Halo is a laser skin rejuvenation treatment that improves your skin with minimal downtime. One of the greatest things about Halo treatment is the dual-wavelength process (both ablative and non-ablative) that incorporates a cooling system to ensure comfort throughout the treatment. One wavelength helps reduce pigmentation and discoloration of the skin by targeting the outer layer (epidermis). The other wavelength penetrates the skin even deeper to reverse the damage below the skin.
