Using Red Light Therapy: Before or After Skincare?: Discover the best timing for maximum benefits in your skincare routine

Red light therapy (RLT) has become a trending addition to many skincare routines, praised for its ability to improve skin tone, reduce fine lines, and promote overall skin rejuvenation. But one common question remains: should you use red light therapy before or after applying your skincare products?

According to most dermatology experts, the optimal sequence is to use red light therapy on clean, dry skin—before applying serums, moisturizers, or other topical products. The rationale is straightforward: free from skincare products, your skin better absorbs the beneficial wavelengths of red light, ensuring maximum cellular energy production and collagen stimulation. Applying creams or oils first can potentially create a barrier, slightly diminishing light penetration and the effectiveness of the therapy.

Once your session is complete, you can proceed with your regular skincare regimen. At this stage, your skin may even be more receptive to the active ingredients in your serums or moisturizers thanks to increased blood flow and cell turnover triggered by the therapy. If you’re using prescription or strong active ingredients (like retinoids or exfoliating acids), consider applying them a little later to prevent any possible sensitivity unless otherwise directed by your dermatologist.

As a designer, I view skincare routines like planning a living space—proper sequencing leads to harmonious results. Just as foundation work is done before wall treatments and décor, RLT comes first to establish the ideal “canvas.” And if you’re looking to upgrade your vanity area, integrating modern lighting or even exploring how smart home design can complement wellness routines adds both function and beauty. Innovative solutions like home designer tools can help you visualize the perfect space for both your skincare and light therapy practices, seamlessly blending wellness and style at home.

Tips 1:

For best results, clean your face thoroughly before using your red light therapy device. Avoid using products that contain reflective particles or heavy oils prior to your session, as these can block or scatter light and reduce treatment effectiveness.
