"They can improve photoaging with red light. Blue light/red light can be used to treat acne, and red light can also be used to treat individuals with hair loss. LED lights certainly have a place in the dermatology and cosmetic surgery armamentarium." - Dr. Neil Sadick
"LED lights are very beneficial for skin concerns mainly including inflammation in the skin like acne and rosacea. Depending on what light you use you can target specific issues: Red is great for reducing inflammation (rosacea and blemishes), yellow energizes the skins outer later, and green treats pigmentation. Another plus is there is zero downtime with LED light therapy." - Dr. John Diaz.
