Sunscreen Label Guide: How to Read and Understand It

Remember the days of picking up a sunscreen bottle at a store, flipping it around and trying to decode the label in two minutes? Now that most of us shop online, especially for skincare, it becomes even more important to know what you're looking at. You don’t get to feel the texture or test the scent, and you rely entirely on the label. 

At CodeSkin, where ingredient transparency is front and centre, reading labels becomes easier but still requires a little know-how. This guide is here to help you understand those terms and symbols, so you can choose the right product with confidence.

Why Reading a Sunscreen Label Matters

Sunscreen is one of the most important steps in any skincare routine, and choosing the right one starts with understanding its label. The terms, percentages and symbols are more than just marketing—they are indicators of how well a product will protect your skin. 

The label breaks down active ingredients and their concentrations, usage directions and safety warnings. Misreading or ignoring this information can mean using a product that doesn’t suit your skin or lifestyle. A label tells you exactly what you’re putting on your face, so it's worth reading carefully.

Key Terms on a Sunscreen Label Explained

• SPF (Sun Protection Factor)

Tells you how well the sunscreen protects against UVB rays, which cause sunburn. SPF 30 is standard for daily use, but higher numbers are better for prolonged exposure.

• Broad Spectrum

Indicates that the sunscreen protects against both UVA and UVB rays. UVA rays cause skin aging and UVB causes sunburn—both contribute to skin cancer.

• PA Rating

Common in Asian sunscreens, this measures UVA protection. PA+++ or PA++++ offers high to very high defence.

• Water-Resistant

Means the sunscreen will maintain its SPF for 40 to 80 minutes while swimming or sweating. It’s not waterproof, so you’ll still need to reapply.

• Mineral vs. Chemical

Mineral sunscreens (like zinc oxide) sit on top of the skin and reflect rays. Chemical ones absorb UV and convert it to heat, often feeling lighter on the skin.

• Non-Comedogenic

This means the product is less likely to clog pores. It’s especially helpful for acne-prone skin.

• Fragrance-Free

Good for sensitive skin, this means no added perfumes. It doesn’t mean the product is completely scentless, but it avoids known irritants.

Understanding the Sunscreen Drug Facts Label

The sunscreen drug facts label is usually printed on the back and resembles a nutrition chart. It lists the active ingredients with their specific percentages, which helps you know what’s doing the actual UV-blocking work. You’ll also find directions for use, like how much to apply and how often to reapply, plus any safety warnings. 

Some products include inactive ingredients, too, which can offer hydration or improve texture. By learning how to read this panel, you're better equipped to choose a sunscreen that actually performs well and fits your routine.

How to Choose the Right Sunscreen Based on the Label

With so many terms and claims, picking the right sunscreen can feel overwhelming. That’s why brands like CodeSkin make it easier with full ingredient transparency, clearly listed certifications and detailed clinical testing. 

Whether you prefer a lotion, spray or gel, CodeSkin offers sunscreens for different skin types and needs. They’re vegan, reef-safe and free from harsh filters like oxybenzone or octinoxate. Plus, the presence of skin-loving ingredients like Vitamin E and B5 makes them a great choice for anyone looking for more than just sun protection.

Common Misconceptions About Sunscreen Labels

1. Waterproof means you’re covered all day

Many people assume that if a sunscreen says “waterproof,” it will protect them no matter what. But no sunscreen is truly waterproof—at best, it’s “water-resistant,” and even then, it only lasts for 40 to 80 minutes in water or sweat before you need to reapply.

2. Higher SPF means stronger and longer protection

SPF 100 sounds better than SPF 50, but beyond SPF 50+, the increase in protection is minimal. It doesn’t mean you can skip reapplying or stay in the sun longer—it just offers a slightly higher UVB shield, not a time extension.

3. Broad spectrum equals high SPF

Some believe “broad spectrum” is another way to say the SPF is high, but they are not the same. SPF only tells you how well the product protects against UVB rays, while “broad spectrum” means it also covers UVA rays, which cause ageing and long-term skin damage.

4. Broad spectrum guarantees full UVA protection

While broad-spectrum sunscreens must meet certain standards, not all offer equal UVA protection. The label confirms UVA coverage exists, but not how strong it is, so don't assume all broad-spectrum products work the same.

Understanding Sunscreen Labels for Informed Choices

Now that you know how to read a sunscreen label, you're better prepared to make smart, skin-friendly choices. Don't just shop by SPF, look at the full picture. Whether you’re buying online or in-store, understanding labels means you’ll always pick what’s best for your skin.
