You apply sunscreen to your face, your neck, maybe even the tops of your ears. But when was the last time you protected your lips?
For many people living in South Florida, the lips are one of the most overlooked and most vulnerable spots on the body when it comes to sun damage. If you spend time outdoors, whether at the beach, on the water, at the park, or just commuting, your lips are absorbing UV radiation every single day.
As spring temperatures climb and outdoor time increases across Broward County and Miami-Dade County, this is exactly the right time to understand what that exposure can lead to, and what to watch for.
The skin on your lips is thinner than almost anywhere else on your body. It contains very little melanin, the pigment that provides some natural protection against ultraviolet radiation. That combination makes lips particularly susceptible to cumulative sun damage over time.
As we've discussed in our post on why South Florida's sun makes year-round skin cancer screenings essential, UV exposure in this region does not let up. Your lips are absorbing that radiation every month of the year.
Actinic cheilitis is a precancerous condition that develops on the lips as a result of long-term sun exposure. Think of it as the lip equivalent of actinic keratosis, the rough, scaly patches that can appear on sun-damaged facial skin.
It most commonly affects the lower lip and can develop gradually over years. Many people mistake it for dry, chapped lips and never think to have it evaluated by a dermatologist.
Signs of actinic cheilitis may include:
If left untreated, actinic cheilitis can progress to squamous cell carcinoma, a form of skin cancer that can spread if not caught early. This is why early evaluation matters.
Squamous cell carcinoma is the most common form of skin cancer to develop on the lips. It can start as actinic cheilitis, or it may appear as a new lesion on its own. Because the lips are not always carefully examined during routine check-ins, lip skin cancer is sometimes diagnosed later than skin cancers in more visible locations.
Warning signs that warrant a prompt visit to a dermatologist include:
It is worth emphasizing that many of these changes are benign or easily treatable when caught early. Noticing something unusual and getting it looked at promptly is always the right move. There is no such thing as an unnecessary skin check.

The good news is that protecting your lips from UV damage is simple, even if it is a habit most people have never developed. Building lip sun protection into your daily routine can meaningfully reduce your long-term risk.
