What color LED light should be used for clients experiencing skin laxity?

Blue
Green
Red
Yellow

The correct answer is: Red

Red LED light is known for its ability to penetrate deeper into the skin, stimulating collagen production and promoting the repair of skin laxity. This type of light therapy enhances circulation, increases blood flow, and accelerates the healing process at a cellular level. The enhancements in collagen and elastin production can lead to a firmer, more youthful appearance, making it particularly effective for clients seeking improvement in skin tone and texture associated with laxity. In contrast, blue light primarily targets acne and helps reduce inflammation, while green light is utilized for pigmentation and redness issues in the skin. Yellow light can contribute to skin rejuvenation and promote a healthier appearance but does not specifically address the firmness and elasticity that red light excels in improving. Thus, red light is the preferred option for clients dealing with skin laxity due to its unique properties in stimulating collagen and skin repair.
