Sagging skin

Jawline, neck, or body laxity—collagen remodeling with RF, ultrasound, or surgery when advanced.

Overview

Skin laxity reflects combined loss of collagen elastin networks and gravity’s effects on supporting ligaments. The AAD overview of cosmetic procedures reminds patients that non-surgical tightening improves but rarely duplicates surgery.

RF microneedling and ultrasound/RF devices heat collagen to trigger remodeling over months.

Contributing factors

Chronological aging, photoaging, major weight changes, and post-pregnancy tissue stretch all contribute.

Treatment options

Options include RF microneedling (e.g., Morpheus8), ultrasound or RF tightening platforms, and sometimes surgical referral for redundant skin. Injectable fillers do not lift heavy skin—they restore volume.

Combination protocols (skin quality + tightening) are common for jawline definition.

What to expect

Collagen remodeling unfolds over 3–6 months; multiple sessions are typical. Results vary by age and baseline laxity. Maintenance is expected.

Frequently asked questions

Usually a series of 3 or more spaced 4–8 weeks apart depending on device and area; neck often requires patience.

No—non-surgical tightening improves mild to moderate laxity. Severe redundancy may need surgery for best contour.

Disclose all implants and prior procedures—energy devices may need modified settings or avoidance over certain areas.
