Figuring out which sunscreen is best for you might come down to what formulations you prefer.
You've probably heard terms like "mineral" and "chemical" sunscreens being thrown around, often with strong opinions attached.
We're firm believers that you should choose an SPF that not only works for you, but also one that you’ll enjoy using everyday.
In this article, we’ll break down the differences, myths, and benefits of mineral and chemical sunscreens to help you make the best decision for your skin.
What's the difference Between Mineral and Chemical Sunscreens?
The main difference between mineral and chemical sunscreens lies in the UV filters used, which help protect our skin from harmful UVA and UVB rays.
What Are UV Filters in sunscreen?
UV filters are the active ingredients in sunscreen that help either absorb and/or block harmful UV rays from the sun. These filters are divided into two types:
It’s worth noting that in Australia, sunscreen formulations are strictly regulated by the Therapeutic Goods Administration (TGA).
The TGA ensures all approved sunscreens are not only safe, but also exceed global safety standards.

Mineral sunscreens are also known as “physical” sunscreens or “inorganic” sunscreens.
Mineral sunscreens contain either zinc oxide, titanium dioxide, or a combination of both.
They absorb UV rays and convert them into heat, helping prevent skin damage from UV rays.
Mineral sunscreens also scatter a small percentage of rays, about 4%, which has led to the common myth that Mineral SPFs bounce away UV rays.
People often associate mineral sunscreens with soothing properties and a more natural formulation.
This can make them a popular choice for those with sensitive or reactive skin.
However, mineral sunscreens can have drawbacks.
Some formulations can leave a white cast on some skin tones, due to the UV filter being a white powder pigment in its raw form.
To balance out the cast, many mineral formulas include a tint using iron oxides (which have their own skin benefits too).
Even with a slight tint, there are still limitations in what undertones and shades can be achieved.

Chemical sunscreens are also known as “organic” sunscreens.
Chemical sunscreens are often preferred for their lightweight, airy formulations.
They absorb UV rays and convert them into heat, helping prevent skin damage from the sun.
Some people may be sensitive to specific chemical filters, but if the sunscreen is formulated with sensitive skin in mind, this isn’t usually an issue.
Chemical sunscreens typically blend easily without leaving a white cast, although some chemical filters can still leave a residue on deeper skin tones.
Which is Better for Sensitive Skin: Mineral or Chemical SPF?
The answer is simple: Whichever you enjoy more that aligns with your skin's needs and preferences.
Mineral sunscreens are often recommended for sensitive skin due to the calming properties of zinc oxide.
This makes them ideal for people with reactive, acne-prone or easily irritated skin.
On the other hand, some sensitive skin types prefer chemical sunscreens because of their lightweight texture.
This typically makes chemical sunscreens a better fit for people who struggle with heavier textures and layers.
Do mineral or chemical sunscreens leave a white cast?
Both types have the potential to leave a white cast.
Mineral sunscreens are more prone to leaving a white residue because of the mineral UV filter’s raw form: a white powder.
To balance this out, mineral sunscreens are often tinted to help them blend more seamlessly across different skin tones.
For deeper skin tones, more intensely pigmented products like our BeautyScreen™ or CabanaGlow™ are often necessary for mineral sunscreen options.

Can You Layer Mineral and Chemical Sunscreens?
Yes, you can!
When it comes to reapplying sunscreen throughout the day, it is best to use the same formula you applied in the morning for better layering and results.
However, if you don’t have your original sunscreen on hand, it’s okay to layer a different one.
Whether it’s mineral or chemical, consistency with SPF application and reapplication is the most important factor in protecting your skin.
We also have advice on how to reapply sunscreen over makeup, which you can explore further in our guide here.
Which Type of SPF is Better for Daily Use?
There’s no universal rule for whether mineral or chemical sunscreen is better for daily use.
It ultimately depends on your skin type, lifestyle, and personal preferences.
Here are some general guidelines people use to help them find their best fit, based on feedback from our customers:
Sensitive Skin:
Many people with sensitive or acne-prone skin lean towards mineral sunscreens, finding zinc’s calming properties beneficial.
Oily or Combination Skin:
Lightweight chemical formulations are often preferred for shiny and oily skin, as they can provide a non-greasy, weightless finish.
Deeper Skin Tones:
People with deeper skin tones may prefer chemical sunscreens or tinted mineral sunscreens for their ability to blend without leaving a white cast.
Summing it up
The best sunscreen is the one you’ll use consistently. If you’re worried about safety, the extensive testing and regulation conducted by the Australian TGA should give you peace of mind.
Both mineral and chemical sunscreens offer excellent protection when used correctly, and your choice should ultimately be guided by what feels good on your skin.
