The Short Answer
If your sunscreen softens in summer or thickens in winter — that’s not a flaw.
That’s how real ingredients behave.
At Field + Forge, our Daily Mineral Defense is made with non-nano zinc oxide, plant oils, and natural waxes — never silicones, stabilizers, or lab-made emulsifiers. Because we keep it real, your sunscreen will respond to temperature like any natural product should.
☀️ Why Mineral Sunscreens React to Temperature
Unlike conventional sunscreens that use chemical UV filters and synthetic binders to “freeze” their texture in place, mineral formulas rely on nature’s chemistry.
Here’s what happens:
-
Warm temps: Plant oils and butters (like jojoba and mango butter) soften, making your sunscreen glide on effortlessly.
-
Cool temps: Waxes and butters naturally firm up, giving the product a thicker feel until it warms on your skin.
These shifts don’t affect protection — your SPF stays stable — they simply reflect how genuine, unprocessed ingredients behave without chemical manipulation.
🌬 How to Manage Texture Changes
Because our formula is free from synthetics and preservatives, a few small steps will help keep it in perfect condition:
In Cold Weather:
-
Warm the tin in your hands for 1–2 minutes before applying.
-
Store at room temperature (avoid freezing temps).
In Hot Weather:
-
Keep out of direct sunlight and avoid leaving it in your car.
-
If the top layer softens, pop it in a cool place for 10–15 minutes to reset.
If You Notice Separation:
-
Stir gently with a clean spatula or fingertip. Natural oils and waxes will blend right back together.
🌊 Why It’s Worth It
Choosing a true mineral sunscreen is a decision for your skin and the planet.
-
✅ Reef-safe: No oxybenzone, octinoxate, or microplastics.
-
✅ Skin-barrier friendly: Oils like jojoba and vitamin E nourish and repair while protecting.
-
✅ Non-toxic: Non-nano zinc oxide sits on the surface to reflect UV rays — not absorb them.
-
✅ Functional skincare: Breathable, restorative, and aligned with your skin’s natural rhythm.
🌾 The Takeaway
A little temperature sensitivity is the trade-off for a formula that’s clean, functional, and alive with real ingredients.
So the next time your tin softens in the sun or feels firm on a frosty morning, know that it’s just nature doing what it does best — keeping things real.
