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.
Diethylamino Hydroxybenzoyl Hexyl Benzoate (also known as Uvinul A Plus) is an oil-soluble organic UV filter that absorbs primarily in the long-wave UVA range (around 354 nm), helping protect skin from UVA-induced damage. It is photostable and commonly combined with other filters in broad-spectrum sunscreens.

It is a film-forming polymer that helps stabilize and enhance the efficacy of other UV filters.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
Ethylhexyl Triazone is an oil-soluble organic UV filter that strongly absorbs UVB radiation (peak around 314 nm), valued for its high photostability and efficiency at low concentrations. It is commonly used in sunscreens and daily-wear products to boost SPF.
Adenosine is a nucleoside that signals through cell-surface receptors to promote dermal fibroblast activity and collagen/elastin production, helping reduce the appearance of fine lines and wrinkles. It also has anti-inflammatory and soothing properties at low concentrations commonly used in cosmetics (around 0.04-0.1%).
Aggregated from the active ingredients in this product.

| 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. |
