There are plenty of sunscreen myths that can make it harder to know what your skin actually needs. From thinking you do not need sunscreen on cloudy days to believing that a higher SPF means you can skip reapplication, some common misconceptions can lead to less effective sun protection.
Here are several of the most common sunscreen myths, along with what you should know instead.
Myth #1: Sunscreen can replace your moisturizer
Sunscreen is an important final step in your morning skincare routine, but it does not necessarily replace your moisturizer.
Some sunscreens contain hydrating ingredients such as hyaluronic acid, ceramides, lipids, or other moisturizing ingredients and may provide enough hydration for certain skin types. Others are formulated primarily for sun protection and may not provide the moisture your skin needs.
The best approach is to check the product formulation and consider what your skin needs. If your skin feels dry or tight after applying sunscreen, you may benefit from applying a moisturizer first.
At Supriya MD Skincare, products such as HA Physical Tint SPF 44 and Peptide Concealer SPF 50 combine sun protection with skincare ingredients, making them convenient options for adding hydration to your routine.
Myth #2: Sunscreen causes vitamin D deficiency
This is one of the more complicated sunscreen myths because your body does produce vitamin D in response to UVB exposure. However, that does not mean you should intentionally skip sunscreen or spend time in the sun without protection to get your vitamin D.
In everyday life, people are exposed to sunlight in different ways, and sunscreen use has not been shown to reliably cause vitamin D deficiency. Vitamin D can also be obtained through foods and supplements when needed.
If you are concerned about your vitamin D levels, talk with your healthcare provider rather than intentionally increasing your UV exposure. There is no need to trade sun protection for vitamin D.
Myth #3: The higher the SPF, the better
A higher SPF does provide additional protection, but the difference becomes smaller as the SPF number increases. SPF 30 filters approximately 97% of UVB radiation, while SPF 50 filters approximately 98%.
That does not mean SPF 30 is the only appropriate choice. The American Academy of Dermatology recommends choosing a sunscreen with SPF 30 or higher, broad-spectrum protection, and water resistance.
More important than choosing the highest number on the bottle is applying enough sunscreen and reapplying it as directed. Even a very high SPF cannot provide complete protection from UV radiation.
You can also incorporate antioxidant-rich skincare, such as vitamin C, into your routine. Antioxidants can complement your sun protection routine, but they should not be considered a substitute for sunscreen.
Myth #4: You don’t need sunscreen on cloudy days
Clouds may make the sun feel less intense, but they do not eliminate UV exposure.
A simple way to remember: if you are spending time outdoors during daylight hours, sun protection still matters. The AAD recommends applying broad-spectrum sunscreen to exposed skin, even when the weather is not bright and sunny.
It is also important to remember that UVA rays can pass through window glass. That means daily sun protection can be worthwhile even when you are spending time in your car or near windows.
If you are going for a walk, running errands, sitting outside, or spending the day at the beach, make sunscreen part of your routine regardless of whether the sky is clear.
Myth #5: Sunscreen is waterproof
There is no such thing as waterproof or sweatproof sunscreen. Sunscreens can, however, be labeled water resistant if they meet FDA testing requirements.
Water-resistant sunscreens are labeled to indicate whether they maintain their SPF protection for 40 or 80 minutes while swimming or sweating. After that time, or after towel drying, sunscreen should be reapplied.
Even if you are using a water-resistant sunscreen, you should reapply approximately every two hours when outdoors and after swimming or sweating, according to the product’s directions.
Myth #6: Sunscreen ingredients are bad for you and the environment
Concerns about sunscreen ingredients have received a great deal of attention, but it is important to separate specific ingredient concerns from the idea that sunscreen as a whole is unsafe.
Both mineral and chemical sunscreen filters are used in products designed to protect the skin from UV radiation. Mineral sunscreens typically use zinc oxide and/or titanium dioxide, while other sunscreens use organic UV filters.
If you have sensitive skin or find that certain sunscreens sting or irritate your skin, a mineral sunscreen may be a good option to discuss with your dermatologist. The AAD specifically recommends sunscreens containing zinc oxide and titanium dioxide for people whose skin is sensitive to sunscreen.
Environmental concerns can also vary by ingredient, location, and formulation. Rather than assuming that every chemical sunscreen is harmful to the environment, check the regulations and recommendations that apply to the area where you are swimming.
The most important thing is to find a sunscreen you will use consistently. Look for broad-spectrum protection with SPF 30 or higher and water resistance.
Myth #7: Darker skin tones don’t need sunscreen
Melanin provides some natural protection against UV radiation, but darker skin tones are not immune to sun damage or skin cancer.
People with darker skin can still develop skin cancer, and sun exposure can contribute to hyperpigmentation and other visible signs of photoaging. The AAD recommends sun protection for everyone, including people with brown and Black skin.
For people who are prone to hyperpigmentation or melasma, a tinted sunscreen containing iron oxide can provide additional protection from visible light, which can contribute to dark spots.
Your skin tone may influence which sunscreen formulation works best for you, but it does not determine whether you need sun protection.
The sunscreen myths worth leaving behind
The basics of sun protection are actually fairly simple. Choose a broad-spectrum sunscreen with SPF 30 or higher, apply it to exposed skin, and reapply approximately every two hours when outdoors or after swimming or sweating. Wearing protective clothing, seeking shade, and limiting prolonged sun exposure can provide additional protection.
And remember, sunscreen is not just about preventing sunburn. Consistent sun protection can also help reduce your risk of skin cancer and premature skin aging.
