I use a hyaluronic acid serum and stopped because there are too many unnatural ingredients and perservatives in it. Sodium bezoate, pottasium sorbate, ethylhexylglycerin, benzyl alcohol to name a few. I was using it to plump up my nasolabial folds but i hear only fillers do that. I want to try fillers but i don't want all these unnatural chemicals being injected deep in my skin. Do restylane and juverderm only contain ingridents that the body makes naturally or are there harmful chemicals in it?
