35, 5'8, how do I get rid of excess facial elasticity on lower cheeks and neck? (Photos)

Based on the submitted photos you should have nice results from Morpheus8. Typically three to four treatment sessions are recommended spaced one month apart. You will continue to see results for several weeks following your treatments as new collagen is created.

Profound RF (Radio Frequency) is a minimally invasive treatment that combines microneedling with radiofrequency energy to address skin laxity and improve elasticity. Here's how it works to reduce extra facial elasticity on the lower cheeks and neck:
**Microneedling**: The procedure involves tiny needles that penetrate the skin, creating controlled micro-injuries. This stimulates the body's natural healing response, promoting the production of collagen and elastin, which are essential for firm and youthful skin.
**Radiofrequency Energy**: Once the needles are in place, radiofrequency energy is delivered deep into the skin. This energy heats the underlying tissue, causing collagen fibers to contract and tighten immediately. Additionally, the heat stimulates further collagen and elastin production over the following months.
**Tightening Effect**: The combined action of microneedling and radiofrequency energy leads to a tightening effect on the skin. The increased production of collagen and elastin helps to firm up the skin, reducing sagging and improving overall texture and elasticity.
**Gradual Improvement**: The results of Profound RF develop gradually over time as new collagen and elastin are produced. Patients typically see noticeable improvements in skin tightness and texture within a few weeks to months after the treatment. Find a Profound expert.

Cardio will not be able to tighten your skin.
Morpheus may help. Most patients see a difference 6 weeks after their second treatment and then the third session locks it into a place for a year.
You are young and have no fat deposits. There are many forms of collagen deficiencies that cause your issue, some of them are under the name Ehlers-Danlos Syndrome and it would be important to find out if you have any genetic explanation. This would help you know how effective collagen building treatments will be in your instance.
The next step after Morpheus x 3 sessions would be Renuvion to your neck. This is a 30 minute office procedure with minimal recovery.
