What Daily Sun Serum SPF 30 Mineral Sunscreen is made of, ingredients and materials
Daily Sun Serum SPF 30 is a mineral sunscreen formulated with zinc oxide as the active UV filter, which works by reflecting and scattering UV radiation on the skin surface rather than absorbing it chemically. Zinc oxide is a non-systemic ingredient with a long safety history in topical products. The mineral base avoids synthetic organic UV absorbers (like oxybenzone or avobenzone) that carry different toxicological profiles. No coatings, nanoparticle specifications, or proprietary surface treatments are named in available product information for this formulation.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
1,4-dioxane (non-intentional contaminant from surfactants/emulsifiers)
Mineral sunscreen serums typically include emulsifiers or solubilizers to suspend zinc oxide; these ingredients may carry trace 1,4-dioxane if not purified during manufacture. Derma E's clean-beauty positioning suggests attention to supplier quality, but trace contamination is possible in any cosmetic product and is not specific to this brand or product on public record.
Fragrance allergens (if fragrance is present)
Product name and marketing do not confirm fragrance-free status; if the formulation includes fragrance compounds (essential oils, synthetic fragrance), components such as limonene, geraniol, or linalool may trigger contact dermatitis in sensitive individuals. Check full ingredient list for fragrance disclosure.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Third-party PFAS-free verification
A third party reports verifying this product as PFAS-free.
No PFAS found in lab test
No PFAS detected in independent testing.
Formaldehyde / VOCs
No formaldehyde-releasing preservatives (DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea) are disclosed in available product ingredient lists or brand documentation for this product.
Source, ATSDR ↗Heavy metals
Zinc oxide itself is the active ingredient and is not a source of lead, cadmium, or arsenic at cosmetic concentrations. No iron oxides, chromium compounds, or synthetic colorants known to concentrate heavy metals are named in this formulation.
Source, FDA ↗Talc contamination
Mineral sunscreens formulated with zinc oxide alone do not inherently contain talc. No asbestos-linked talc or powder carriers are named in available product descriptions for this serum formulation.
How is this PFAS grade calculated?
The brand's record and disclosure
Derma E is a dermatology-focused personal care brand with third-party PFAS-free verification on this product, indicating independent testing and disclosure commitment. The brand has established marketing around clean ingredient practices and has not faced major product recalls or safety controversies on record in public databases. Transparency on ingredient sourcing and third-party certifications supports consumer confidence, though as with any cosmetic brand, individual users may experience sensitivity to non-active ingredients (emollients, preservatives, fragrance compounds).
How it compares in its category
Mineral sunscreens occupy a distinct safety niche compared to chemical sunscreens, as they do not rely on systemic absorption or endocrine-active filters. Within mineral sunscreen products, zinc oxide-only formulations carry lower complexity than titanium dioxide blends or those with added nanoparticle claims. This product's third-party PFAS verification is a stronger disclosure posture than many mass-market sunscreens, where PFAS testing is less common or transparent. Price point and sensory profile (thickness, white cast) are typical trade-offs for mineral formulations but do not reflect safety differences.
If you buy it
Apply liberally (about one quarter teaspoon for face) and reapply every 2 hours or after water exposure; mineral sunscreens do not degrade significantly from normal body heat or indoor use. Store in a cool, dry place away from direct sunlight to prevent carrier oil or emollient degradation over time. Discard and replace if the product separates, discolors, or shows visible mold growth, which can occur if water is introduced (e.g., in a humid bathroom without proper sealing). Discontinue use and consult a dermatologist if redness, itching, or burning develops; zinc oxide is rare as a sensitizer but fragrance or preservatives in the formulation may trigger individual reactions.
