LED treatment
Light Emitting Diode treatment is also found effective for treating acne. Blue and Red lights of different wavelengths are used for this procedure. At first the dermatologist will apply a cream, which will make your skin more sensitive to light, and then expose your skin to LED lights. Both red and blue lights perform different functions. Blue light has the shortest wavelength that’s why it is able to penetrate deep into the skin and affect the oily glands so they produce less oil. On the other hand, red light has the greatest wavelength which affects the upper layer of the skin, epidermis, helping in collagen production.
