Introduction

Sunscreen is one of the most recommended skincare essentials by dermatologists worldwide, yet it is also one of the most misunderstood. From confusing SPF numbers to myths about needing sunscreen only on sunny days, there’s a lot of misinformation circulating online and offline. Once you understand what sunscreen really does, it’s easier to protect your skin, keep that fresh, healthy look, prevent sunburn, and lower the chances of skin cancer.

This guide takes the mystery out of sunscreen. We’ll clear up common myths, share the real facts, and show you how to pick and use sunscreen with confidence — whether you’re a skincare pro or just starting to take sun protection seriously.

Why Sunscreen Matters

Sunscreen acts as a shield that helps block or absorb the sun’s harmful ultraviolet (UV) radiation. UV rays come in two main forms:

UVA rays: These penetrate deeply into the skin and are largely responsible for premature aging, wrinkles, and skin damage.

UVB rays: These cause sunburn and play the biggest role in the development of skin cancers.

By using sunscreen every day, you’re guarding your skin against harmful UVA and UVB rays — a small habit that plays a big role in long-term skin health.

Common Myths About Sunscreen (and the Facts Behind Them)

Myth 1: You Only Need Sunscreen on Sunny Days

Fact: UV rays can penetrate clouds, windows, and even clothing. Up to 80% of UV rays reach the earth’s surface on cloudy days, which means your skin is still exposed even when the weather looks gloomy. Wearing sunscreen daily—rain or shine—ensures consistent protection.

Myth 2: Darker Skin Doesn’t Need Sunscreen

Fact: While higher melanin levels in darker skin provide some natural protection, they don’t make anyone immune to UV damage. Darker skin tones can still develop hyperpigmentation, premature aging, and skin cancer. Everyone, regardless of skin tone, benefits from wearing sunscreen.

Myth 3: Higher SPF Equals Unlimited Protection

Fact: SPF (Sun Protection Factor) measures how well a sunscreen protects against UVB rays, but higher isn’t always dramatically better.

1. SPF 30 blocks about 97% of UVB rays.
2. SPF 50 blocks about 98%.
3. SPF 100 blocks about 99%.

No sunscreen blocks 100% of UV rays, and higher SPF doesn’t mean you can stay in the sun longer without reapplying. Reapplication every two hours (or after swimming/sweating) is key.

Myth 4: Makeup With SPF Is Enough

Fact: Foundation or BB cream containing SPF usually provides less protection than advertised because most people don’t apply enough. To get the SPF listed, you’d need to apply a much thicker layer than typical makeup use allows. Always apply a dedicated sunscreen underneath your makeup for full protection.

Myth 5: Sunscreen Causes Vitamin D Deficiency

Fact: Studies show that normal sunscreen use has minimal impact on vitamin D levels. Your body needs very little sun exposure to produce vitamin D, and incidental sun exposure from daily activities usually suffices. Plus, vitamin D can also be obtained through diet and supplements. Protecting your skin should take priority.

First of all, there are two types of sunscreen: chemical-blocking sunscreen and physical-blocking sunscreen. Chemical sunscreens block UV rays by absorbing them into the skin and then releasing them.  Physical sunscreens, meanwhile, function by sitting on top of the skin and reflecting UV rays away from the body or face . There are certain properties associated with both types of sunscreen, which means it’s worth knowing which does what.
