Chemical vs Physical Sunscreen: What’s the Difference (and Which One Should You Use)?

Let’s break it down, sun seeker.

We all know sunscreen is non-negotiable (especially if you're chasing the sun on the Gold Coast), but not all SPF is created equal. The two main types — chemical and physical (aka mineral) — work differently, feel different on the skin, and suit different skin needs. Here's everything you need to know before choosing your glow-guard.

What is Chemical Sunscreen?

Chemical sunscreens absorb into the skin and work by absorbing UV rays, converting them into heat, and releasing that heat from the skin.

Common ingredients: avobenzone, octinoxate, oxybenzone, homosalate

Pros:

Lightweight and easy to blend — no white cast
Great under makeup
Often water- and sweat-resistant

Consider if: You want a silky, invisible finish and don’t have overly sensitive skin.

What is Physical (Mineral) Sunscreen?

Physical sunscreens sit on top of the skin and act like a shield, physically reflecting UV rays away from your face.

Common ingredients: zinc oxide, titanium dioxide

Pros:

Immediately effective — no wait time
Less likely to irritate sensitive or acne-prone skin
Often reef-safe and better for the environment

Consider if: You have reactive skin, love a natural formula, or want something gentle enough for daily use.

Which One is Better?

Honestly? It depends on your skin goals and your lifestyle.
Here’s the quick guide:

Skin Type	Best Bet
Sensitive, acne-prone, or post-treatment	Physical (mineral)
Darker skin tones or makeup wearers	Chemical
Kids and babies	Physical
Surfers, swimmers, beach runners	Either — but make sure it’s water-resistant and SPF 50+

Can You Use Both?

Absolutely. Some formulas even combine physical + chemical filters to get the best of both worlds — broad spectrum protection, minimal white cast, and extra staying power.

Sunshe’s Take

We’re all about protecting skin and oceans and would always recommend using a physical sunscreen product if your skin can tolerate it. If not, go for SPF 50+ facial sunscreen, and don't forget your big hat and sunnies. Yes, even for school pick up, hanging out the washing or rushing down for a quick dip.

And keep your eyes peeled for our next product release, we've got some big ideas in store for a daily SPF that doesn't feel like a chore to wear.

Bottom line? Choose the SPF you’ll actually wear, every single day.
(And yes, every day includes cloudy ones too.)
