Sagging Facial Skin from Summer Heat? Ultherapy and Thermage Lifting Can Help

Intense summer UV rays and heat are a primary cause of collagen and elastin breakdown in the skin, significantly reducing facial elasticity. Especially during summer when outdoor activities increase, photoaging accelerates—and by autumn, many notice their skin suddenly appearing more sagging. Ultherapy and Thermage lifting are gaining attention as effective solutions to combat this summer-induced skin laxity.

What is Ultherapy?

Ultherapy uses MFU-V (Micro-Focused Ultrasound with Visualization) technology to deliver ultrasound energy deep into the skin. Without damaging the surface, it reaches the SMAS layer (superficial musculoaponeurotic system) to stimulate collagen regeneration. As an FDA-cleared non-invasive lifting procedure, its effects appear gradually—skin lifting and elasticity improvements continue to develop over 3-6 months post-treatment.

What is Thermage FLX?

Thermage FLX uses radiofrequency (RF) energy to regenerate collagen in the dermal layer and restore skin elasticity. The latest version features shorter treatment times and 4D vibration technology that significantly reduces discomfort. It also offers an Eye Tip applicator for delicate areas around the eyes and upper eyelids, making it effective for eye area lifting.

Differences Between Ultherapy and Thermage

The two treatments use different energies and work at different skin layers. Ultherapy uses ultrasound energy to reach the SMAS layer (approximately 4.5mm depth) to maximize lifting, while Thermage FLX uses radiofrequency energy focused on collagen regeneration in the dermis (approximately 2-3mm depth). Because they act at different depths, combining both treatments ("Ulthermage") can yield comprehensive lifting and elasticity improvements from the superficial to deep layers.

Pain Management

While effective, both Ultherapy and Thermage can be uncomfortable during treatment. Options include sleep anesthesia (intravenous sedation) so the patient comfortably sleeps through the procedure, or Entonox (nitrous oxide and oxygen mixture, commonly called laughing gas) inhalation to reduce pain and anxiety. Discussing pain management options with your physician beforehand is important.

Volume Restoration Alternatives

For those who also need volume restoration beyond lifting, alternatives such as Shurink (High-Intensity Focused Ultrasound) or Volnumar (radiofrequency skin elasticity treatment) can be considered. These can be combined with or chosen as alternatives to Ultherapy or Thermage. Consulting with your physician about each option's characteristics and trade-offs is key to selecting the most suitable treatment.

Applying sunscreen diligently is the foundation of preventing summer photoaging, but skin elasticity that has already declined can be improved through appropriate lifting procedures. A thorough consultation with a dermatologist before any procedure is strongly recommended to establish the optimal treatment plan for your specific skin condition.
