“…While the side effects of cold ablation by Er:YAG laser are weaker and less common [8, 26–30], C0 2 laser is associated with a higher risk of severe adverse effects and prolonged downtime [1]. The combination of both ablation systems has not yet led to a breakthrough [31].…”

SummaryModern treatment of chronically photodamaged skin provides new, minimally invasive methods for laser intervention, using fractional, non-ablative thermal energy for an induction of dermal remodeling. The clinical efficacy coupled with a minimum "down time" for the patient has directed the development of fractional ablative laser systems. Recently introduced systems are based on CO 2 and heated Er:YAG laser systems. The clinical efficacy has been tested on one prototype each and verified their effects at a microscopic level. Initial reports suggest the results are comparable to those achieved with fractional ablative systems. We review the current possibilities incorporating our personal experience. Systematic investigations of clinical outcomes with various system settings are still needed. The possible combination of ablative and non-ablative fractional technology may also lead to increased efficacy and safety of the procedure.

“…The most effective Er:YAG lasers for the treatment of rhytides use longer pulse durations to increase the residual thermal damage depth [10]. To enhance wound healing without sacrificing efficacy, a combined approach has become popular for ASR [11].…”

Background and Objectives: We introduce and clinically examine a new concept of skin treatment called fractional photothermolysis (FP), achieved by applying an array of microscopic treatment zones (MTZ) of thermal injury to the skin. Study Design/Materials and Methods: Two prototype devices emitting at 1.5 mm wavelength provided a pattern of micro-exposures with variable MTZ density. Effects of different MTZ densities were tested on the forearms of 15 subjects. Clinical effects and histology were assessed up to 3 months after exposure. Treatment of photoaged skin on the periorbital area in an additional 30 subjects receiving four treatments over a period of 2-3 weeks was also tested. Tissue shrinkage and clinical effects were assessed up to 3 months after treatment. Results: Pattern densities with spacing of 250 mm or more were well tolerated. Typical MTZ had a diameter of 100 mm and penetrated 300 mm into the skin. Reepithelialization was complete within 1 day. Clinical effects were assessed over a 3-month period. Histology at 3 months revealed enhanced undulating rete ridges and increased mucin deposition within the superficial dermis. Periorbital treatments were well tolerated with minimal erythema and edema. Linear shrinkage of 2.1% was measured 3 months after the last treatment. The wrinkle score improved 18% (P < 0.001) 3 months after the last treatment. Conclusions: FP is a new concept for skin restoration treatment. Safety and efficacy were demonstrated with a prototype device. Further clinical studies are necessary to refine the optimum parameters and to explore further dermatological applications.

“…As a result, the pulse duration of the Er:YAG must be increased to achieve the necessary depth of thermal damage [17]. Combining the CO 2 and Er:YAG lasers may be a treatment alternative to the CO 2 laser alone [18].…”

Fractional photothermolysis: Current and future applications

Ablative lasers (CO2 and Er:YAG) provide the greatest improvement in photoaging, but significant adverse effects limit their use. Nonablative lasers have reduced adverse effects, but limited efficacy. Fractional photothermolysis (FP) produces arrays of microscopic thermal wounds called microscopic treatment zones (MTZs) at specific depths in the skin without injuring surrounding tissue. Wounding is not apparent because the stratum corneum remains intact during treatment and acts as a natural bandage. Downtime is minimal and erythema is mild, permitting patients to apply cosmetics immediately after treatment. As with other nonablative laser modalities, multiple treatments are required. FP represents an alternative for treatment of dermatologic conditions without the adverse effects of ablative laser devices and can be used on all parts of the body. FP can be used for the treatment of facial rhytides, acne scars, surgical scars, melasma, and photodamaged skin.
