    TLDR LED therapy is a promising, non-invasive skin treatment, but needs standardization and personalization.
    LED therapy is a promising, non-invasive treatment in cosmetic dermatology, using specific wavelengths to target skin conditions. Blue light effectively treats acne and promotes hair growth, with a study of 417 participants showing significant hair density improvements. Yellow light reduces melasma and photoaging, while red light aids in scar healing, hair growth, and skin rejuvenation. Near-infrared light helps manage pigmentary disorders and wound healing. Combining wavelengths enhances outcomes, and ongoing research aims to personalize treatments. Despite its potential, variations in treatment parameters highlight the need for standardization and personalized approaches, with long-term studies needed to ensure safety and efficacy.
