LED (light emitting diode) refers to the specific type of bulb and the source of this visible light. “It’s been shown that the light emitted can affect the biology of the skin in a positive way, reducing inflammation and helping with conditions like acne, rosacea, and eczema. Other benefits: There are no side effects, no downtime, and this kind of treatment can easily be done in the privacy of your own bathroom (at-home LED devices are becoming more and more popular and are typically less costly; at the dermatologist, treatments costs around $500, says Frank ).

On the most extreme end of the spectrum are lasers or what’s known as ‘coherent light’, which can be used to address specific skin conditions, Dr. Frank explains. Based on the wavelength, lasers can treat everything from broken blood vessels to dark spots to irregular texture, he says. And while laser treatments can be pricey (be ready to shell out anywhere between $600 and $1250 per treatment, depending on the type of laser and where you live) the major pro is that they can target these exact issues without damaging the rest of the skin.
