Sunscreen labels are confusing. And not by accident.
There is actually a lot to understand before deciding what is best for your skin. Without that knowledge, most of us cycle through bottle after bottle, guided by hype, word of mouth, price, or honestly — whether the packaging looks pretty on the bathroom shelf.
But really? In 2026?
Why Don’t Brands Just Say Mineral or Chemical?
What frustrates me most about sunscreen labels is this: why don’t brands simply state whether their product uses mineral or chemical filters?
The answer is straightforward. It is not a mandatory requirement by regulatory bodies like the FDA or HSA in Singapore — so many brands simply leave it out.
This matters because mineral and chemical filters work very differently.
In plain English: mineral filters reflect UV rays away from your skin. Chemical filters absorb UV rays into your skin and dissipate the energy as heat beneath the surface.
Knowing this should be your choice to make — especially if you have sensitive skin, contact allergies, or young children.
Mineral filters — primarily zinc oxide and titanium dioxide — are generally considered the safer option for reactive skin. The trade-off is texture: they can feel heavier, greasier, and may leave a white cast. Chemical filters, on the other hand, are lightweight and cosmetically elegant — blending seamlessly into skin. Common chemical filters include oxybenzone, avobenzone, octinoxate, Tinosorb S, Tinosorb M, and Uvinul A, among others.
Yet walk into any beauty store today and you will find the majority of sunscreens do not clearly disclose which type of filter they use. I have genuinely been tempted to bring a magnifying glass to zoom into the INCI list on the back of the box — because most brands don’t print it on the bottle.
The “Mineral” Label Isn’t Always What It Seems
Here’s something worth knowing: many products marketed as “clean mineral sunscreens” actually contain SPF boosters such as butyoctyl salicylate and tridecyl salicylate — which are chemical filters. This allows brands to lead with a mineral claim while quietly including chemical actives in the formula.
As a consumer, it’s worth checking the full INCI list rather than relying on front-of-pack claims alone.
On the topic of chemical filters and safety concerns — there has been significant debate online, and some older generation filters that were once widely approved have since come under scrutiny. Some dermatologists have pushed back on what they consider misinformation, while others have raised legitimate questions about long-term use.
I am not a scientist, and I won’t pretend to be. What I will say is this: wearing sunscreen — any sunscreen — is better than not wearing one. 90% of visible skin ageing is caused by sun exposure. Protect yourself, and make the most informed choice you can.
Decoding the Numbers: SPF, PA+++ and What They Actually Mean
These terms are mandatory on labels — and they matter.
SPF tells you how long you are protected from UVB rays — the rays responsible for burning. If your unprotected skin burns in 10 minutes, SPF 30 means 300 minutes of protection. SPF 30 blocks approximately 97% of UVB rays, while SPF 50 blocks around 98%. The difference is smaller than most people expect.
PA+++ is an Asian rating system, originating in Japan, that measures protection against UVA rays — the ultraviolet ageing rays that penetrate deeply into the skin, break down collagen, and contribute significantly to visible ageing. Despite being arguably more important than SPF for long-term skin health, PA ratings are frequently overlooked.
The limitation of the PA system is that it does not specify a threshold the way the EU’s UVA circle standard does — which requires UVA protection to be at least one-third of the stated SPF value.
Reading the INCI List Like a Pro
INCI stands for International Nomenclature of Cosmetic Ingredients — a standardised naming system designed to ensure safety and transparency across markets. Ingredients must be listed in descending order of concentration, down to 1%. Everything below 1% can legally appear in any order.
A few things to keep in mind:
On efficacy claims: When a brand states SPF 50 PA++++, it implies strong protection — but the same claim from two different brands does not guarantee the same level of protection. Efficacy testing is required before a product enters the market, but in Singapore, HSA operates on a self-regulated compliance basis, meaning testing reports are not routinely reviewed unless a concern is raised. As a consumer, it is worth looking for brands that voluntarily publish their third-party testing results.
On functional ingredients: Many sunscreens now include skin-benefit ingredients like niacinamide or hyaluronic acid. If you spot these listed near the bottom of the INCI list, the concentration is likely too low to deliver a meaningful benefit. The INCI order tells you a lot about where a brand has chosen to invest in its formula.
What About “Dermatologist-Tested” and “Hypoallergenic”?
These terms sound reassuring — and they can be, when backed by legitimate data. Claims like dermatologist-tested, hypoallergenic, and non-comedogenic should be supported by third-party testing conducted by accredited labs.
As the beauty industry continues to grow and evolve, it is more important than ever to read beyond the front of the pack. Ask questions. Look for transparency. Support brands — of any size — that are willing to show their work.
Being an informed consumer is the best skincare decision you can make.
Suncare, done right.
