Skin Tightening 

             Radiofrequency microneedling



Dr. Dannaker knows the so called 'skin tightening' market is confusing.  He has used many of these tightening modalities and rejected most.  Some work well but only on a small percentage of patients.  Some highly touted devices don't always impress.  Dr. D  has used thread lifting and thus far, is not highly impresed with the long-term results.  Volumizing with Sculptra and/or fillers or fat is often part of the skin tightening solution for many patients.  The doctor might even suggest a referral for a facelift in some cases, and will present to you his 'bottom line' for what you might expect with non-surgical treatment results.  Patients need to know how much, how many and how often and Dr. Dannaker is all about giving you this information blended by his decades of first hand experience.  CO2  laser resurfacing and tightening is sometimes the best option but has some risks and downtime.  For those under 40-50, combining non-ablative laser resurfacing with radiofrequency microneedling may be a solution. Typically, combining lasers with artistic volume restoration can be helpful. (Sculptra, fat and/or fillers).  Reaching your goals is important along with being aware of the limits of the current technology. Dr. Dannaker is an early adopter of laser and energy based technology, his experience dates back to the 1990's!   Our center  has many devices, and the technology Dr. Dannaker feels will enable him to give you, the patient, results.

Fractional RadioFrequency (RF microneedling)

FraxRF or Fractional Radiofrequency tightening utilizes a  minimally invasive fractional Radio Frequency device with micro-needle electrodes. It provides direct heat with both epidermis and dermis through precise depth control which is adjustable.  Recent RF delivery systems include fractional RF which is a particularly intricate variation in which bipolar RF flows amid an array of micro electrodes ceasing thermal zones of tissue heating at precise and targeted depths.  Fractional RF improves skin smoothness, wrinkling, and acne scarring, with a tightening benefit up to 37% of a face-lift.

Dr. Dannaker has pioneered intial studies into this new and emerging field and has published in the prestigious journal, Nature (below0:

  • Abstract:  Radiofrequency (RF) energy can be emitted into the skin, either non- or invasively, via a monopolar mode that utilizes an active electrode and a grounded electrode or via a bipolar mode that employs two active electrodes. In this experimental study of RF tissue reactions, bipolar RF energy was emitted in vivo to micropig skin at varying microneedle penetration depths, signal amplitudes, and conduction times. Immediately after RF treatment, skin samples exhibited RF-induced coagulation columns of thermal injury, separately generated around each microneedle in the dermis. In ex vivo bovine liver tissue, the thermal coagulation columns were found to be concentrated maximally around the pointed tips of each electrode. After a RF conduction time of 2 seconds, the individual areas of thermal coagulation began to converge with neighboring RF-induced coagulation columns; the convergence of coagulation columns was found to start from the tips of neighboring electrodes.

Fractional RadioFrequency microneedling is clinically proven. The histology images below show the discrete coagulative injury zones in the dermis while sparing the epidermis. The natural healing process, following the skin rejuvenation treatment, replaces the damaged zones with new collagen and elastin.

      Dr. Dannaker Performing a Fractional RF


    •  Improves skin tone and helps fade hype pigmentation (93%)
    •  Reducing pores in the face (87%),
    • Appearance of fine lines and wrinkles (77%),
    • Improvement in skin tightening of the face (70%),
    • Reduction of nasolabial folds (57%).

 "Non-surgical facelift"

  • FraxRF  is used to rejuvenate the skin, improving its elasticity, and in the treatment of acne scarring by the use of the reserve power of the healthy tissue surrounding the treatment zone.
  • The treatment does not affect daily life. After the treatment, erythema and swelling lasts from 1 to 3 hours.
  • With sophisticated technology, strong energy is delivered directly to the target area. It covers the entire face: the centre of the forehead, flabby cheeks, areas around the eyes and jaw line.

Indications for Frax-RF system:

  • Advanced aging and photoaging of the skin
  • Wrinkles and skin laxity of the face
  • Facial and acne scars
  • Stretch Marks
  • Pigmentation
  • Body tightening ie. legs, arms

Effects visible immediately after the treatment of Frax- RF:

  • Significant improvement in skin laxity 
  • Improves skin elasticity
  • Improvement in skin tone
  • Wrinkle reduction
  • Reduction of discoloration
  • Decreased activity of the sebaceous glands

Varia Yag Laser for Facial Rejuvenation and Tightening

"Tightening of the skin other than the face is challenging, especially when the patient desires little to no downtime. Yag laser (Varia) and radiofrequency (Aluma, Thermage) offer some improvement but the results can be variable. Combining various lasers and other modalities appears to improve the skin's response. I always attempt to give the patient an accurate range of expected results before embarking on a treatment plan." 

Dr. Dannaker

There is no downtime after treatment, you can have a treatment and resume regular activities immediately after the procedure.


Patients experience a more comfortable laser procedure with CoolTouch's Exclusive Patented Thermal Quenching™ Post-Cooling
A pulse of laser light, penetrates deeply into the dermis to the target. Selective absorption occurs. After absorption heats the dermis, a pulse of cooling selectively protects surface structures and quenches the heat rising from the dermis.
