Near Infrared Technology Alma Harmony’s NIR module uses a high power light source in the near infrared spectrum to achieve safe and effective sub-dermal heating, stimulating the growth of new collagen and tightening laxity while also imparting a youthful glow to the skin. The NIR module offers separate applicators for face and body. Procedures with the NIR module may be performed via a stationary delivery method or using the In-motionTM technique for gradual heat build-up and comfortable treatment.
