What is the primary function of green LED light in skin treatments?

Reduces signs of aging
Helps with hyper-pigmentation and detoxifies skin
Reduces acne
Promotes deeper penetration of skin products

The correct answer is: Helps with hyper-pigmentation and detoxifies skin

Green LED light has been found to stimulate the production of melanin in the skin, which can help with hyper-pigmentation. It can also help to detoxify the skin, improving overall complexion. The other options, while beneficial for skin treatments, are not the primary function of green LED light. Red LED light is known for reducing signs of aging and promoting collagen production. Blue LED light is typically used to reduce acne. And while green LED light can help with deeper penetration of skin products, this is not its primary function in skin treatments.
