Does LED Phototherapy work? | Melasma Dr Davin Lim

LED light phototherapy is a gentle form of low laser therapy. Dermatologists prescribe blue, red & yellow wavelengths to gently & effectively treat conditions such as acne, rosacea, as well as promote collagen production. This can speed up wound healing & aid in skin rejuvenation. This treatment works at a cellular level to stimulate the healing mechanisms in the skin. Red light stimulates collagen production, speeds up wound healing & reduces inflammation. This wavelength is frequently used post laser resurfacing or following skin surgery. Blue light can treat acne, however it should be used in caution on darker skin types as it can lead to post exposure pigmentation . What is iron oxide & why is it good? Iron oxide attenuates blue & high energy visible light, this wavelength can make melasma worse (that is why you should avoid LED masks).
