Bellafill is a great treatment for specific acne scarring. It is a longer term filler with a 5 year indication. However, Co2 laser is great for acne scarring and can also help with any post inflammatory hyperpigmentation that may be left from old scarring. I would suggest scheduling a consultation with a provider to determine your specific needs. Once your scarring is identified, that will help in determining the best route to take as far as treatments go. All in all, fillers such as Bellafill can be a great option but you may be better suited with a laser to treat all factors associated with your specific type of scarring.
