Using sunscreen is one of the healthiest things you can do for your skin. According to the US Food and Drug Administration (FDA). UU. , Good sunscreen with strong protection against UV and UV rays can prevent it from burning and reduce the development of wrinkles and other signs of aging and can reduce the risk of skin cancer. The latter part is important because more than 5 million new cases of non-melanoma skin cancer (basal cell carcinoma and squamous cell carcinoma) are diagnosed each year, according to the Foundation for Skin Cancer.
The American Academy of Dermatology (AAD) recommends choosing a broad-spectrum, water-resistant sunscreen with an SPF of 30 or more. Sandy Skotnicki, MD, a dermatologist in Toronto and author of Beyond Soap, recommends choosing a mineral sunscreen that contains zinc and titanium for daily use. Mineral sunscreens, also known as physical sunscreens, protect the skin from sunlight and tend to be less irritating and more hydrating than chemical sunscreens, which act by absorbing the rays and converting them into heat in the body. According to Piemont Healthcare.
Your work is not finished when you choose the perfect bottle. Too many people manage to spoil the application process, not makeup too much, skip vulnerable areas, etc. The most serious result of giving up sunscreen is the development of skin cancer, but this is not the only reason to apply it. According to the Cleveland Clinic, sunburn damages skin cells and blood vessels and can make the skin look older, more wrinkled, dry, discolored and coriaceous.
Dr. Skotnicki recognizes that the effect of aging sunlight is an essential reason for diligence when applying sunscreen. “Several important studies have shown that regular use of sunscreen can reduce photo-aging over time: redness, brown spots, and wrinkles,” he says. Take a study published in 2013 in the journal Clinical Dermatology, Aesthetics and Cosmetics, for example. The researchers found that exposure to UV rays was responsible for approximately 80% of the visible signs of aging on the face.
Dermatologists here share the biggest sunscreen slips we tend to do and how to frustrate them.
1. Are you Wait Until You Are at the Beach to Apply Sunscreen on your Body
If you get stuck in the sand of your ankle when you apply sunscreen, you ask to go home like a lobster. Apply sunscreen at least 20 minutes before going out, as the skin absorbs the protective ingredients, according to Dr. Leslie Baumann, a dermatologist in Miami. Put it as evenly as possible before getting dressed to avoid losing points.
3. You Skip Important Areas
It is important to apply sunscreen in all areas exposed to the sun, although some places tend to be neglected. A study published in April 2019 in the journal PLoS One revealed that nearly 20% of participants did not apply sunscreen on their eyelids and those study participants had no idea that these points had been lost. This is disturbing because the skin of the eyelid has the highest incidence of skin cancer per unit area.
The lips are another area often neglected and susceptible to damage because they contain little melanin, the protective pigment responsible for the coloring of the skin, hair, and eyes. The Skin Cancer Foundation recommends using a balm or lipstick with an SPF of 15 or higher. The use of lip gloss without any cover is a big ban, says Doris Day, MD, an associate professor of dermatology at Langone Medical Center at New York University in New York. “The moister your lips are, the easier it is for UV rays to penetrate deeper into unprotected skin,” she says. According to the Skin Cancer Foundation, bright, wet lips attract harmful UV rays. It’s like using baby oil on the skin.
4. You Don’t Bother to Reapply Your Sunscreen
The AAD found that only 33% of Americans were applying their sunscreen again at the recommended frequency, leaving the skin unprotected. “It’s not a magic potion that protects you forever,” says Andrew Kaufman, medical director of the Dermatology Care Center in Thousand Oaks, California, an associate professor of clinical medicine at UCLA School of Medicine in Los Angeles. The golden rule: reapply sunscreen every two hours, more often if you sweat a lot or swim.
According to FDA guidelines, even “water-resistant” sunscreens only need to maintain their SPF for up to 80 minutes. (According to the FDA, the label on water-resistant sunscreens will indicate whether it will remain effective for 40 minutes or 80 minutes in water). Reapplying will also help you achieve a more even distribution, says Skotnicki.

5. You Don’t Apply on Your Sunscreen Fastly Enough
If you do not apply the sunscreen evenly, you will not enjoy the promised protection on the label. Pay particular attention to the request and go through the exposed areas several times to maximize coverage. Aerosol sunscreens that do not require friction can help alleviate this problem, be careful when applying. The ADA says aerosols are convenient, but it can be difficult to know if you have covered all exposed areas. Continue spraying until a glow appears throughout the body, suggests the Foundation for Skin Cancer.
6. You Forgo Putting on Sunscreen When It’s Cloudy
Even when the sun is invisible, 80% of its UV rays still hit your skin, according to the AAD. And only 20% of Americans apply sunscreen in cloudy weather, according to the AAD. Windows block UVB rays, but most of them let UVA rays through. It is therefore important to disable them every time you leave, regardless of cloud cover.
“People have a bad idea of how much sun they are getting in. They do not realize that you do not need to lie on the beach to tan,” says Dr. Kaufman, advising you to place your sunscreen right next to your toothpaste to remind you to apply it every day.
7. You Ignore the Expiration Date
Have you used the same bottle of sunscreen year after year? You can put your skin in danger. The FDA requires that sunscreen lasts for three years. After that, it may be that the amount of protection indicated on the bottle is no longer guaranteed. Check the expiration date before applying, and if you do not see it, assume it expires three years from the date of purchase. The ADA recommends that you note the date of purchase on the bottle to help you follow it.
