Hello Marsha,
if you are looking for a concrete study about the effect of IRL as an anti-aging here is the link for a good read : A Controlled Trial to Determine the Efficacy of Red and Near-Infrared Light Treatment in Patient Satisfaction, Reduction of Fine Lines, Wrinkles, Skin Roughness, and Intradermal Collagen Density Increase
But if you are asking for personal experience, I would suggest you to browse each thread here especially those about anti-aging and skin care. A lot have given their testimonies about how IRL and RLT helped them with their acne and wrinkles.
