Self-extracted growth factor : PRP
PRP can improve the cosmetic appearance of these smile lines because PRP contains seld extracted growth factors which is a biological stimulator of collagen induction, meaning that it enhance the renewal of collagen in our skin which start to diminish with time.

PRP therapy uses your own blood extracted, to kick start the skin collagen restoration. It can soften the lines and replenish skin thickness in the nasolabial fold. Self extracted growth factor with PRP can also result in some volume replacement as dermal fillers do to make the folds shallower.
