CASE REPORT
A Single Session of Combined 1064 nm Nd:YAG and 660 nm Ruby Laser–Like Therapy for Long-Standing Facial Solar Lentigines: A Case Study
Tee Pui Sin
ABSTRACT: Solar lentigines are benign hyperpigmented lesions caused by chronic ultraviolet exposure and are a common aesthetic concern, particularly on facial skin. Q-switched lasers are among the principal treatment modality due to their ability to selectively target melanin with minimal downtime and a favorable safety profile. This case reports a 53-year-old Fitzpatrick skin type IV woman who presented with bilateral cheek pigmentation of 30 years’ duration and was diagnosed with solar lentigines and concurrent melasma. She underwent a single session of combined 1064 nm Q-switched Nd:YAG (QSNY) laser and 660 nm ruby laser-like modality. Significant improvement was observed at 1-month follow-up without adverse effects. A Global Aesthetic Improvement Scale (GAIS) score of 5 (“very much improved”) was recorded. This case highlights the potential effectiveness of a combined wavelength approach in the treatment of solar lentigines, offering an effective and safe treatment option.
