Loose skin is a common concern for today’s GLP-1 patients. Medications like semaglutide and tirzepatide help people lose weight faster than ever, but the skin doesn’t always keep up with the rapid changes underneath. Collagen and elastin (the fibers that give skin firmness and elasticity), can lag behind, leaving areas of the face and body looking thinner, loose, or hollowed.
At TKI, we use a proactive, non-surgical approach to help skin stay strong and youthful throughout weight loss. Our strategy combines multiple technologies and interventions to support collagen, tighten tissue, and maintain natural contours. Key treatments include:
- Sofwave™ for early collagen stimulation and firmness
- RF microneedling (Secret RF®, Morpheus8®) for deeper remodeling
- Laser treatments (Laser Genesis, fractional CO2) for texture, tone, and tightening
- Biostimulatory injectables (Sculptra®, Radiesse®) for structural support and natural volume
Together, these treatments help the skin adapt to rapid changes and minimize the appearance of laxity, so anyone can enjoy the full benefits of their weight-loss journey.
Why GLP-1 Weight Loss Changes the Skin
GLP-1 medications reduce appetite and slow digestion, leading to a rapid drop in calories. While this is excellent for fat loss, it also means the body can lose structural support more quickly than the skin can rebuild.
When this happens, patients often notice:
- Hollowing in the cheeks or temples
- Softening along the jawline
- Looser skin on the neck, abdomen, arms, or thighs
- Fine lines becoming more visible as volume decreases
Unlike gradual lifestyle-based weight loss, GLP-1 changes can outpace the skin’s ability to regenerate collagen. The good news is that this is exactly where modern aesthetic medicine excels.
How TKI Supports GLP-1 Patients
Dr. Mira Kaga and her team design treatment plans based on how much weight you are losing, how fast it is happening, and where your skin is responding.
“The most common concerns we see are hollow cheeks, sagging skin, fine lines, and muscle loss,” Dr. Kaga explains. “These are all signs that the skin’s support system is being challenged. Our goal is to strengthen that system while weight loss is happening, not just after.”
That’s why TKI uses layered, collagen-building treatments instead of one-size-fits-all tightening.
Sofwave™: The Foundation of Skin Tightening
Sofwave™ is often the first treatment introduced for GLP-1 patients. It uses precise ultrasound energy to stimulate collagen and elastin at the depth where the skin’s support network lives.
Dr. Kaga explains, “GLP-1–related weight loss often happens faster than the skin can remodel. Sofwave™ helps preserve dermal thickness and fibroblast activity, which reduces long-term sagging.”
Clients typically experience:
- Firmer jawlines, chin, and neck
- Smoother fine lines
- Stronger, more resilient skin
- Gradual, natural lifting over several months
Because Sofwave™ has minimal downtime and is safe for all skin tones, it fits seamlessly into a GLP-1 treatment plan.
RF Microneedling for Deeper Remodeling
While Sofwave™ strengthens the dermis, RF microneedling devices like Secret RF® and Morpheus8® go deeper to tighten the skin from below the surface. These treatments create controlled thermal stimulation that rebuilds collagen in the deeper layers responsible for firmness and texture.
Dr. Kaga and her team typically sequences treatments like this:
- Sofwave™ first to improve elasticity and skin quality
- RF microneedling 4-6 weeks later to remodel deeper tissue and improve laxity
This layered approach leads to more visible and longer-lasting tightening.

Laser Treatments for Tone, Texture, and Long-Term Tightening
Laser technology helps maintain skin quality during weight loss and refine it once weight stabilizes.
During active weight loss, Laser Genesis supports:
- Collagen production
- Redness and vascular health
- Overall tone and smoothness
Once weight has stabilized, fractional CO2 resurfacing can be used to address crepey skin, deeper wrinkles, and more advanced laxity for more dramatic tightening and texture improvement.
Restoring Structure With Injectables
Rapid fat loss can leave the face looking tired or hollow. Instead of simply filling the skin, Dr. Kaga often uses biostimulatory injectables like Sculptra® and Radiesse® to rebuild collagen and structural support from within.
These are commonly used to improve:
- Cheeks and temples
- Jawline and lower face
- Skin thickness and elasticity
Hyaluronic acid fillers may also be used conservatively for precise contouring once the foundation has been rebuilt.
Regenerative and Lifestyle Support
In addition to energy-based treatments and injectables, regenerative therapies and lifestyle interventions are key to optimal results.
- PRF and exosomes can be applied 24-48 hours after Sofwave™ or RF microneedling to enhance collagen signaling and support healing.
- Nutrition and exercise are essential. Adequate protein intake and resistance training help preserve muscle and support collagen remodeling, which is particularly important for GLP-1 patients who may be prone to muscle loss.
Dr. Kaga emphasizes that combining aesthetic treatments with lifestyle support maximizes both skin quality and long-term results.
Why Starting Early Makes a Difference
Dr. Kaga follows a two-phase approach for GLP-1 patients:
During weight loss (prevention)
- Early collagen stimulation
- Sofwave™ and Laser Genesis
- Nutritional and muscle-preservation guidance
After weight stabilization (correction)
- RF microneedling
- Fractional CO2 laser
- Biostimulatory injectables
Patients who begin treatment early tend to maintain more natural facial contours and need fewer corrective procedures later.
