FAQ

Honest answers

Fillers add structural volume in a defined area — they reshape. Skin boosters improve the quality of skin across a broader zone — they regenerate. You might use filler to project the chin, but a skin booster to make the skin of the lower face visibly firmer, smoother, and more hydrated. They are complementary, not interchangeable, and many patients combine them.
