Juvederm / Restylane / Sculptra
Injectable gels containing hyaluronic acid (HA) — a naturally occurring substance in skin — used to restore volume, smooth deep lines, and contour facial features.
How it works
HA is hygroscopic (attracts and binds water), instantly plumping treated areas. Cross-linked HA fillers resist enzymatic breakdown, extending duration. Stimulates collagen synthesis over time.
Reported benefits
- Lip augmentation and definition
- Nasolabial fold (smile line) reduction
- Under-eye hollow (tear trough) correction
- Cheek and jawline contouring
- Hand rejuvenation
- Non-surgical nose reshaping (rhinoplasty)
