How to choose a sunscreen for your face

"What is the best sunscreen for my face?" is one of the most common skincare questions. Skinli's answer has no brand name in it. The words on a sunscreen label are set and tested under FDA rules, so they tell you far more than the name on the front. This guide explains what to look for, word by word, how to match a sunscreen to your skin, and how to use it so it gives the protection on the label. It follows the advice of the American Academy of Dermatology (AAD), the FDA and the NHS, and it matches the sunscreen step in Skinli's own plan.

The short answer

The AAD asks for three things on the label:

1. Broad Spectrum
2. SPF 30 or higher
3. Water Resistant (40 or 80 minutes)

Then add one of these if it fits your skin:

• Non-comedogenic or "won't clog pores," if you get breakouts
• Tinted, with iron oxide, if you have medium to dark skin or dark spots
• Mineral (zinc oxide or titanium dioxide), if your skin is sensitive

Beyond that, the AAD's own rule is the most useful one: "The best type of sunscreen is the one you will use again and again."

Why the label matters more than the brand

In the United States, sunscreen is regulated as a drug. The FDA says this means sunscreens "must satisfy the safety and efficacy standards for nonprescription drug products." Federal labeling rules (21 CFR 201.327) set the exact wording of the main claims on the front of the tube and the tests behind each one. A product may print "Broad Spectrum SPF 30" only if it passed the SPF test on people and the broad spectrum test in the lab. It may print "Water Resistant (80 minutes)" only if it kept its SPF after 80 minutes in water.

Some words are banned. The rules call "sunblock," "sweatproof" and "waterproof" false or misleading. The FDA also bans any claim of "protection for more than two hours without reapplying."

Other words have no official meaning at all. The AAD says the FDA has not defined "sport," "baby," "sensitive skin" or "reef safe" for sunscreen. Treat those as hints, and read the tested claims and the Drug Facts box instead.

Label word 1: Broad Spectrum

Sunlight contains two kinds of ultraviolet light that harm skin. UVB mostly burns. UVA ages skin, causing wrinkles and age spots, and the AAD says it can pass through window glass. The AAD says overexposure to either can lead to skin cancer.

"Broad Spectrum" means the product protects against both. The FDA says only broad-spectrum sunscreens with SPF 15 or higher "help protect against the UV rays that increase the risk of skin cancer and early skin aging caused by the sun." A sunscreen that is not broad spectrum, or has an SPF below 15, must carry a warning that it has been shown only to help prevent sunburn.

Label word 2: SPF 30 or higher

SPF stands for sun protection factor. The FDA says it "indicates the level of sunburn protection provided by the sunscreen product." The AAD gives the figures: SPF 15 filters out 93 percent of the sun's burning rays and SPF 30 filters out 97 percent. Higher numbers filter a small amount more, and none reach 100 percent.

The FDA's minimum for lowering skin cancer risk is SPF 15. The AAD and the NHS both recommend SPF 30 or higher, and Skinli's plan uses SPF 30 or more.

Two facts about SPF surprise people. First, SPF 50 lasts the same length of time on the skin as SPF 30; the AAD says both need reapplying every two hours outdoors. Second, SPF measures an amount of sun. The FDA says it has no direct link to time spent outside, because the strength of the sun changes with the time of day and the place. Our guide on how sunscreen works and what SPF means explains the tests.

Label word 3: Water Resistant

Water resistance tells you how long the SPF lasts while you swim or sweat. The label must say either 40 or 80 minutes. The AAD includes water resistance in its advice for all sunscreen, and says it keeps sunscreen on wet or sweaty skin for a while before you need to reapply. The FDA says no sunscreen is waterproof and "all sunscreens eventually wash off."

Matching a sunscreen to your skin

Acne-prone or oily skin

Look for "non-comedogenic" or "won't clog pores." The AAD says products with this label do not cause breakouts in most people, and the UK's NICE acne guideline advises people with acne to avoid oil-based and comedogenic sunscreens. The AAD says gels suit oily skin. Our guide to sunscreen for acne-prone skin covers this in detail.

If you use an acne treatment, sunscreen matters more. The AAD says some acne medicines make skin more sensitive to the sun, and it lists sun protection as part of using a retinoid such as adapalene. See how to start adapalene without irritation for how the two fit together.

Dry skin

The AAD says creams "are best for dry skin and applying on the face." A moisturizer underneath helps too.

Sensitive skin

The AAD recommends mineral sunscreen, made with zinc oxide, titanium dioxide or both, for sensitive skin. The FDA has proposed that sunscreens with up to 25 percent of these two ingredients are generally recognized as safe and effective. Our guide to mineral vs chemical sunscreen compares the two groups.

Medium to dark skin, or dark spots

The AAD says the darker your skin tone, the higher the risk that ultraviolet rays and visible light will cause dark spots. It recommends a tinted sunscreen with iron oxide, which protects against visible light, in a shade that blends with your skin to avoid a white cast. Iron oxide appears in the inactive ingredients list. Our guide on whether Black people need sunscreen explains more.

How much to use on your face

Most people use too little. The SPF on the label comes from a test that uses 2 milligrams of sunscreen per square centimeter of skin, a thick layer. The AAD says many people apply only 20 to 50 percent of the amount needed.

For the face, the AAD says to use at least 1 teaspoon, enough to cover the length of your index and middle fingers. Skinli's plan uses the same measure: two lines of sunscreen, one on each of two fingers, for the face and neck. It feels like a lot the first time.

The FDA lists spots people often miss: ears, nose, lips, the back of the neck and along the hairline. For lips, the AAD suggests a lip balm with SPF 30 or higher.

When to apply and reapply

Sunscreen is the last step of the morning routine, after cleanser and moisturizer. Our guide on what order to apply your acne products shows the full order.

Put it on 15 minutes before you go out. Every U.S. sunscreen label must give that direction. Reapply at least every two hours outdoors, and after swimming, sweating or towel drying. Our guide on how often to reapply sunscreen covers the details.

Wear it on cloudy days. The FDA says up to 80 percent of the sun's ultraviolet rays can get through clouds.

Buying and storing a sunscreen

Check the expiration date when you buy. The FDA says a sunscreen with no date should be treated as expired three years after purchase. Keep it out of hot cars and direct sun, because the AAD says heat speeds up how fast the ingredients break down. Our guide on whether sunscreen expires explains more.

Choose a lotion, cream or gel for the face. The FDA says spray sunscreens should never be applied directly to the face.

What changed in 2026

The FDA made two changes to the list of sunscreen ingredients this year. In June 2026 it added bemotrizinol, the first new sunscreen ingredient since the late 1990s, which it says protects against both kinds of ultraviolet light and has low absorption through the skin. In September 2026 it removed PABA and trolamine salicylate, two old ingredients that it says no current U.S. product contains. The FDA has also asked makers for more safety data on 12 chemical ingredients, and says that request is not a finding that they are unsafe. Our guide on whether sunscreen is bad for you covers the safety research.

Sunscreen is one part of sun protection

The FDA says "no sunscreen completely blocks UV radiation." The AAD's full advice adds shade between 10 a.m. and 2 p.m., a wide-brimmed hat, sunglasses with UV protection and sun-protective clothing.

Daily sunscreen has a measured payoff. A 2013 randomized trial in Australia, published in the Annals of Internal Medicine, found that people who used sunscreen every day had 24 percent less skin aging over four and a half years than people who used it when they chose.

Skinli's starter acne routine puts sunscreen into a simple three-step morning, and the complete acne skincare routine explains why it matters while you treat acne. See a doctor for any spot on your skin that is new, growing, bleeding or changing, and for a sunburn that blisters over a large area or comes with fever or chills.
