Summer sunshine is here, and while pool days and outdoor adventures await, so does the need for serious sun protection. In a couple of recent segments with The Weather Channel, Board-Certified Dermatologist Dr. Pearl Rimtepathip shed light on everything you need to know to confidently choose and use sunscreen, so your skin stays healthy year-round.
Chemical vs. Mineral Sunscreens: What’s the Difference?
Navigating sunscreen labels can be confusing, but according to Dr. Pearl, the key lies in understanding the active ingredients.
- Chemical sunscreens absorb into the skin and then absorb UV rays, converting them into heat.
- Mineral sunscreens, also known as physical blockers, sit on the skin’s surface and reflect UV rays away.
To find a mineral sunscreen, Dr. Pearl recommends scanning the ingredient list for zinc oxide or titanium dioxide. Many bottles will state “mineral” on the front, but checking the ingredients is the most reliable way to ensure what you’re getting.
Are Spray Sunscreens Safe?
Spray-on sunscreens may seem convenient, but they come with concerns. “Many spray formulations are chemical-based and can be inhaled, which may irritate the lungs and nasal passages,” said Dr. Pearl. She also pointed out that sprays can be unreliable on windy days—“you might miss yourself entirely, or protect the person behind you instead!”
When possible, opt for lotions, creams, or even sticks for a more even, thorough application.
What About Sunscreen Pills or Gummies?
With the rise of wellness supplements, edible sunscreens like HelioCare have become trendy. While they contain antioxidants that may help reduce oxidative stress on the skin, Dr. Pearl emphasized that these should never be used as a standalone solution.
“They can be a helpful supplement,” she said, “but not a replacement solution.”
Reapplying is Key
One of the most common sunscreen mistakes? Not reapplying. Even if your sunscreen is labeled “waterproof” or “water-resistant,” Dr. Pearl advises reapplying every 2–3 hours, especially after swimming or sweating. This same rule applies to the little ones as well.
Don’t Forget Sun-Protective Clothing
Sunscreen is essential, but it’s not the only defense against the sun’s harmful effects. Dr. Pearl recommends:
- Avoiding peak sun hours between 11 a.m. and 3 p.m.
- Wearing wide-brim hats, sunglasses, and UV-protective clothing for added protection. And on the topic of UV-protective clothing, Dr. Pearl reminds people- “We still recommend applying sunscreen underneath protective clothing for full coverage.”
- Seeking shade whenever possible.
What SPF Number Should You Choose?
When it comes to SPF, Dr. Pearl recommends a minimum of SPF 30 for the average person.
- If you have a history of skin cancer, go for SPF 50 or higher.
- Between SPF 50 and 100, the difference in protection is minimal—only about 1%—but the price difference is higher.
Sunscreen Is a Year-Round Must for Everyone
Dr. Pearl reminded The Weather Channel viewers that sunscreen isn’t just for summer. Even if it’s raining or snowing, UV rays are still present. Snow, in particular, can reflect sunlight and cause unexpected sunburns. That’s why sunscreen is essential 365 days a year.
She is also frequently asked if people with darker skin tones still need sunscreen. “While melanin offers some protection, it’s not enough”, Dr. Pearl cautioned. Fortunately, there are now many tinted mineral sunscreens that blend well into all skin types.
Does Makeup With SPF Count?
Do you think your foundation with SPF has you covered? Not quite. “Makeup often only contains SPF 15,” said Dr. Pearl. “We recommend applying a higher-SPF sunscreen underneath for effective protection.”
From decoding sunscreen labels to rethinking your sunscreen spray habits, Dr. Pearl delivered a powerful reminder that sun protection is more than a summer ritual. It’s a lifelong commitment. With the right sunscreen (and habits), your skin can stay healthy, youthful, and safe from harmful UV damage every day of the year. Watch the videos from The Weather Channel episodes below.
