Sun exposure doesn't just cause wrinkles — it can cause skin cancers that require surgery and may permanently change your face.

Scientific Claim

Chronic ultraviolet radiation exposure is the primary etiological factor in the development of non-melanoma skin cancers, specifically basal cell carcinoma and squamous cell carcinoma, which frequently occur on sun-exposed facial regions and can result in significant structural disfigurement upon surgical excision.

Original Statement

UV-A and B. -And then more concerned with head and neck, you're more concerned about non-melanoma skin cancer. So basal cell carcinoma, squamous cell carcinoma. And you might think oh that's not a big deal, it's just skin cancer, just cut it out. But cutting out a facial skin cancer can be deforming to the face.

This study found that women who got more sun over their lives, especially early on, were more likely to get common skin cancers like BCC and SCC — exactly what the claim says. Sun exposure is the main cause.

This study found that people who work outside in the sun, like gardeners and construction workers, are much more likely to get a type of skin cancer called SCC because of too much sun exposure — which is exactly what the claim says.

Red tattoos, ultraviolet radiation and skin cancer in mice

Randomized Controlled Trial
Animal
2017 Nov

The study found that UV light alone caused skin tumors in mice, and red tattoo ink only made the tumors grow a little faster—but didn’t cause them by itself. This supports the idea that UV light is the main cause of these skin cancers.

This study says that too much sun exposure, especially UV rays, is the main reason people get a common type of skin cancer called basal cell carcinoma. That matches what the claim says, so it supports it.
