They have been used popularly for years.  They are known for the most part as Restylane and Juvederm, and they are two of the most popular needle injection based procedures that do not actually require surgery to lift your face and get rid of your wrinkles.  They are generally minimally invasive, and they inject fillers into the area around lines, furrows, folds, scars, and skin depressions.  They don’t use botox or anything else to potentially freeze or harm or even poison the muscles.  But they fill voids and holes. 

Each filler has different ingredients.  Some are more standard like hyaluronic acid or collagen and others are something like PLLA.  The body breaks these substances down as it goes along, so you have to get them reapplied every 4 months to a year from what their websites say.  But most have complained it usually doesn’t last as long as claimed, and there are often infections, bruising, redness, swelling, pain, tenderness, rashes, skin death, blurred vision, and some have reported these fillers moving throughout the skin to sports where they were not supposed to.  930 cases of these side effects have been reported recently. 

Some have tried to say that theirs have “very low adverse event reporting rates.”  But considering the fact that they are so expensive that they have lower sales rates than say a common cream or even a common diet pill and yet those products have lower numbers of complaints and reports concerning side effects, apparently they have a very different definition than mine.
