Question

Red Light Therapy is good for your skin

Answer 1

It seems to be generally agreed upon within the medical community that red light therapy is effective. The author of the article is a medical doctor, and all cited sources including the FDA are reliable. Even long hours of exposure to red LED light supposedly cause mild irritation, as red light can also be useful for sensitive skin.

There is substantial evidence that red light therapy can deminish acne scars and wrinkling, by stimulating collagen production in the skin. Dermatologists say that it can be effective for some uses, but not all claimed uses.

Answer 2

While investigating the claim "Red Light Therapy is good for your skin" I found that the claim is partially true but over simplified. This conclusion was came to after looking into multiple sources from places like Cleveland Clinic, Stanford Medicine, and The National Library of Medicine. 

My primary source is Cleveland Clinic because it explains how it works and how it is thought to benefit the skin and heal scars and acne. But it also acknowledges that more studies are needed to further confirm. My secondary source is Stanford Medicine because it interprets and summarizes the scientific research. It explains what parts the research does and doesn't support. Even though these sources are credible they all acknowledge the lack of research and mostly reference the promise not the hard facts on what the benefits are.

Answer 3

Although research is limited the American Academy of Dermatology (AAD) says that moderated use is beneficial to improve various skin complications. Red light is not a direct cure to symptoms like acne, dark spots, or texture but it can sooth symptoms. Looking at your source I am a bit skeptical the author's authority, Katherine Fiala, MD is a certified dermatologist but I found it hard to find more information on her research or other articles. Looking past that, the information in the article and credible. Also the source, Baylor Scott and White Health is focused on health related topics which gives them more authority to speak on the topic.
