Skin cancer is described as the most common cancer worldwide, and the awareness-month messaging is consistently blunt about it being largely preventable β which puts a lot of weight on the basics actually being followed, not just known.
What the fact-checking actually comes down to
- Sunscreen every day, including cloudy and winter days β the "only when it's sunny" instinct is one of the most common gaps.
- A real UPF number beats a vague "sun protective" label β the same standard we apply to every item in our own catalog.
- Coverage area matters as much as the rating β a high-UPF short sleeve still leaves forearms exposed.
Why this matters twice over for photosensitive skin
General skin-cancer prevention and lupus-related sun protection point toward the same habits β real UPF ratings, consistent coverage, broad-spectrum sunscreen β even though the underlying risk (cancer versus a symptom flare) is different. You don't need two separate routines; one good one covers both.
