Octyl Methoxycinnamate (Octinoxate) is a widely used organic UVB filter that absorbs ultraviolet radiation to protect skin from sunburn and photodamage. It is commonly incorporated into sunscreens and daily-care products with SPF claims.
Zinc oxide is a mineral (inorganic) UV filter that provides broad-spectrum protection against UVA and UVB radiation by scattering and absorbing light. It also has mild astringent and soothing properties and is used in sunscreens, diaper creams, and barrier preparations.
Diethylhexyl Butamido Triazone (Iscotrizinol, Uvasorb HEB) is an organic, oil-soluble UVB filter that absorbs ultraviolet radiation primarily in the UVB range, providing photoprotection in sunscreen and daily-care formulations. It is highly photostable and substantive to skin, often combined with other filters for broad-spectrum coverage.
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.
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%.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Rare | Generally considered non-irritating; occasional mild reactions reported. |
| Contact allergy/sensitization | Very rare | Silicones are low-allergenicity; documented allergic reactions are exceptional. |
| Eye irritation | Rare | Possible transient stinging if product enters the eyes. |
| Mild skin irritation or redness | Rare | Generally considered non-irritating; occasional mild reactions reported. |
| Clogged pores / comedogenic-related breakouts | Uncommon | Often anecdotal; dimethicone is largely regarded as non-comedogenic but may trap debris if skin is not cleansed well. |
| Allergic contact dermatitis | Very rare | True silicone allergy is exceptionally uncommon. |
| Eye irritation on accidental contact | Rare | Transient stinging or discomfort if product enters the eyes. |
| Mild transient skin irritation | Rare | Generally considered well tolerated; irritation is uncommon and usually mild. |
| Contact allergy / allergic contact dermatitis | Very rare | Silicone elastomers have very low sensitization potential; reports are exceedingly uncommon. |
| Pore congestion or comedogenic feel | Rare | Largely non-comedogenic, but occlusive film may trap debris in occlusion-prone or acne-prone users. |
| Contact irritation | Uncommon | Mild stinging or redness, especially on sensitive or compromised skin. |
| Photoallergic/photocontact dermatitis | Rare | Reaction triggered by combined exposure to the ingredient and sunlight. |
| Potential endocrine activity | Very rare | Weak estrogenic effects observed in laboratory and animal studies; clinical relevance at typical use levels is uncertain. |
| Contact allergy / sensitization | Very rare | Silicones are considered low-allergenic; documented reactions are exceptional. |
| Acne or comedone formation | Rare | Generally regarded as non-comedogenic, but isolated breakouts may occur depending on formulation. |

| Ingredient | What it does |
|---|---|
| Cyclopentasiloxane Emollient/silicone | Cyclopentasiloxane is a volatile cyclic silicone widely used in skincare and cosmetics to impart a smooth, silky feel and spreadability before evaporating, leaving no greasy residue. It also serves as a carrier and helps reduce tackiness in formulations. |
| Dimethicone Emollient/occlusive (silicone) | Dimethicone is a silicone-based polymer used in skincare to soften skin, smooth texture, and form a breathable protective barrier that reduces transepidermal water loss. It is widely used as a base/formulation ingredient rather than a therapeutic active. |
| Vinyl Dimethicone Crosspolymer Silicone-based film former / texture enhancer | Vinyl Dimethicone Crosspolymer is a crosslinked silicone elastomer used in skincare and cosmetics to impart a smooth, silky feel, blur pores and fine lines, and provide a soft-focus, non-greasy finish. It functions primarily as a sensory and film-forming agent rather than a biologically active treatment ingredient. |
| Octyl Methoxycinnamate Key active UV filter (sunscreen) | Octyl Methoxycinnamate (Octinoxate) is a widely used organic UVB filter that absorbs ultraviolet radiation to protect skin from sunburn and photodamage. It is commonly incorporated into sunscreens and daily-care products with SPF claims. |
| Caprylyl Methicone Emollient / spreading agent | Caprylyl Methicone is a volatile silicone fluid used in cosmetic formulations to provide a light, non-greasy, smooth skin feel and to enhance the spreadability of products. It also acts as a solvent and carrier for other ingredients, particularly in sunscreens and color cosmetics. |
| PEG-12 Dimethicone/PPG-20 Crosspolymer Silicone emulsifier/conditioning agent | PEG-12 Dimethicone/PPG-20 Crosspolymer is a silicone-based crosspolymer used in cosmetic formulations primarily as an emulsifier, emollient, and skin-conditioning agent. It helps stabilize emulsions and impart a smooth, silky feel to products. |
| C12-15 Alkyl Benzoate Emollient / texture enhancer | C12-15 Alkyl Benzoate is a lightweight ester emollient widely used in skincare and cosmetics to improve spreadability, provide a smooth non-greasy skin feel, and act as a solvent and mild antimicrobial booster. It is considered a base/formulation ingredient rather than a treatment active. |
| Zinc Oxide Key active UV filter / skin protectant | Zinc oxide is a mineral (inorganic) UV filter that provides broad-spectrum protection against UVA and UVB radiation by scattering and absorbing light. It also has mild astringent and soothing properties and is used in sunscreens, diaper creams, and barrier preparations. |
| Triethoxycaprylylsilane Coating/surface treatment agent | Triethoxycaprylylsilane is a silane-based ingredient primarily used to coat and hydrophobically treat powders and pigments such as titanium dioxide, zinc oxide, and iron oxides, improving their dispersion, water resistance, and texture in cosmetic formulations. It functions as a formulation aid rather than a skin-treatment active. |
| Diethylhexyl Butamido Triazone Key active UVB filter (sunscreen agent) | Diethylhexyl Butamido Triazone (Iscotrizinol, Uvasorb HEB) is an organic, oil-soluble UVB filter that absorbs ultraviolet radiation primarily in the UVB range, providing photoprotection in sunscreen and daily-care formulations. It is highly photostable and substantive to skin, often combined with other filters for broad-spectrum coverage. |
| Diethylamino Hydroxybenzoyl Hexyl Benzoate Key active UVA filter (sunscreen) | 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. |
| Niacinamide Key active Cell-communicating / barrier-repair active | 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%. |
| Tapioca Starch Absorbent / texture enhancer | Tapioca starch is a plant-derived polysaccharide powder used in cosmetics to absorb excess oil and moisture, impart a soft matte finish, and improve the sensory texture of formulations. It functions as a base/formulation ingredient rather than a therapeutic active. |
| Polymethylsilsesquioxane Texture enhancer / mattifying agent | Polymethylsilsesquioxane is a silicone-based spherical powder used in skincare and cosmetics to impart a smooth, soft-focus, mattifying feel and improve spreadability. It is a formulation/texture ingredient rather than a treatment active. |
