Product by polymerization of lactic acid, obtained in turn from fermentation processes generally operated by bacteria of the Lactobacillus genus.
The success of the use of this product in the field of aesthetic medicine is to be found in its interesting properties: it is a synthetic polymer but biodegradable, absorbable and immunologically inert.
Polylactic acid is also used by aesthetic doctors as a dermal filler due to its ability to effectively stimulate the synthesis of neocollagene.
More precisely, it is capable of promoting the activity of fibroblasts, the cells of the dermis responsible for the synthesis of elastic fibers, glycosaminoglycans (such as hyaluronic acid) and, indeed, collagen.
