Mechanisms of Different Types of Facial Masks
1. LED Light Therapy Masks
Red light (630–660 nm) helps improve skin microcirculation and stimulates collagen synthesis, while blue light (415 nm) assists in inhibiting Cutibacterium acnes, the bacteria associated with acne. Studies indicate that continuous use for 4–8 weeks (3–5 sessions per week) may lead to visible improvements in skin brightness or reduction of inflammation. However, due to lower energy output compared with professional in-clinic devices, the overall effects tend to be milder.
2. Radiofrequency (RF) / Microcurrent Masks
These masks work by using electrical currents to stimulate muscle contraction or by generating heat within the dermal layer. They may temporarily improve facial firmness and contour. The perceived “instant lifting effect” after a single session is often caused by mild edema (swelling), while long-term efficacy lacks strong clinical evidence, and the depth of action remains limited.
3. Other Functional Masks
Examples include penetration-enhancing masks used in combination with serums or essences. These primarily create an occlusive environment to enhance ingredient absorption. The actual results largely depend on the active ingredients in the skincare products used, as the mask itself does not deliver an active therapeutic effect.
