Suits those who want lasting volume over an immediate change.
Placing the particles lets them dissolve slowly so the skin builds its own collagen. It comes as 120, 240 and 365 by the amount per vial, and the larger amounts are used to build volume deeper down. The effect appears from 4–6 weeks, on a different timeline from filler that fills immediately, and it lasts a long time.
It is done in about three sessions at four-week intervals. Change shows from four to six weeks and fills over one to three months, which is how long the skin takes to make collagen as the particles dissolve. Keeping the interval lets each response settle before the next accumulates.
