Summer may bring sunshine and beach days, but it also presents unique challenges for your skin. From increased sun exposure and dehydration, your skin needs extra attention during the warmer months. In this Q&A, we spoke with Dr. Hayes Gladstone, a board-certified dermatologist, for expert advice on protecting your skin.
How do I protect myself from the sun during summer?
A: Wearing sun-protective clothing provides the best defense against the sun. Specific sun-protective clothing lines usually provide above 50 SPF coverage and are generally very lightweight, comfortable, and elegant.
Should I have any sun exposure?
A: Yes. While the sun is the major cause of skin cancer, it is also very beneficial in synthesizing Vitamin D, which is important in our immune system. The key is being exposed to the sun in moderation, generally not between 11 a.m. and 3 p.m.
What are the best sunscreens?
A: The best sunscreens are actually sunblocks. They contain either zinc, which protects against the widest range of the sun’s UVA and UVB rays, or titanium dioxide. They come in creams or powders. Most higher-end sunblocks are micronized and have tints, meaning that they will not create the old “lifeguard look.” They are also safe for coral. While the SPF is important, reapplying the sunblock after a few hours is very important.
What type of skin care regimen should I use?
A: Aside from sunblock, I simplify skin care regimens by recommending a moisturizer, a vitamin A derivative cream such as tretinoin, and an antioxidant cream. The skin is the body’s largest organ and the only one exposed to harsh environments. A moisturizer can help keep your skin supple, temporarily hydrate, and thicken. Vitamin A topicals can help reduce skin aging, such as fine lines. Antioxidant topicals may act as scavengers to go after oxygen-free radicals that can damage the skin. Choosing a moisturizer can be trial-and-error based on how dry your skin is. It has to feel good on your skin, or you will not use it. While Tretinoin prescription can dry out your skin and make your skin sensitive (you should be wearing sunblock), it has different strengths and can be initially used a couple of times per week at night. Topical antioxidants are applied once per day, usually in the morning.
Do the foods I eat affect my skin?
A: Yes, there is increasing evidence that eating foods high in antioxidants, such as berries, will help reduce free oxygen radicals, which can damage the skin. Drinking water will help hydrate your skin and keep it more supple. Eating highly refined foods, including sugar, may increase inflammation, which, similar to its effect on other organs, can be harmful to the skin.
What can I do to prevent skin cancer further?
A: Having a Board Certified Dermatologist perform a thorough skin check annually will help reduce the risk of skin cancer or at least catch it very early. While there are AI apps that may help flag suspicious lesions, it is still best to go to an expert to examine your skin. A spot that is scabbing/bleeding and either doesn’t go away or comes and goes should be examined. Similarly, a mole that is changing should be examined. There are also adjunct treatments covered by insurance, such as photodynamic therapy, that can reduce the number of precancers, which also may reduce the risk of actual skin cancer.
I tan all the time. Am I really at risk for skin cancer?
A: Yes. Individuals who tan all the time or people of color are still at risk for skin cancer. It is important to have your skin checked since sometimes these skin cancers may go unnoticed and be diagnosed when they are more advanced.
