Sunscreen Myths That Need to Be Busted

Sunscreen is one of the most effective tools we have for protecting our skin from premature aging, sunburn, and skin cancer. Yet, despite its importance, there are many myths surrounding sunscreen that lead people to use it incorrectly or skip it altogether. Today, we’re breaking down some of the most common sunscreen myths so you can stay protected and make the most of your skincare routine.

Myth #1: SPF in Makeup Is Enough Protection

It’s common to find SPF in makeup products like foundation, BB creams, or powders. While it’s helpful to have some SPF in your makeup, it’s rarely enough to provide complete protection.

The Truth: Most makeup products don’t contain a high enough SPF to protect against UV rays effectively, and we usually don’t apply enough of them to get the labeled SPF protection. Sunscreen should be applied in a thick, even layer—something we rarely do with makeup. If you rely on SPF in makeup alone, you’re likely getting far less coverage than you need.

Solution: Use a dedicated broad-spectrum sunscreen as your final skincare step, even if your makeup contains SPF. This way, you’re getting full protection.

Myth #2: You Don’t Need Sunscreen Indoors

Some people believe that they only need sunscreen outdoors, but UV rays can reach you even inside. UVA rays, in particular, can penetrate windows and affect your skin.

The Truth: If you’re sitting near a window or in a room with lots of natural light, UVA rays can still reach you. UVA rays are responsible for skin aging and can contribute to skin cancer, even if you’re not directly in the sun.

Solution: Apply sunscreen each morning, whether you’re staying indoors or going outside. If you’re working near a window or plan to spend time in the car, applying SPF is still essential.

Myth #3: Darker Skin Tones Don’t Need Sunscreen

There’s a common misconception that people with darker skin tones don’t need sunscreen because they have more natural melanin, which provides some protection.

The Truth: While melanin does offer some protection, it’s not enough to prevent skin damage from UV rays. People with darker skin are still susceptible to sunburn, skin aging, and skin cancer. In fact, skin cancer is often diagnosed at later stages in darker skin tones, which can make it more dangerous.

Solution: No matter your skin tone, sunscreen is essential for keeping your skin safe and healthy.

Myth #4: SPF 100 Offers Double the Protection of SPF 50

When we see a high SPF number, it’s easy to assume that it provides significantly more protection. But SPF doesn’t increase linearly, and SPF 100 isn’t vastly more protective than SPF 50.

The Truth: SPF 30 blocks around 97% of UVB rays, SPF 50 blocks about 98%, and SPF 100 blocks about 99%. The difference between SPF 50 and SPF 100 is minimal, and it’s not double the protection. Additionally, higher SPF sunscreens can give a false sense of security, leading some to skip reapplication.

Solution: Choose an SPF of 30 to 50 and focus on applying enough sunscreen and reapplying every two hours if you’re outside or after swimming or sweating.

 Myth #5: Sunscreen Causes Acne

Many people avoid sunscreen because they worry it will clog their pores and cause breakouts. While some formulas can feel greasy or heavy, there are plenty of non-comedogenic sunscreens designed for acne-prone skin.

The Truth: Not all sunscreens are created equal. Some thicker, oil-based sunscreens may contribute to breakouts, but there are many lightweight, non-comedogenic options available today that won’t clog pores.

Solution: Look for sunscreens labeled as “oil-free,” “non-comedogenic,” or specifically designed for sensitive or acne-prone skin. Gel-based or mineral sunscreens are often lighter and may feel more comfortable if you’re prone to breakouts.

Myth #6: Waterproof Sunscreen Means You Don’t Need to Reapply

Waterproof sunscreens are designed to stay on your skin longer if you’re sweating or swimming, but they’re not entirely water-resistant, and they still wear off over time.

The Truth: No sunscreen is 100% waterproof. Waterproof or “water-resistant” sunscreens will protect you for up to 40 or 80 minutes of water exposure, but you’ll still need to reapply it after that time if you’re swimming, sweating, or towel-drying.

Solution:Follow the instructions on the label and reapplying every two hours if you’re outside or after swimming or sweating.
