What are the effectiveness and risks of fat-melting injections offered in local aesthetic clinics?

It is perfectly safe to perform subcision treatment to your skin with prior CaHA fillers injection at anytime. Filler injection can be performed right after a subcision treatment for depressed acne. Subcision works well for rolling and boxcar acne scars as it breaks fibrous bands tethering the surface skin to the deeper layers. The fillers help to lift the skin up, preventing further scar formation around an indented area again. Biostimulant dermal fillers such as Radiesse, Ellanse and Sculptra are good choices of products.

Botulinum toxin injection on the trapezius is safe if it's done by a trained medical practitioner. Botulinum toxin type A is a neurotoxin that "relaxes" muscle through inhibition of acetylcholine release at the neuromuscular junction [1]. Botulinum toxin was first used to treat patients with strabismus by an American ophthalmologist and approved by US FDA in 1989 for the treatment of blepharospasm and strabismus [2].
