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.
Tocopheryl acetate is a stable, esterified form of vitamin E used in skincare as an antioxidant and conditioning agent. It is converted to active tocopherol in the skin, helping protect against oxidative stress and supporting the skin barrier.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness | Uncommon | Its volatility can contribute to a dry or tight feeling on the skin with frequent use. |
| Irritation | Rare | Mild irritation or stinging may occur, particularly on sensitive or compromised skin. |
| Allergic contact dermatitis | Very rare | Sensitization is uncommon as it is generally considered non-sensitizing. |
| Eye irritation | Rare | Can cause transient stinging if it migrates into the eyes in eye-area products. |
| Skin irritation | Rare | Generally well tolerated; mild irritation possible in sensitive individuals. |
| Contact dermatitis / allergic reaction | Very rare | Allergic sensitization is uncommon for this inert hydrocarbon. |
| Comedogenicity / clogged pores | Very rare | Considered low comedogenic, but heavy occlusive use may contribute in acne-prone skin. |
| Acne/comedogenicity | Rare | Typically regarded as low or non-comedogenic, though some individuals report congestion with heavy silicone use. |
| White cast / cosmetic residue on skin | Common | Non-micronized particles can leave a visible white film, especially on darker skin tones. |
| Dryness or mild skin tightness | Uncommon | Due to its astringent nature, particularly in high concentrations. |
| Clogged pores / acne aggravation | Uncommon | More often attributed to occlusive base ingredients than to zinc oxide itself. |
| Contact irritation or stinging | Rare | Generally well tolerated; irritation often relates to other formulation components. |
| Mild skin irritation | Rare | Generally well tolerated; occasional transient irritation reported in sensitive individuals. |
| Contact allergy / sensitization | Very rare | Rarely implicated in allergic contact dermatitis; considered low sensitizing potential. |
| Comedogenicity / pore congestion | Rare | Low comedogenic rating, but acne-prone individuals may occasionally experience clogged pores. |

| Ingredient | What it does |
|---|---|
| Isododecane Emollient/solvent | Isododecane is a lightweight, volatile branched-chain hydrocarbon used as a solvent and emollient in cosmetics. It spreads easily and evaporates quickly, improving texture and wear in products like long-lasting makeup, primers, and sunscreens. |
| C13-15 Alkane Emollient / solvent | C13-15 Alkane is a lightweight, plant-derived (often sugarcane-based) liquid hydrocarbon used as an emollient and spreading agent in skincare. It softens skin, improves product texture, and serves as a sustainable alternative to silicones and mineral oil. |
| Dimethicone/Vinyl Dimethicone Crosspolymer Silicone elastomer / texture enhancer | Dimethicone Vinyl Dimethicone Crosspolymer is a crosslinked silicone elastomer used in skincare and cosmetics to impart a silky, smooth feel, absorb excess oil, blur the appearance of pores and fine lines, and improve product spreadability. It functions as a formulation/sensory agent rather than a biologically active treatment ingredient. |
| 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. |
| Coco-Caprylate/Caprate Emollient / skin-conditioning agent | Coco-Caprylate/Caprate is a lightweight ester emollient derived from coconut-sourced fatty alcohols and caprylic/capric acids, used to provide a smooth, dry, non-greasy skin feel and to act as a silicone alternative. It functions primarily as a spreading agent and texture enhancer in lotions, creams, and sunscreens. |
| Polyglyceryl-3 Polyricinoleate Emulsifier | Polyglyceryl-3 Polyricinoleate (PGPR) is a polyglycerol ester of polyricinoleic acid (derived from castor oil) used as a lipophilic emulsifier and stabilizer, primarily in water-in-oil emulsions and lip/color cosmetics. It helps reduce viscosity and stabilize oil-based formulations. |
| Isostearic Acid Emollient/emulsifier | Isostearic acid is a branched-chain fatty acid used in cosmetic formulations as an emollient, co-emulsifier, and dispersing agent that improves spreadability and texture. It is valued for its oxidative stability and liquid consistency compared to straight-chain stearic acid. |
| 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. |
| Tocopheryl Acetate Key active Antioxidant | Tocopheryl acetate is a stable, esterified form of vitamin E used in skincare as an antioxidant and conditioning agent. It is converted to active tocopherol in the skin, helping protect against oxidative stress and supporting the skin barrier. |
| Phenoxyethanol Preservative | Phenoxyethanol is a widely used broad-spectrum preservative that protects cosmetic and skincare formulations from bacterial and fungal contamination. It is typically used at concentrations up to 1% and serves as a formulation/base ingredient rather than an active treatment. |
