As consumers become increasingly aware of the potential risks linked to chemical-based sunscreens, interest in natural sunscreen alternatives has surged. From zinc oxide to botanical oils, people are turning to non-toxic, eco-friendly sun protection to shield their skin without compromising their health—or the environment.
But how effective are natural sunscreens? What is the safest sunscreen to use? And what ingredients should you look for when searching terms like “safe sunscreen for sensitive skin” or “natural SPF ingredients”? Here’s a science-backed look at the best natural alternatives to traditional sunscreen.
Is Sunscreen Safe?
Overall, yes, sunscreen is safe when used as directed—and it's a crucial tool for protecting your skin against UV radiation, premature aging, and skin cancer. However, the type of sunscreen you use matters, and not all sunscreens are created equal.
Sunscreen is a topical product designed to protect the skin by either absorbing, reflecting, or scattering ultraviolet (UV) radiation from the sun. Sunscreens are typically categorized based on how they achieve this protection:
-
SPF (Sun Protection Factor) measures how well a sunscreen protects against UVB rays, the main cause of sunburn.
-
Broad-Spectrum Protection covers both UVA (aging rays) and UVB (burning rays).
-
Important Safety Notes:
-
Chemical sunscreens have been under scrutiny for potential systemic absorption and coral reef damage. Some ingredients like oxybenzone are banned in places like Hawaii.
-
Mineral sunscreens (especially those made with non-nano zinc oxide) are widely recognized as safer choices for both people and the environment.
-
Which Sunscreens Should You Avoid?
Many mainstream sunscreens use chemical UV filters like oxybenzone, avobenzone, and octinoxate. These ingredients have raised concerns due to:
-
Endocrine disruption: Some chemical filters can mimic hormones and interfere with normal function.
-
Skin irritation: Especially for those with sensitive skin or conditions like eczema.
-
Environmental harm: Chemicals like oxybenzone contribute to coral bleaching and marine ecosystem damage, prompting bans in places like Hawaii.
Natural Sunscreen Alternatives That Actually Work
1. Non-Nano Zinc Oxide
Zinc oxide is the gold standard in natural sun protection. It’s a broad-spectrum mineral filter that physically blocks UVA and UVB rays. Key features:
-
Non-nano particles stay on the skin’s surface rather than absorbing into the bloodstream.
-
Reef-safe and environmentally friendly.
-
Ideal for sensitive skin and babies.
Is Mineral Sunscreen Safe?
You may have heard zinc in sunscreen is bad; however, by choosing non-nano zinc oxide, the particles are large enough to provide broad-spectrum coverage without absorbing into the bloodstream.
✅ Found in: Eat My Face SPF 30 Beef Tallow Sunscreen
2. Titanium Dioxide
Another mineral sunscreen ingredient that reflects UV radiation. It’s often used in tandem with zinc oxide for fuller coverage, though it's slightly less effective at blocking UVA rays.
✅ Good for: Lightweight formulations for oily skin.
3. Plant-Based Oils with Low SPF
Some natural oils offer mild SPF protection, though they should never be used as a sole defense. Examples of natural sunscreen oil include:
-
Red Raspberry Seed Oil: Estimated SPF 25–40 (limited evidence)
-
Carrot Seed Oil: Popular in DIY recipes but lacks clinical backing
-
Coconut Oil: Offers SPF 4–5; mostly a moisturizer
⚠️ These should only supplement real SPF—not replace it. If you find yourself asking what can I use instead of sunscreen, try the effective minerals listed above.
4. Beef Tallow-Based Sunscreen
While not an SPF filter itself, grass-fed beef tallow serves as a nourishing base in natural sunscreens. It:
-
Enhances skin barrier function
-
Delivers fat-soluble vitamins A, D, E, and K
-
Is highly compatible with human skin lipids
✅ Pairs perfectly with non-nano zinc oxide for effective, edible-grade sun care.
🧴 Eat My Face Sunscreen blends tallow with zinc oxide, shea butter, and cocoa butter for a safe, soothing formula.

What to Avoid in "Natural" Products
Some products market themselves as “natural sunscreen” but include:
-
Fragrance: A common allergen that can increase sun sensitivity
-
Essential oils in high concentrations: Like citrus oils, which may make your skin more prone to sunburn
-
Micronized/nano particles: These can penetrate skin or harm aquatic life
Always read the label and opt for transparent, ingredient-first brands to ensure you are getting what's the safest sunscreen to use.
FAQs:
-
Is sunscreen good?
- Yes! Sunscreen is a crucial tool for protecting your skin against UV radiation, premature aging, and skin cancer.
-
What sunscreens are safe? What is the safest sunscreen?
- The safest sunscreens are mineral sunscreens that use non-nano zinc oxide or titanium dioxide as active ingredients. They sit on top of the skin to physically block UV rays without being absorbed into the body. Look for formulas that are broad-spectrum, reef-safe, and free from harmful chemicals like oxybenzone and octinoxate.
-
Does cheap sunscreen work?
- Yes - but it depends. The effectiveness of sunscreen is based on the active ingredients and SPF rating. If a cheap sunscreen lists effective UV filters, it technically works. However, you will most likely get lower quality inactive ingredients that can cause irritation and clogged pores. Cheap formulas may be sticky, heavy, or leave a strong white cast. Cheaper brands may skimp on stability or rely on chemical filters. If you're looking for what is the safest sunscreen for your face, you'll want to choose high quality ingredients that are non-comedogenic (like our SPF 30 Beef Tallow Sunscreen).
-
Are chemical sunscreens more effective than mineral?
- Chemical and mineral sunscreens are both effective when properly formulated, but they work differently—chemical sunscreens absorb UV rays, while mineral sunscreens reflect them. Some chemical filters may offer slightly higher UVA protection, but they come with potential health and environmental concerns. Mineral sunscreens with non-nano zinc oxide provide excellent broad-spectrum protection and are a safer choice for sensitive skin and reef safety.
-
How is sunscreen evaluated?
- Sunscreen is evaluated by measuring its Sun Protection Factor (SPF), which tests how well it protects against UVB rays, the main cause of sunburn. Products must also undergo broad-spectrum testing to prove they shield against both UVA and UVB radiation. Stability, water resistance, and safety are also assessed under controlled laboratory conditions before a sunscreen can be marketed.
Final Thoughts
If you’re searching for which sunscreen is safe, chemical-free sunscreen, reef-safe SPF, or natural sunblock that actually works, the answer lies in mineral-based formulations, especially those using non-nano zinc oxide. When combined with nourishing ingredients like beef tallow, you get sun protection that’s not just safe—it’s skin food.
