Yes, I found that out in the Texas sun. Looks much softer now that I have not been exposed to the sun as much.

Yes this is actually how I just found out my daughter has a spot from the tan lines. Lesson learned!

Yes especially if the skin gets sunburned. The injury can trigger new patches, and tanning makes existing vitiligo more noticeable. Controlled UV exposure can be therapeutic, but ordinary sun exposure should be limited. Most importantly, always use a broad-spectrum SPF 50.

Yes, sun exposure can absolutely make vitiligo worse. When skin is damaged by UV rays, the immune system may mistakenly attack pigment cells in that area, causing vitiligo to spread or new white patches to appear.

Yes, sun exposure can absolutely make vitiligo worse. When skin is damaged by UV rays, the immune system may mistakenly attack pigment cells in that area, causing vitiligo to spread or new white patches to appear.

One MyVitiligoTeam member shared: "I used to live in Arizona and go to the lake a lot. One day, I got a bad sunburn on my forehead. After a couple of days my sunburn began to turn white." Here are some key ways to protect your skin:

- Wear broad-spectrum sunscreen with SPF 30 or higher daily, even on cloudy days
- Check the UV index — if it's 3 or above, protect your skin regardless of the weather
- Wear UPF-rated clothing, wide-brimmed hats, and sunglasses
- Avoid direct sunlight during peak hours

A good rule of thumb: cloudy doesn't mean safe! UV rays pass right through clouds, so sunscreen should be a daily habit, not just a sunny-day one.
