I used to grab the nearest sunscreen at the chemist, thinking SPF was just SPF. Honestly? I didn’t even think about skin type. But after a few surprise breakouts, a chalky white cast in every selfie, and one painful sunburn despite wearing sunscreen, I realised not all SPF is created equal.
If you’re confused about sunscreen for your skin type, I get it. It can feel like decoding skincare in a foreign language. But trust me, when you find the right one? Game-changer. Here’s what I’ve learned—plus a few hard-earned lessons along the way.
What Sunscreen Actually Does (And Why It Matters More Than You Think)
You know that warm, golden sunlight we chase on beach days? It’s not all glow and vibes. Hidden inside those rays are UVA and UVB radiation—two invisible threats that mess with our skin more than we realise.
UVA rays are the sneaky ones. They dive deep, contributing to early signs of ageing like wrinkles, dark spots, and that dull, uneven texture. UVB rays? They’re more aggressive—causing redness, peeling, and the classic sunburn. Both can lead to skin cancer over time, and the scary part is: damage happens even on cloudy days.
Sunscreen forms an invisible shield. It either absorbs or deflects those harmful rays, depending on the type. But here’s what surprised me: sunscreen isn’t a set-it-and-forget-it deal. It fades. Sweat, sun, time—it all wears it down.
Quick Win: Reapply every 2–3 hours. Even if you’re indoors near windows, or it’s cloudy out. UV rays don’t take a day off.
Know Your Rays: UVA vs. UVB (And Why Both Matter)
One of the easiest—and most important—things I learned about sunscreen is how to tell UVA and UVB rays apart. I like to keep it simple: UVA is for Ageing, and UVB is for Burning. UVA rays are the sneaky culprits behind wrinkles, dark spots, and that gradual loss of firmness, while UVB rays are the ones that cause visible sunburn and redness—often when it’s already too late. Both types of radiation are harmful, both can increase the risk of skin cancer, and both are constantly present, even on cloudy days. That’s why finding a broad-spectrum sunscreen isn’t just a nice bonus—it’s essential. It’s the only type that shields you from both UVA and UVB rays. And no, “broad-spectrum” isn’t just clever branding—it’s your skin’s best defence. Always look for that label before you buy.
Decoding Sunscreen Types: Chemical vs. Physical
I used to think sunscreen was just… sunscreen. Then I learned there are two main types, and they work very differently.
1. Chemical Sunscreen (a.k.a. Organic Filters)
These soak into your skin and absorb UV rays, converting them into a tiny bit of heat. They often feel lighter and invisible on the skin, with no white cast. But they can irritate sensitive skin or sting around the eyes.
Common ingredients: oxybenzone, avobenzone, octocrylene. Some people (including me) find oxybenzone irritating, so I now check labels like a hawk.
2. Physical Sunscreen (a.k.a. Mineral or Inorganic Filters)
These sit on top of your skin and reflect UV rays. The OGs of this category are zinc oxide and titanium dioxide. They’re usually gentler and safer for sensitive skin, especially great for kids.
But here’s the catch: they can feel thicker and leave a slight white cast. I found that rubbing it in really well (or choosing a tinted version) makes a big difference.
Pro Tip: If your skin stings or breaks out with sunscreen, switch to mineral-based. It’s usually a skin-saver.
How to Choose Sunscreen for Your Skin Type
This is where it gets personal. Not all sunscreens vibe with all skin types—and I learned that the hard way.
✔ Oily or Acne-Prone Skin
Go for: lightweight, oil-free formulas. Gel-based or water-based SPFs feel breathable and won’t clog pores. Look for “non-comedogenic” on the label.
Watch out for: greasy finishes and coconut oil in the ingredients list (sneaky pore clogger).
✔ Dry or Dehydrated Skin
Go for: hydrating SPFs with ingredients like hyaluronic acid or ceramides. Cream-based formulas often give that extra moisture hit.
Avoid: alcohol-based sprays or gels—they can make dryness worse.
✔ Sensitive Skin
Go for mineral sunscreens with zinc oxide or titanium dioxide. Fewer ingredients = fewer chances of irritation.
Avoid: fragrances, oxybenzone, and avobenzone if your skin tends to react.
✔ Combination Skin
Go for: something lightweight but moisturising. I’ve found a matte mineral sunscreen with a hint of tint works beautifully—no shine, no dry patches.
Quick Win: Always do a patch test—on your neck or jawline—before slathering anything new all over your face.
What Not to Do When Picking Sunscreen
Let’s talk about common mistakes. I’ve made a few of these, and I bet you have too.
1. Skipping the Ingredients List
I once picked a sunscreen that promised “natural glow,” only to break out for a week. Now I scan the label like it’s a dating profile. Know your triggers and dodge them.
2. Forgetting the Expiry Date
Sunscreen isn’t wine—it doesn’t age well. Expired formulas lose potency and may even harm your skin. Always check the date.
3. Using Sunscreen-Bug Repellent Combos
Seems convenient, right? But here’s the thing: repellents have strong chemicals, and sunscreen needs to be reapplied often. Reapplying = reloading that repellent unnecessarily onto your skin. Not ideal.
Pro Tip: Keep sunscreen and bug spray separate. Use them strategically, not together.
Key Takeaways
Choosing the right sunscreen isn’t just about glowing skin—it’s a long-term investment in your skin’s health. It’s your front-line defence against premature ageing, sunburn, and more serious concerns like skin cancer. Once you understand your skin type and what it responds to, finding the right formula becomes far less overwhelming and way more effective. The essentials? Always reach for broad-spectrum protection to guard against both UVA and UVB rays. Pick a texture and ingredient list that suits your specific skin needs—whether that’s oil-free, hydrating, or fragrance-free. Reapply diligently every couple of hours, and don’t be fooled by overcast skies or cooler seasons—SPF isn’t seasonal, it’s daily skincare non-negotiable.
Final Thoughts: Protect the Skin You’re In
We only get one skin. And with UV damage lurking 365 days a year, sunscreen isn’t optional—it’s your daily armour. Whether you’re walking the dog, working by a sunny window, or dancing at a beach wedding, the right SPF makes all the difference.
Start today. Your skin will thank you five years from now.
