Based on my research, the claim that “using sunscreen daily is harmful to your skin” is false. Here’s what I found:
First of all, a Q&A site like Quora.com is not a valid source as the information comes from individual users instead of licensed professionals. After a quick google search of the main claim “Is using sunscreen daily harmful to your skin?” I found multiple sources that prove that daily sunscreen is in fact crucial to protecting your skin from the harmful rays of the sun.
The first reliable source I found was an article from the American Medical Association called “What doctors wish patients knew about wearing sunscreen”. The AMA is a licensed organization with educated professionals in varying medical fields, with this article focused on statements from two dermatologists.
- Evelyn Jones, MD, a dermatologist and owner of WellSprings Dermatology and WellSprings SkinCare in Paducah, Kentucky.
- Klint Peebles, MD, a dermatologist in Washington and suburban Maryland at Mid-Atlantic Permanente Medical Group, a member of the AMA Health System Program.
The article lists multiple points on how to properly choose, apply, and reapply sunscreen. The first sentence of the article, “wearing sunscreen is one of the easiest ways to protect your skin’s appearance and health at any age,” already disproves the initial claim, with the article then going into more detail about how wearing sunscreen helps to prevent skin cancer.
Although this article is from 2022, meaning that it isn’t the most recently posted evidence, it is still a reliable source. If this claim was about politics or current events, an article from three years ago might not be the best evidence to use, but facts proven by medical professionals and dermatologists are still reliable after three years.
In addition, I investigated “The science of sunscreen” published by Harvard Health, yet another incredibly reliable source backed up by professionals of a prestigious university and medical school. Dr. Jennifer Lin, an assistant professor of dermatology at Harvard Medical School and co-director of the Melanoma Risk and Prevention Clinic at Brigham and Women's Hospital answers commonly asked questions about sunscreen. This article states the many benefits of wearing daily sunscreen, but it also addresses some potential worries that people have about sunscreen.
There is a question asking “Is there evidence that sunscreen actually causes skin cancer?” in which Dr. Lin replies with a no, stating that those who use more sunscreen are also the ones who are exposing themselves to more of the suns harmful rays. This means that there is a direct correlation from sun exposure to skin cancer, not sunscreen to skin cancer.
