solar lentigines - #20492
I am really freaking out about these brown spots I've noticed on my arms and face, and I think I might have solar lentigines. Like, I've spent a ton of time in the sun over the years, you know? I figured they were just freckles at first, but they keep multiplying and getting darker, which is super worrying. My grandma had something like this, and I remember her telling me about how they’re related to sun exposure. I went to the dermatologist last week, and he said it’s likely solar lentigines but didn’t give me much info on how to deal with them. He mentioned something about how there’s no real "cure" but that treatments like laser could help. I guess I thought maybe they could just vanish one day, right? Now I'm wondering — are there lifestyle changes that could help prevent more solar lentigines from showing up? Like, should I avoid the sun entirely or just wear more sunscreen? It’s crazy because I’ve been applying sunscreen and wearing hats but these spots are still popping up. Is it too late to do something? Do they mean anything serious for my skin health? What have other folks done when dealing with solar lentigines? Any advice would be super appreciated.

Doctors' responses
Solar lentigines, commonly known as age spots or liver spots, are indeed linked with long-term exposure to UV radiation, which accelerates the production of melanin in the skin. They’re considered mostly a cosmetic issue but can be distressing due to their appearance. Importantly, they are generally benign, meaning they don’t suggest anything seriously wrong with your skin’s health. However, staying proactive about skin health is important. You mentioned using sunscreen and wearing hats, which are excellent preventative measures. To prevent further spots, try using a broad-spectrum sunscreen with an SPF of 30 or higher consistently, even on cloudy days, to block both UVA and UVB rays. Reapply it every two hours, especially if you’re swimming or sweating. Also, it’s sensible to seek shade when the sun is at its peak between 10 a.m. and 4 p.m. Additionally, continuing to wear protective clothing like long sleeves and brimmed hats could further decrease UV exposure. Some lifestyle adjustments like adding more antioxidant-rich foods into your diet (like fruits and vegetables) may support skin health overall, though they don’t directly prevent lentigines. As for treatment, while there’s no “cure,” procedures like laser therapy, chemical peels, or cryotherapy can effectively lighten or even remove existing spots. Discuss these with your dermatologist to explore what might work best for you. Remember, the appearance of new solar lentigines might slow down with these preventive measures, but they can’t fully eliminate existing conditions or guarantee new ones won’t appear. Though they’re typically harmless, any sudden changes in existing spots—or appearance of new spots that seem unusual—should be evaluated by a dermatologist to rule out skin cancer. While there’s no urgent health risk in your case based on current details, always follow up with a healthcare provider if any spots ever appear concerning.
