Rice water & Niacinamide Hybrid Sunscreen — ingredient safety report

• Allergy risk:The most common cause of sunscreen photoallergy.
• Environmental impact:Linked to coral bleaching; banned in Hawaii and other reef regions.

The most controversial chemical UV filter: a top cause of sunscreen allergy, a suspected endocrine disruptor found in blood and breast milk, and banned in several reef jurisdictions for coral toxicity.

• Environmental impact:Toxic to coral; banned in Hawaii alongside oxybenzone.

A UVB filter under regulatory re-review for hormonal effects and banned in some reef regions; steadily being replaced by newer filters in modern sunscreens.

• Allergy risk:Degradation products can cause photoallergy when unstabilized.

The main UVA filter in US sunscreens. Safe when properly stabilized, but it breaks down in sunlight into potentially sensitizing fragments in poorly formulated products.

• Allergy risk:One of the 26 EU-declarable fragrance allergens.
• Irritation:Mild irritation possible at higher concentrations.

A preservative and fragrance component that must be declared on EU labels because it can trigger contact allergy in a small share of users.

• Cancer concern:IARC 2B by inhalation only — relevant to loose powders and sprays, not creams.

A mineral UV filter and pigment that is one of the safest sunscreen choices in cream form; the inhalation-based cancer classification only matters for powder and spray formats.

• Irritation:Occasional transient stinging or redness on sensitive skin.

A mild food-grade preservative usually paired with sodium benzoate; well tolerated by most skin types.

• Irritation:Can cause transient, non-allergic flushing/stinging on reactive skin.

A food-grade preservative generally regarded as one of the gentler options; occasional non-immune stinging is its main drawback.
