ThermiSmooth is a non-invasive skin-tightening and rejuvenation treatment that uses controlled radiofrequency (RF) energy to gently heat the deeper layers of the skin. It’s designed to tighten loose skin, smooth fine lines, and improve skin texture — especially on the face, neck, and other areas with mild to moderate skin laxity.

Unlike surgical facelifts or ablative lasers, ThermiSmooth does not require incisions, anesthesia, or downtime. Many patients describe the sensation as similar to a warm-stone massage. UAB Medicine+1
How It Works (Mechanism)
-
The device uses a temperature-controlled hand-piece to deliver RF energy through the skin’s surface. The RF current generates heat by resistance as it passes through tissue. Lippincott Journals+1
-
Most clients will be treated at 41-43 degrees Centigrade. When skin temperature reaches a therapeutic range (usually around 40–45 °C), heat causes immediate tightening of existing collagen fibers and triggers a biological response that stimulates new collagen and elastin production over subsequent months. The subtle improvement over months is also a bonus for those wanting a more natural approach. La Jolla Cosmetic Laser Clinic+2South Lake Dermatology Store+2
-
This remodeling process improves skin elasticity, reduces fine lines/wrinkles, and lifts mild sagging. Improvements typically develop gradually over 3 to 6 months post-treatment. Cosmetic Laser Skin Surgery+2FVPSurgery+2
What ThermiSmooth Can Do
Areas commonly treated:
-
Forehead, cheeks, under-eyes, around the mouth
-
Jawline, jowls, neck
- Lower face, perioral and periorbital (“crow’s feet” / “smile-line”) zones Forefront Dermatology+2Otolaryngology–Head & Neck Surgery+2
- Abdomen, Arms, Thighs can be treated but we typically use other types of RF technology that employs larger treatment heads or heat delivered with bipolar technology.
Benefits:
-
Tightens mildly lax skin
-
Smooths fine lines and wrinkles
-
Improves skin texture and elasticity
-
No downtime — patients may resume normal activity immediately Cosmetic Laser Skin Surgery+2Dr. Fechner+2
-
Safe for all skin types (minimal risk of pigmentation or scarring) RealSelf.com+1
Who is a Good Candidate?
-
Individuals with mild to moderate facial or neck skin laxity. This laxity can be from aging, sun damage or weight loss.
-
Patients who want a non-surgical, low-risk option with minimal discomfort and no downtime
-
People with realistic expectations — very loose skin, heavy sagging, or advanced age-related laxity may be better served by more intensive treatments (e.g., surgery) Cosmetic Laser Skin Surgery+1
What to Expect During Treatment & After
-
Sessions generally take 30–60 minutes, depending on the area treated. Jennifer Boll, MD+1
-
Treatment feels like a warm massage; no anesthesia needed, though mild warmth or discomfort may be felt. UAB Medicine+1
-
Typically 3–5 treatments spaced 2–4 weeks apart are recommended for optimal results. Dr. Fechner+1
-
Mild redness or warmth may appear immediately after, but no downtime is required. Forefront Dermatology+1
-
Gradual improvement over weeks to months — as new collagen remodels, skin becomes firmer and smoother. Cosmetic Laser Skin Surgery+1
Limitations & What It Won’t Do
-
ThermiSmooth is best for mild to moderate signs of aging. It cannot deliver the dramatic lifting a surgical facelift can when skin laxity is severe. Cosmetic Laser Skin Surgery+1
-
While many RF-based treatments are marketed aggressively, high-quality scientific evidence remains limited. A 2015 review noted that parameters and long-term outcomes vary widely and called for more rigorous trials. PMC+1
-
As with all aesthetic procedures, results vary individually. Maintenance treatments may be needed over time to sustain the effect.
Bottom Line
ThermiSmooth offers a comfortable, non-surgical way to gently tighten skin, smooth fine lines, and refresh facial or neck appearance with no downtime. For those with mild-to-moderate skin laxity who prefer a low-risk, no-anesthesia option, it represents a practical alternative to surgery or ablative lasers. However, it’s not a substitute for more aggressive lifting procedures when significant sagging or deep wrinkles are present. As with any cosmetic treatment, realistic expectations are vital.
