I’ve had two sessions of Broadband Light Treatment. The first time I used the product recommended by the esthetician, and the second time I used this set of concentrates. The difference in healing was amazing! I healed so much faster the second time using the Y Theorem Concentrate. My skin not only looks healthier after using this product, but it IS healthier! I can see where this product would be great anytime, but it is perfect for applying after a procedure. Like a magic potion! Definitely recommend. The scent is very potent, but I stopped noticing it as much after the first use.
