Light therapy has become a popular and effective skincare treatment, offering non-invasive solutions for everything from acne to aging. Among the most widely used wavelengths are red light (around 630–660nm) そして blue light (around 415–470nm)—each offering unique skin benefits. But can these two powerful therapies be used together? The answer is yes—and combining them can be even more effective for certain skin concerns.
