PDLLA belongs to the wider group of biodegradable polymers: once in the tissue, the particles are gradually catabolised, and this slow breakdown is used to encourage the skin to build its own collagen. REGEN Biotech adds that the gel occupies the treated area on injection and keeps that starting volume for some time. Since the material degrades, nothing non-degradable stays behind and no surgical removal is involved. Where it is used According to the manufacturer, Aesthefill is intended for facial wrinkles and folds, for areas where facial volume has been lost, and for work on the proportions and contour of the face, including the cheeks. Because collagen stimulation develops gradually, treatments are usually planned as a course by the treating practitioner. Related products can be found among our collagen stimulators.
