1470 nm Laser for Facial Acne Scar Treatment
The study explores the clinical application of a 1470 nm laser combined with a fractional (Frax) handpiece for non-invasive facial rejuvenation. A total of 30 female patients with moderate facial wrinkles and skin laxity underwent treatment sessions spaced 4–6 weeks apart. The Frax handpiece utilizes a microneedle-like array to deliver subdermal laser energy in a fractional pattern, targeting collagen-rich dermal tissue while sparing the epidermis. Evaluations showed statistically significant improvements in skin tightening and wrinkle reduction, with minimal adverse effects such as transient erythema and edema. Pain scores were low, and most patients reported high satisfaction with the aesthetic outcomes. Histological analysis confirmed new collagen and elastin formation post-treatment. The findings suggest that the 1470 nm Frax system is a safe, effective, and patient-friendly modality for facial skin rejuvenation, offering advantages such as minimal downtime, precision targeting, and suitability for diverse skin types.
