acne scars on the cheeks in patients over the age of 21 years. It is a wonderful product and I would suggest consulting an expert in your area. Ask to see before and afters of their clients. Best of Luck 

Even with shallow depths, there is a very tiny chance of arterial occlusion. The filler of choice will depend on the skill sets and comfort level of your dermatologist or plastic surgeon. In the context of Bellafill, Dr Steve Weiner in FL is one of the best for this filler in the States. Your scars will require more than just filling- subcsion ideally needed during or pre filler. 
Acne scar revision is a sub-specialised field. For the best results, one should target the acne scar type with ideal treatments and not just one device. The web reference below will take you to a resource to help you understand acne scar revision at a specialist level. I embedded all the videos in one page to help. 
For example deep ice pick scars, and narrow box car scars can be treated with TCA CROSS peels, mixed scars, rolling, and atrophic scars treated with fractional devices such as Fraxel, fractional lasers, PRP and INFINI radiofrequency. Atrophic scars (depressions) can be treated with either fat grafts, or with HA dermal fillers. Tethered and anchored scars are best treated with surgical techniques such as subcision. Other surgical techniques that we use include punch elevation, surgical elevation, punch excision and traditional excision of focal scars. 
The majority of patients will have a collection of different scar types, and hence a tailored treatment METHOD will be best. Careful examination, especially under angled lighting with scar mapping will give you an understanding of what are the best options for your scars. In the majority of patients its finding the correct combination that give you best results, and everyone is unique! All the best,
