quotPretox 20 50ml Injection Free alternative to Botulinum Toxin treatment, this Muscle Relaxant Gel is in a Liposome Delivery System. Pretox 20 is double the strength of Pretox 10. Muscles contract when they receive a neurotransmitter release from a nerve. Like Botulinum Toxin A, Pretox releases the amount of nerve stimulation on the local muscle tissue being targeted but unlike Botulinum Toxin A, Pretox does not paralyse the muscle completely. Instead it gently and temporarily reduces the strength of specific muscle contractions thus the formulation of new lines and wrinkles in reduced and old lines appear much less prominent leaving you with smoother younger looking skin. quot
