Should I Use Sunscreen?

Baby with Sunscreen 2I’m confused about whether sunscreen is necessary to protect my skin, or if it might actually be bad for my health. 

Sunscreen use is a complicated issue, so before we dive into recommendations, here are a few facts to keep in mind:

You Need Some Sun Exposure to Get Enough Vitamin D. Your body produces this essential vitamin whenever your bare skin is exposed to the sun’s ultraviolet rays. Unfortunately, as many as 32 percent of Americans have inadequate levels of vitamin D, which increases the risk of cancer, diabetes and cardiovascular disease. Some researchers suggest that 5 to 30 minutes of direct sunlight at midday, twice a week, will give you enough vitamin D. However, many factors, including age, skin tone and latitude affect vitamin D production.

Sunscreen Alone Won’t Prevent Cancer. Sunscreen may protect your skin to some extent; however, the pain and blistering of sunburn serves as a warning that you are getting too much solar radiation. Thus, sunscreen may lull some people into complacency and overexposure to the sun. Some studies have found that frequent sunscreen use is actually associated with a higher incidence of malignant melanoma, the deadliest form of skin cancer.

You Can’t Rely on the SPF Number. Sunscreen generally doesn’t perform as advertised, because most people don’t follow the application recommendations. Many of us don’t slather on enough sunscreen or reapply it often enough to reach advertised protection levels.



Some Sunscreen Ingredients May Be Harmful. Several common chemical UV-filters in sunscreens are hormone disrupters.

Wow, you left out an awful lot of information. People should be aware that standard sunscreens provide chemical barriers that actually block our ability to produce vitamin D. Alternatives are old-style sunscreens like zinc oxide and titanium dioxide, which provide physical barriers against sunburn without the harmful chemical additives. Standard sunscreens have around a dozen harmful chemicals in them, including several hormone disruptors and several others that actual form carcinogenic byproducts in the presence of UV light!

I enjoy visiting the beaches on the southeast coast, but during each visit, areas of my skin exposed to the Sun develop red pen-point sized spots. My dermatologist says not to worry about it and told me what it was, but I can remember. Does anyone know about this condition? During my last visit I work long pants and long-sleeved shirts and it was much better. I sometimes wonder if it is the lotion I put on for sun protection?
