What serum should I use with red light therapy to maximize its efficacy and ensure optimal skin rejuvenation? With a myriad of options available on the market, how do I discern which ingredients complement the photonic stimulation provided by red light? Are there specific serums enriched with antioxidants, peptides, or hyaluronic acid that might synergistically enhance the therapeutic benefits? Should I prioritize formulations that boast superior absorption qualities to ensure the peptides penetrate deeply into the dermis? Furthermore, do certain formulations work better for specific skin types or conditions—such as acne, aging, or hyperpigmentation? How crucial is the timing of application relative to the therapy session? If I apply a serum immediately before or after exposure to red light therapy, will that alter the outcome? What should I look for in terms of scientific backing or dermatological recommendations when selecting a serum to integrate into my skincare regimen alongside red light therapy?
