Inside the science: How we built Supernatural SPF 50+ mineral sunscreen 

At Antipodes, we set out to create an uncompromising mineral sunscreen – one that truly delivers broad spectrum SPF 50+ protection while staying true to our natural skincare philosophy. Here’s how Supernatural SPF 50+ Ceramide Silk Facial Sunscreen was formulated, and why it stands apart from the mineral sunscreens you may have questions about.

Our research led us to design a modern (non-nano) zinc oxide formulation built from natural, oil-origin compounds with a mid-weight, waxy texture. Crucially, the formula is completely free from water – what scientists call anhydrous.

This decision avoids many of the problems seen in water-based sunscreens, such as:

• Uneven distribution of zinc oxide, which can lead to inconsistent SPF coverage across the skin.
• Sheer or overly light textures that may compromise protection and reduce uniformity of coverage.

By removing water entirely, we created a formulation that maintains integrity, stability, and uniform performance, ensuring every application delivers reliable broad spectrum protection.

It’s important to distinguish between moisturisers with added SPF and a primary function sunscreen like ours. Moisturisers with SPF typically contain a high percentage of water to carry their active ingredients, with UV filters or blockers added in. These cannot be labelled as ‘broad spectrum UVA & UVB protection’.
In contrast, our Supernatural SPF 50+ was purpose-built as a sunscreen first and foremost – designed to defend skin against both UVA and UVB rays.

• UVB rays are short wave rays that bounce off the skin’s surface and cause burning. A blocker is essential to protect against them.
• UVA rays are longer, invisible rays that penetrate deeply into the skin, contributing to long-term damage and ageing – and they’re present even on cloudy days.

Our sunscreen has a silky-smooth texture designed to spread evenly across the skin. When warmed between the palms, it softens and glides on, leaving a fine silk-like residue. This residue is exactly what’s needed for consistent, effective UVB protection.
The product’s viscosity was a deliberate choice. We prioritised uniform SPF coverage and functional performance over a lighter, less protective feel.
