What’s Actually in Your Sunscreen?

Why More People Are Switching to Mineral Zinc Protection

When most people shop for sunscreen, they look at the SPF number first.

But what’s inside the formula matters just as much.

Many conventional sunscreens rely on chemical UV filters designed to absorb into the skin and convert UV rays into heat. Mineral sunscreens work differently. Instead of absorbing UV rays, zinc oxide creates a physical barrier that reflects them away from the skin.

At Summer Solace Tallow, we believe sun care should feel simple, nourishing, and transparent. That’s why our zinc balms are crafted with 23% non-nano, uncoated Zinc Oxide USP paired with regenerative tallow and whole-food ingredients that support the skin barrier while protecting it.

What Is Zinc Oxide?

Zinc Oxide USP is a naturally occurring mineral commonly used in mineral sunscreens, diaper creams, and soothing skin balms.

Unlike chemical sunscreen filters, zinc oxide sits on the surface of the skin instead of being absorbed into it. It works by physically reflecting both UVA and UVB rays, providing broad-spectrum sun protection.

Mineral zinc protection is often preferred by people with:

• Sensitive skin
• Reactive or allergy-prone skin
• Fragrance sensitivities
• Children or babies
• Concerns about overly complicated skincare ingredients

What Does “Zinc Oxide USP” Mean?

“USP” stands for United States Pharmacopeia, a recognized benchmark for ingredient quality and purity.

When a formula contains Zinc Oxide USP, it means the ingredient has been tested to meet strict standards for:

• Purity
• Identity
• Quality
• Contaminants
• Suitability for topical skin application

In simple terms: it’s a higher-quality grade of zinc oxide commonly used in skincare and pharmaceutical applications.

Mineral Sunscreen vs Chemical Sunscreen

Chemical Sunscreens

Chemical sunscreen formulas work by absorbing UV rays and converting them into heat within the skin.

These formulas often contain ingredients such as:

• Oxybenzone
• Octinoxate
• Avobenzone
• Octocrylene

Chemical sunscreens are popular because they can feel lightweight and blend invisibly into the skin. However, some people prefer to avoid them due to skin sensitivity or ingredient concerns.

Mineral Sunscreens

Mineral sunscreen formulas use ingredients like zinc oxide to create a physical shield on the skin.

Benefits of mineral zinc protection include:

• Broad-spectrum UVA and UVB coverage
• Works immediately upon application
• Sits on the skin instead of absorbing into it
• Gentle for sensitive skin
• Reef-safe and environmentally conscious
• Often less irritating for reactive skin types

Why Non-Nano Zinc Matters

Not all zinc oxide is the same.

Our formulas use non-nano, uncoated zinc oxide, meaning the particles are intentionally larger and remain on the skin’s surface rather than being designed for deeper penetration.

This approach supports:

• Gentle mineral protection
• Better skin compatibility
• Reef-safe sun care
• A more traditional approach to sunscreen formulation

Why We Pair Zinc with Regenerative Tallow

Sun protection should not leave your skin feeling dry or stripped.

That’s why our zinc balms combine mineral protection with regenerative suet tallow sourced from Northern California cattle. Tallow is naturally rich in:

• Vitamins A, D, E, and K
• Fatty acids that support the skin barrier
• Deeply nourishing lipids similar to the skin’s own oils

We also blend:

• Organic calendula CO₂ extract
• Séka Hills extra-virgin olive oil
• Organic jojoba oil
• Raw local beeswax
• Botanical oils and pearl extract

The result is a formula that protects while actively supporting healthy, nourished skin.
