Can back-to-back or even simultaneous application of red and blue LED light therapy treatments cancel each other out?

Question

I'm getting conflicting information while choosing an at-home LED light therapy device for acne treatment. The makers of Clear Rayz insist that if I use their blue LED, I should avoid using their red on the same day and vice versa. That device has blue & red lights on reverse sides. But other devices, such as the Neutrogena mask, offer simultaneous blue and red light treatment. Can the simultaneous or even same-day application of blue & red LED light therapy render treatments ineffective?

The LED lights in my practice and the LED mask I have for at-home use can all be combined and will absolutely not cancel each other out. FDA CLEARED, 3-minute wrinkle reducing, acne fighting LED device for the entire face. A combination of 100 lights in red mode + 62 lights in blue mode work together to smooth wrinkles, diminish discoloration, and clear acne for a beautiful, youthful complexion. Red lights penetrate deep within skin’s dermis to stimulate collagen production. Blue lights destroy P. acnes bacteria to reduce redness, inflammation, and prevent future breakouts. Within days, see a reduction of acne. In 2 weeks, experience a clearing of mild to moderate acne and fading lines. Optimal results occur after a 10 week course of treatment.
