Which color light is known to increase collagen and elastin production?

Red light is known to increase collagen and elastin production due to its specific wavelength, which penetrates the skin more deeply than other colors. This deep penetration stimulates fibroblasts, the cells responsible for producing collagen and elastin, leading to improved skin elasticity and overall texture. The therapeutic effects of red light have been studied extensively in both aesthetic and medical contexts, showing benefits in skin rejuvenation, wound healing, and reducing signs of aging.

In contrast, the other colors do not have the same level of effectiveness in enhancing collagen and elastin production. For example, blue light is often associated with acne treatment due to its ability to kill acne-causing bacteria, while green light can help with pigmentation issues. Yellow light is typically used for its calming effects and improving skin redness but does not specifically enhance collagen production.
