Why We Chose Zinc Oxide for Playsafe SPF 40+
Share
Sunscreen is the one product where the "what's inside" question matters most — because it stays on skin all day, in the heat, through sweat and swims. When we formulated Playsafe SPF 40+, we started with one question: what's the simplest, most skin-respectful way to protect young skin from the sun?
The answer was zinc oxide. Here's why.
Mineral vs Chemical UV Filters: The Difference
There are two broad families of sunscreen filters:
- Mineral (physical) filters — like zinc oxide — sit on the skin's surface and block or scatter UV rays.
- Chemical (organic) filters — like avobenzone or octocrylene — absorb into the upper layers of skin, absorb UV radiation and convert it to heat.
Both types are approved and used in sunscreens worldwide. But for a product designed for young skin, we preferred the mineral route: zinc oxide stays on the surface doing its job, rather than interacting with skin to do it. For developing skin, "sits on top" felt like the right philosophy.
Why Zinc Oxide Specifically
Zinc oxide is one of the few single filters that covers both UVA and UVB on its own — broad-spectrum protection from one well-understood mineral. It's been used in skincare and nappy creams for decades, which means there's a long history of use on sensitive, young skin.
Playsafe SPF 40+ uses zinc oxide as its UV filter, supported by skin-comforting ingredients like colloidal oatmeal, niacinamide and calendula — because sun protection shouldn't come at the cost of skin comfort.
Why We Skipped Silicones, Methicones and Heavy Polymers
Here's something most sunscreen labels won't tell you: many formulas rely on silicones (like dimethicone), methicones and heavy film-forming polymers to make the product feel silky, spread easily and stay put. They're effective at that job — but they work by forming a persistent film on skin.
For young skin, we weren't comfortable with that trade-off. Kids' skin is thinner and more permeable than adults', and it needs to breathe, sweat and regulate temperature — especially in UAE heat. Heavy occlusive films can trap heat and sweat against skin, which is the opposite of what you want on a playground in August.
So Playsafe is formulated without silicones, methicones or heavy polymers. Instead, we use lighter plant-derived emollients — hemisqualane, olive squalane, caprylic/capric triglyceride — to get a comfortable, wearable texture. It feels like skincare, not like armour.
Safety-First Formulation, Start to Finish
The zinc oxide decision is part of a bigger picture. Every FOMO product follows the same label promise:
- Pediatrician tested
- Hormone Disruptor Free
- pH Balanced
- No Silicons & Sulphates
- Allergen-Free Fragrance
That "hormone disruptor free" line matters especially in sun care, because some chemical UV filters have been the subject of ongoing scientific discussion around endocrine activity. By choosing zinc oxide and keeping the rest of the formula clean, we sidestep the debate entirely.
A Note on Realistic Expectations
No sunscreen blocks 100% of UV rays, and no formula replaces smart sun habits. Playsafe SPF 40+ is designed to be part of a routine: apply generously before sun exposure, reapply regularly (especially after swimming or sweating), and pair it with shade, hats and common sense during peak hours.
How much is "generous"?
Most people — kids especially — under-apply sunscreen. A useful rule of thumb: two finger-lengths of product for the face and neck, and don't forget ears, the back of the neck and the tops of feet (classic missed spots). For the body, think a shot-glass-sized amount for full coverage. It sounds like a lot because it is — that's how SPF testing is done, so that's how it works best.
Reapplication is the real SPF
The first application gets you started; reapplication keeps you protected. Every two hours in continuous sun, and immediately after swimming, heavy sweating or towelling off. Set a phone timer if you have to — "SPF o'clock" is a perfectly respectable family ritual.
Don't bake it in the car
One practical tip: don't store sunscreen in a hot car or in direct sun for hours. Heat can degrade formulas over time. A cool, shaded spot — the beach bag in the shade, not on the dashboard — keeps it performing as intended.
We can't promise your kid will sit still for reapplication — that's above our pay grade. But we can promise the formula itself was built with young skin's safety as the starting point, not an afterthought.
