Sunscreen for Beginners: SPF, Broad Spectrum, and Reapplication
Learn what SPF and broad-spectrum protection mean, how much sunscreen to use, and when to reapply for dependable everyday sun protection
8/12/20266 min read
If you're new to skincare, sunscreen is one of the most important products to add to your morning routine.
The label can look confusing at first, but you don't need to understand every ingredient or technical term to make a good choice. For most beginners, start with three things:
Broad-spectrum protection + SPF 30 or higher + consistent application.
Sunscreen works best when combined with other sun-protection habits such as seeking shade, wearing protective clothing, and using sunglasses and a wide-brimmed hat.
Why Is Sunscreen Important?
Sun exposure can contribute to sunburn, premature skin aging, dark spots, and skin cancer.
UVA and UVB are both types of ultraviolet radiation that can damage skin. UVA is associated with premature skin aging and can contribute to skin cancer, while UVB is the primary cause of sunburn.
That's why choosing a broad-spectrum sunscreen is important: broad-spectrum products are designed to protect against both UVA and UVB radiation.
You don't need to wait for a hot or sunny day to think about sun protection. UV exposure can still occur when it's cloudy.
What SPF Actually Means
SPF stands for Sun Protection Factor.
It primarily indicates how well a sunscreen protects against UVB radiation under standardized testing conditions.
For everyday use, dermatologists recommend choosing a sunscreen with SPF 30 or higher.
SPF 30 filters approximately 97% of UVB radiation, while higher SPF products provide somewhat more protection. However, no sunscreen blocks 100% of UVB rays.
A higher SPF also doesn't mean you can stay outside indefinitely without reapplying.
The amount you apply and how consistently you reapply matter.
What Does "Broad Spectrum" Mean?
When you see Broad Spectrum on a sunscreen label, it means the product has passed testing designed to demonstrate protection across both UVA and UVB wavelengths.
This matters because UVB is strongly associated with sunburn, while UVA contributes to premature skin aging and also plays a role in skin cancer.
For a beginner-friendly sunscreen, look for:
Broad Spectrum
SPF 30 or higher
Water resistance if you'll be swimming or sweating
These three label details give you a useful starting point when shopping.
Water-Resistant vs. Waterproof Sunscreen
You may see products labeled Water Resistant (40 minutes) or Water Resistant (80 minutes).
There is no truly waterproof sunscreen.
Water-resistant sunscreen is tested to retain its labeled SPF protection for either 40 or 80 minutes while swimming or sweating.
If you're swimming or sweating heavily, follow the product's instructions for reapplication. You should also reapply after towel drying.
Don't rely on the word "waterproof." That's not an FDA-approved sunscreen labeling claim.
Mineral vs. Chemical Sunscreen
There are two broad categories of sunscreen formulas you'll commonly see.
Mineral Sunscreen
Mineral sunscreens commonly use zinc oxide or titanium dioxide as active ingredients.
They sit on the skin and help protect against UV radiation.
Mineral formulas can be a useful option for people who prefer these active ingredients or have certain sensitivity concerns.
Chemical Sunscreen
Chemical sunscreens use UV filters that absorb ultraviolet radiation.
They can have lightweight textures and may be easier to spread or layer under other skincare products.
Which One Should You Choose?
There's no single sunscreen formula that is best for everyone.
The best option is one you'll actually apply generously and consistently.
Consider:
How the sunscreen feels
Whether it leaves a visible cast
Whether it works with your skin type
Whether it irritates your skin
Whether you like the finish
Whether you'll use it consistently
If one sunscreen feels greasy or uncomfortable, try another texture rather than giving up on sunscreen altogether.
How to Choose Sunscreen for Your Skin Type
Your sunscreen should be comfortable enough that you want to use it every day.
Oily Skin
Consider lightweight lotions, fluids, or gel formulas.
Look for products that feel comfortable without leaving your skin excessively greasy.
Dry Skin
A moisturizing sunscreen may be more comfortable if your skin tends to feel dry or tight.
Look for formulas with hydrating ingredients and a creamier texture.
Combination Skin
A lightweight sunscreen can be a good starting point.
You may prefer a formula that provides hydration without feeling overly heavy in oilier areas.
Sensitive Skin
Look for a simple formula that your skin tolerates well.
If fragrance or certain ingredients tend to irritate your skin, consider a fragrance-free option.
Concerned About Dark Spots?
Tinted sunscreens can be worth considering.
Some tinted formulas contain iron oxides, which can provide additional protection against visible light. This may be particularly useful for people concerned about hyperpigmentation.
How Much Sunscreen Should You Use?
Using too little sunscreen can reduce the protection you actually receive.
For exposed skin on the entire body, approximately one ounce—roughly enough to fill a shot glass—is a commonly used guideline.
For your face and neck, follow the product's directions and apply enough to adequately cover the exposed areas.
Don't forget commonly missed areas such as:
Ears
Neck
Hairline
Scalp part when exposed
Hands
Tops of the feet
Lips with an SPF lip product
The goal is simple:
Cover all exposed skin thoroughly.
When Should You Apply Sunscreen?
For many sunscreen products, the FDA labeling directs users to apply sunscreen before sun exposure. Follow the specific directions on your product.
For a basic morning skincare routine, sunscreen generally goes on after your other skincare products and before makeup.
A simple routine can look like:
Cleanser → Moisturizer → Sunscreen → Makeup
If you're going outdoors, give the sunscreen the time specified on the product label before sun exposure.
When Should You Reapply Sunscreen?
Sunscreen isn't a one-and-done product.
When you're outdoors, the American Academy of Dermatology recommends reapplying approximately every two hours, or after swimming or sweating, according to the product directions.
If you're using a water-resistant sunscreen, follow the labeled 40- or 80-minute water-resistance period when swimming or sweating.
Also reapply after towel drying.
Remember:
☀️ Outdoors → Reapply approximately every 2 hours
🏊 Swimming → Follow the water-resistance instructions
💦 Sweating → Reapply according to the label
🧴 Towel drying → Reapply
5 Common Sunscreen Mistakes
1. Skipping Sunscreen on Cloudy Days
Cloudy weather doesn't eliminate UV exposure.
Make sunscreen part of your normal daytime routine when you're going to be exposed to the sun.
2. Using Too Little
Applying a thin layer may mean you're getting less protection than the SPF number on the label represents.
Apply enough to adequately cover exposed skin.
3. Forgetting Your Neck and Ears
Your face isn't the only exposed area that needs protection.
Remember your ears, neck, hairline, and other exposed areas.
4. Forgetting to Reapply
Sunscreen wears off with time, swimming, sweating, and towel drying.
Keep reapplication in mind whenever you're spending extended time outdoors.
5. Choosing a Formula You Hate
If your sunscreen feels greasy, pills under makeup, leaves an unwanted cast, or irritates your skin, you're less likely to use it consistently.
Try another texture or formula.
The best sunscreen is one you'll actually use correctly and consistently.
Sunscreen Isn't Your Only Protection
Sunscreen is important, but it shouldn't be your only defense against UV exposure.
When possible:
Seek shade
Wear a wide-brimmed hat
Wear protective clothing
Use sunglasses with UV protection
Limit prolonged direct sun exposure
Be especially careful during periods of strong sun
Think of sunscreen as one part of a complete sun-protection routine.
Can Makeup With SPF Replace Sunscreen?
Usually, relying on makeup alone isn't a great strategy for sun protection because most people don't apply enough makeup to achieve the labeled SPF protection.
If you're using makeup with SPF, consider it an additional layer rather than your only sunscreen.
Start with your dedicated sunscreen, then apply makeup afterward if desired.
How to Build a Simple Sunscreen Routine
You don't need a complicated system.
Morning
1. Cleanse
Gently cleanse your face.
2. Moisturize
Use a moisturizer that works for your skin.
3. Sunscreen
Apply broad-spectrum SPF 30 or higher to exposed skin.
During Outdoor Activities
4. Reapply
Reapply approximately every two hours while outdoors and after swimming, sweating, or towel drying according to the product directions.
5. Add Sun Protection
Seek shade and use protective clothing, a hat, and sunglasses when appropriate.
That's it.
Beginner Sunscreen Shopping Guide
Before buying sunscreen, ask yourself:
What am I looking for?
Broad-spectrum protection
SPF 30 or higher
Water resistance if needed
Comfortable texture
Suitable for my skin type
Within my budget
You don't need the most expensive sunscreen on the shelf.
Instead, compare:
SPF
Broad-spectrum protection
Water-resistance rating
Size
Texture
Fragrance
Ingredients
Cost per ounce
Return policy
Choose a product you're comfortable using consistently.
Keep Your Routine Simple
When you're starting out, don't buy ten products at once.
Start with the basics:
Cleanser + Moisturizer + Sunscreen
Give yourself time to establish the habit.
If you decide to add another product later, introduce one new product at a time. This makes it easier to identify what works for you and what may cause irritation.
Keeping track of when you open products can also help you stay organized.
Store sunscreen according to the product's instructions and avoid leaving it exposed to excessive heat.
How to Track Your Sunscreen Routine
If you're trying to become more consistent, keep your tracking simple.
Take a clear photo in consistent lighting before you begin.
Then, instead of constantly checking your skin, review your routine once a week.
Track:
How comfortable the sunscreen feels
Whether your skin feels dry or greasy
Any visible irritation
Whether the sunscreen works under makeup
Whether you're remembering to reapply
Whether the routine is easy enough to maintain
Consistency matters more than creating a complicated spreadsheet.
Final Thoughts
Sunscreen doesn't have to be confusing.
For beginners, focus on the essentials:
Broad Spectrum → SPF 30+ → Apply Enough → Reapply
Then make sun protection part of your everyday routine.
Choose a sunscreen that feels comfortable, works for your skin, fits your budget, and is easy enough to use consistently.
And remember that sunscreen works best alongside other sun-safe habits such as shade, protective clothing, hats, and sunglasses.
