Thermage FLX Sydney
What is Thermage®?
Thermage FLX is a non-invasive radiofrequency (RF) skin tightening treatment that may help smooth, tighten, and contour skin for a more youthful-looking appearance. Using patented monopolar RF technology, it delivers controlled heat energy to the deep dermal layers of your skin — stimulating existing collagen and activating fibroblasts to support new collagen production over time.
Think of Thermage as structured conditioning for your skin. Just as targeted exercise tones muscle, Thermage FLX works from within, addressing skin laxity at its source rather than at the surface. The result, subject to individual assessment, is firmer, smoother skin on the face and body — with no surgery, no injections, and no downtime.
Thermage FLX can help improve facial contours by softening wrinkles and fine lines, for a naturally refreshed appearance. It is suitable for all skin types and may be used across a wide range of treatment areas on the face, eyes, and body:
Face — As we age, loose jowls, a softened jawline, and sagging skin become more visible. Thermage FLX radiofrequency skin tightening may smooth and remodel dermal collagen across the mid-face, lower face, and neck — supporting a more defined, rejuvenated appearance. For patients exploring complementary options, our Facial Contouring and Wrinkle Reduction treatments may also be considered following a consultation.
Eye area — Hooding, fine lines, crow's feet, and a heavy brow line can add years to your appearance. Thermage FLX targets the upper and lower eyelids to help reduce the appearance of wrinkles and decrease hooding, supporting a more open, refreshed look. This may be considered alongside our dedicated Eye Bag Treatment, subject to your clinician's assessment.
Did you know adult skin loses approximately 1% of its dermal collagen content every year?
Collagen is the most abundant structural protein in the human body, accounting for 25–35% of total protein mass. It plays a pivotal role in the integrity of several tissues — most visibly the skin — providing the scaffolding that keeps it firm, elastic, and smooth.
From approximately age 25 onwards, natural collagen production begins to slow. As dermal collagen declines, skin laxity increases: fine lines deepen, contours soften, and the skin gradually loses its ability to rebound. To support new collagen production, fibroblast cells need to be activated — and this is precisely what Thermage FLX radiofrequency therapy is clinically designed to do.
By heating the deep collagen-rich layers of the skin to a precise therapeutic temperature, Thermage FLX triggers a remodelling response. Existing collagen fibres contract and tighten immediately, while the body's natural healing process drives the formation of new collagen over the following three to six months. This dual-phase response — immediate and progressive — means results may continue to improve well beyond your treatment day, with individual outcomes varying based on skin condition, age, and treatment area.
For patients interested in combining collagen-stimulating approaches, our Microneedling Treatment and PRP Skin Treatment may be suitable adjunct options, subject to a full clinical assessment at your consultation.
