Red light therapy, known as photobiomodulation, has evolved from clinical applications in hair regrowth to becoming a popular at-home skincare treatment for various conditions.
Dr. Prem Tripathi states that RLT's initial use was as a post-operative recovery tool in plastic surgery, but its versatility has opened avenues for at-home devices.
Despite widespread popularity, Dr. Annie Liu cautions that research on the long-term effects of at-home red light therapy devices is limited compared to in-office treatments.
RLT stimulates fibroblasts to produce collagen, which enhances skin plumpness and elasticity, thereby promoting cellular repair and regeneration.
