Lower Face & Jowls
Softens the jawline and lifts mild jowling without surgery

Non-invasive radiofrequency therapy that firms loose skin and stimulates collagen without surgery or downtime
Big Pine Key, FL
Most patients first notice it at the end of the day — cheeks sit lower, the jawline softens, the underarm or abdomen has a looser quality creams and exercise no longer reach. This is collagen and elastin loss, accelerated by sun exposure, hormonal shifts, weight changes, and time. Surgery isn't always the right answer, especially for patients who can't take multi-week recovery or only need a moderate, natural-looking improvement.
Denza is an advanced energy-based platform that delivers controlled heat into the deeper layers of the skin to contract existing collagen and stimulate new fibers. Over a series of treatments, this gradual remodeling firms and lifts without a scalpel or downtime. Because the energy targets the dermis rather than breaking the surface, you can get treated Wednesday and be back at work or paddleboarding Thursday.
Energy-Based Skin Tightening
Denza is an advanced non-invasive skin-tightening platform that uses controlled energy delivery to heat the dermis and subdermal connective tissue to a therapeutic temperature. At that temperature, existing collagen contracts immediately (the firming you feel right after a session), and a wound-healing cascade is triggered that produces new collagen and elastin over the following weeks and months.
The protocol typically involves a series of 4-6 sessions spaced 1-2 weeks apart, followed by a peak-results window at 3-6 months as new collagen continues to remodel. There is no incision, no anesthesia, and no real recovery, just mild warmth and pinkness that resolves the same day. The platform can be used on the face (lower face, jowls, neck), as well as the abdomen, arms, knees, and other body areas where laxity is the chief concern.
Because Florida Keys Primary Care & Wellness is a physician-led practice, Dr. Keifer reviews your medical history before treatment and combines Denza when appropriate with treatments such as Emface facial rejuvenation, dermal fillers, or ADVATx laser resurfacing.

Realistic expectations matter
Denza works best in patients with mild-to-moderate skin laxity who want a real result without surgery or downtime. During your free consultation, Dr. Keifer or Tommy will assess your skin quality, the degree of laxity, your overall health, and your goals to confirm whether Denza is the most efficient choice or whether a combination plan is better.
Because every plan is reviewed by Dr. Keifer with access to your full medical chart, contraindications are caught before treatment.
What to expect during your Denza session, from skin assessment to comfortable in-office treatment
Dr. Keifer or Tommy Iglesias evaluates your laxity, sets goals, and confirms candidacy.
Tommy cleanses the area and applies a thin layer of conductive gel for even energy delivery.
The Denza handpiece is moved across the area in a calm, methodical pattern; you feel a deep warm massage.
Soothing post-treatment cooling and a moisturizer are applied before you leave the renovated treatment room.
We schedule your next session 1-2 weeks out and reassess at the 3-month and 6-month mark.

Most patients do a series of 4-6 sessions spaced 1-2 weeks apart, followed by 1-2 maintenance sessions per year to extend results.
Lower face, jowls, neck, submental, abdomen, arms, knees, and décolletage are the most common areas. We also treat smaller specific concerns based on consultation.
No. Most patients have brief warmth and mild pinkness that resolves the same day, then return to all normal activities including work, exercise, and outdoor life.
Initial firming is felt right after the first session, becomes visible at 2-4 weeks, and peaks at 3-6 months as new collagen continues to remodel.
Most patients describe Denza as a deep, warm massage. Settings are adjusted to keep you comfortable throughout. No anesthesia is needed.
