New Device for Fractional Laser Resurfacing

New Device for Fractional Laser Resurfacing

Sciton recently launched Halo hybrid fractional laser (HFL) during the 72nd Annual Meeting of the American Academy of Dermatology in March. Halo is the first and only tunable HFL, combing non-ablative and ablative wavelengths in a single pass to maximize results and reduce downtime. Halo is available on the company’s JOULE platform, which offers multiple modules to treat a wide range of indications.

Each patient is different, from their skin type, to their lifestyle, to their tolerance for downtime. HFLs offer a customized treatment with maximum results and low downtime. HFLs work by delivering ablation sequentially followed by coagulation to the microscopic thermal zone, according to a Sciton white paper.1

Halo delivers both ablative and non-ablative wavelengths to the same or different microscopic treatment zone. Halo uses 2940 nm Er:YAG to deliver 100% pure ablation between 0 µm to 100 µm into the epidermis and 1470 nm diode to deliver 100% coagulation between 100 µm to 700 µm to the epidermis and dermis. This gives Halo the ability to provide separate treatments for the epidermis, which heals quickly, and the dermis, which remodels more slowly over time. The user may choose 1 of 3 coverage-base treatment levels, and Halo calculates the exact amount of energy necessary to complete a safe and effective treatment. Additional features of Halo include Dynamic Thermal Optimization technology that ensures tunable treatments that are even from start to finish. Halo also uses intelligent energy-based parameters. Traditional non-ablative treatments with pass-based treatment protocols can be uneven, because it is difficult to see where the previous pass was placed or to know the actual number of passes performed. An energy-based system, however, ensures a consistently even treatment by measuring the size of the treatment area and calculating the energy necessary to complete the treatment. Based on clinical results, benefits of a Halo treatment include both epidermal and deeper dermal pigmentation and tone and texture in the skin.1

The Dermatologist Product Spotlight provides a summary of a white paper highlighting the technology and clinical results behind Halo.

Hybrid Fractional Laser

For the last decade, patients who did not desire deep, full-field ER:YAG resurfacing, which offered the best results but prolonged downtime, were given 2 options. Patients could choose ablative fractional treatments (fewer sessions, more downtime), or non-ablative fractional treatments (more sessions, lower downtime).1

Study Objective

A new category of fractional laser device has been developed and referred to as HFL. This study detailed the technology behind HFL and compared the technology to existing resurfacing lasers.1    


Beyond the hybrid technology, Halo offers many features that help improve usability and safety including tunable 1470 nm depth, Dynamic Thermal Optimization technology, intelligent energy-based parameters and a platform approach. Halo offers the flexibility of completely turning off ablation for users that are not qualified to use an ablative laser or for those looking for the simplest laser treatments. Both the ablative and non-ablative laser wavelengths can be delivered in the same pass, and many different permutations of depths and coverage are possible.1

Clinical Results

Halo has undergone extensive testing to perfect the HFL technology. In a study of Halo treatments on the face and neck, the investigators found that patients treated with Halo had much better appearance related to texture and pigment improvement than expected. Patients saw results in 1 to 2 treatments, while other older non-hybrid technology required 5 to 6 treatments to have similar texture changes. These additional treatments did not achieve Halo outcomes in terms of pigment correction. Also, treatment with Halo resulted in improvement in pore size and number.1


The study demonstrated that treatment with Halo can produce targeted, consistent and reproducibly effective results that improve the appearance of dermal damage with minimal to no side effects. Patients who have received even light ablative treatments prior to Halo treatments preferred the healing experience from Halo, according to the report. Reasons for the preference included no need for nerve blocks, less overall pain after treatment, the ability wear makeup 1 day after treatment and short duration of peeling.1
