Niacinamide is a form of vitamin B3 used in skincare to support the skin barrier, reduce transepidermal water loss, even skin tone, and regulate sebum. It is generally well tolerated across a wide range of skin types.
Ethylhexyl Methoxycinnamate (octinoxate) is a widely used organic UVB-absorbing sunscreen agent that protects skin from ultraviolet radiation. It is commonly incorporated into sunscreens and daily cosmetics with SPF claims.
Titanium dioxide is an inorganic mineral compound used primarily as a physical (mineral) sunscreen agent that reflects and scatters UV radiation, and also serves as a white pigment and opacifier in cosmetic formulations. It is broadly photostable and considered gentle, making it common in products for sensitive and pediatric skin.
Drometrizole Trisiloxane (Mexoryl XL) is a broad-spectrum, photostable organic UV filter that absorbs both UVA and UVB radiation, used in sunscreens to provide photoprotection. Its silicone-based structure gives it oil solubility and substantivity on skin.
Terephthalylidene Dicamphor Sulfonic Acid (also known as ecamsule or Mexoryl SX) is a water-soluble organic UVA filter used in sunscreens to provide broad protection against UVA rays. It is photostable and often combined with other filters to enhance coverage.
Tocopherol (vitamin E) is a lipid-soluble antioxidant used in skincare to protect skin and formulations from oxidative damage caused by free radicals and UV exposure. It also functions as a skin-conditioning and emollient agent and can stabilize oils against rancidity.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient tingling or warmth on application | Uncommon | Usually brief and self-resolving, more likely at higher concentrations. |
| Facial flushing or redness | Rare | Topical niacinamide rarely causes the flushing associated with oral niacin; more likely if formulation contains niacin impurities. |
| Mild irritation, dryness, or stinging | Uncommon | More common at concentrations above 5% or in sensitive/compromised skin. |
| Allergic contact dermatitis | Very rare | Isolated case reports; patch testing can confirm sensitivity. |
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Contact irritation or mild stinging | Uncommon | Transient skin irritation, especially on sensitive or compromised skin. |
| Photoallergic contact dermatitis | Rare | Reaction triggered by combined exposure to the ingredient and sunlight. |
| Potential endocrine/estrogenic activity | Very rare | Suggested by in vitro and animal studies; human relevance at cosmetic exposure levels remains uncertain. |
| White cast on skin | Common | Cosmetic effect, more pronounced on deeper skin tones and with non-micronized grades. |
| Skin dryness or mild irritation | Uncommon | Usually related to the overall formulation rather than the ingredient itself. |
| Contact dermatitis or allergic reaction | Rare | Titanium dioxide is a recognized low-sensitizing ingredient; reactions are infrequent. |
| Comedogenicity / clogged pores | Rare | Can occur in some individuals depending on coating and formulation base. |
| Inhalation-related respiratory concern | Very rare | Relevant only to loose powder/spray forms via inhalation, not topical leave-on use. |
