The HALO is the first in its class of fractional lasers to provide hybrid fractional laser (HFL) technology to produce targeted, reproducible, and effective results that improve the appearance of skin conditions, such as wrinkles, dark spots, discoloration, acne scars, and laxity.

The HALO hybrid fractional laser combines ablative (destruction of tissue by vaporization) and non-ablative wavelengths delivered to the same microscopic treatment zone to achieve maximum clinical results and minimal downtime. Every skin is different with different needs, so you are given customized skin treatments to match your specific skin concerns and lifestyle.

Benefits of Halo Hybrid Fractional Laser:

  • HALO laser treatments are safe and effective
  • Halo treatment time takes only 15-30 minutes
  • Procedure uses dynamic thermal optimization to add comfort
  • Laser treatment allows fast healing, with an average of 3-4 days mild swelling
  • Results are evident as early as one week showing that Halo glow

Areas to treat with Halo laser:

  • Face, neck, chest, hands, & legs
  • Improves: 
    • Sun damage
    • Hyperpigmentation
    • Fine lines and wrinkles
    • Scarring
