What type of light is often used for anti-aging treatments in esthetics?

In esthetics, red light is commonly used for anti-aging treatments due to its ability to penetrate the skin at a deeper level. This type of light therapy, often referred to as low-level laser therapy (LLLT) or photobiomodulation, stimulates collagen production, enhances circulation, and promotes cellular regeneration. The increased collagen helps to improve skin elasticity and reduce the appearance of fine lines and wrinkles, which are key indicators of aging.

While other colors of light have their benefits for various skin conditions—such as blue light for acne due to its antibacterial properties and green light for pigmentation issues—the specific capabilities of red light in promoting overall skin rejuvenation and anti-aging effects make it the preferred choice in this context.
