The pros and cons of both sunscreen products, plus the best dermatologist options.
If you only take one thing to the beach, it has to be sun protection. But when you stop by the pharmacy to stock up and start reading product labels, you notice that there are two types: sunscreen and sunscreen. What is the difference between the two, and is one better than the other? Health spoke with dermatologists to help us decode the fine print and unravel the benefits and disadvantages.
Sunscreen vs. sunblock: the basics
Containing organic chemicals such as octyl methoxycinnamate, octyl salicylate, and ecamsule, sunscreen relies on a chemical reaction to absorb ultraviolet light and convert it to heat, which is then released from the skin, says the dermatologist. Cristina Psomadakis, based in London.
On the other hand, sunscreen contains mineral ingredients like titanium dioxide or zinc oxide that physically block UV rays. So the main difference between sunscreen and sunscreen is how it protects the skin from UV rays. Sunscreen is so named because it literally blocks UV rays by forming a physical shield, while a sunscreen contains chemicals that absorb UV rays before your skin can.
Sunscreen and sunscreen also have different application methods. Because sunscreen only works when absorbed through the skin, you need to rub it on. But you can simply apply sunscreen, as it acts as a physical barrier. However, you should apply sunscreen evenly, as UV light can affect any exposed part of the skin, no matter how small. Because sunscreen doesn’t rub, it usually leaves a white tint on the skin, while sunscreen completely disappears.
In general, sunscreens are designed to protect against UVA rays, which promote skin damage. Sunscreens, however, are formulated to stop the damage from UVB rays, the kind that causes a sunburn. But many sunscreens and sunscreens check both boxes, which helps prevent wrinkles and sunburn.
Any side effects of sunscreen and sunblock?
If used correctly, the side effects of sunscreen should be minimal. It is important to choose the right product for your skin type, especially if you have sensitive skin. “As with anything applied to the skin, there is a possibility of skin irritation or reaction,” Connecticut-based dermatologist Rhonda Q. Klein, MD told Health.
“Some sunscreens contain oil and can cause acne,” New York City dermatologist Deborah Jaliman, MD told Health. “If you have very sensitive skin, others may itch or itch.”
Is sunscreen or sunblock better?
Both types of sun protection have their pros and cons, says Dr. Psomadakis. Recommend sunscreen for people with sensitive skin or skin conditions, because some of the ingredients in chemical sunscreen can cause irritation or an allergic reaction. But ultimately, the best sunscreen product is the one you like to use and works for your needs.
Dr. Klein gives sunscreen an advantage because it does not have any chemical ingredients that can cause irritation. “Because physical sunscreens sit on the surface of the skin, even the most sensitive skin types tolerate them well,” he explains.
All sunscreens and sunscreens come with an SPF (Sun Protection Factor). The American Academy of Dermatology recommends using an SPF of at least 30, which blocks 97% of UVB rays. But remember, while higher SPF numbers block slightly more of the sun’s UVB rays, no sunscreen can block 100% of them.
What products do dermatologists recommend?
For a general sunscreen for the body, Dr. Jaliman recommends Badger Unscented Sunscreen SPF 30 ($ 13.86; amazon.com). “It contains a very high concentration (18.75%) of zinc oxide, is water-resistant for 40 minutes and is fragrance-free, making it good for people with sensitivity to fragrances,” he says. In addition to that, it contains moisturizing sunflower oil and antioxidant vitamin E.
For sensitive or eczema-prone or rosacea-prone skin, Dr. Jaliman suggests EltaMD UV Physical Broad-Spectrum Sunscreen ($ 26.40; dermstore.com). “It has a high concentration of zinc oxide and titanium dioxide and offers protection against UVA and UVB rays,” she says.
Remember, sunscreen is not just for your body, and dermatologists recommend using it year-round, not just when the sun is out. (Clouds may block some, but not all, UV rays.) Dr. Klein’s favorites for daily use on the face are ISDIN Eryfotona Actinic ($ 55.00; amazon.com) and EltaMD UV Pure Broad-Spectrum ($ 21.20; Dermstore .com).
