Anti-Ageing
A study published in the journal Photomedicine and Laser Surgery found that participants who received red light therapy experienced a significant reduction in wrinkle depth and skin roughness compared to the control group (1).
Another study published in Dermatologic Surgery showed that red light therapy improved skin complexion, increased collagen density, and reduced wrinkle appearance, confirming its benefits for anti-aging treatments (2).
ACNE
A study published in the Journal of Clinical and Aesthetic Dermatology reported significant reductions in acne lesions and inflammation in participants treated with blue light therapy (3).
Another study in the Journal of Cosmetic and Laser Therapy found that combining blue and infrared light therapy resulted in substantial improvements in acne severity and skin texture, with participants experiencing fewer acne lesions and reduced inflammation (4).
