If a client is experiencing skin laxity, what color of LED light should be used?

The correct answer is red light. Red LED light therapy is specifically designed to penetrate deeper into the skin, promoting collagen production and increasing blood circulation. This process helps to enhance skin elasticity, effectively addressing issues of skin laxity.

When using red light, it stimulates fibroblasts, the cells responsible for producing collagen, which is essential for maintaining the skin's firmness and structural integrity. Additionally, red light can help repair damaged skin, reducing the appearance of fine lines and wrinkles, further improving skin laxity.

The other options serve different purposes; for instance, blue light is commonly used for acne treatment, green light is beneficial for pigmentation issues and skin tone evening, while yellow light focuses on improving skin resilience and reducing inflammation. However, for the specific concern of skin laxity, red light therapy is the most effective choice.
