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.
Vitamin E (tocopherol) is a fat-soluble antioxidant used in skincare to protect cells from oxidative damage and to stabilize formulations against rancidity. It also functions as an emollient and helps support the skin barrier.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Uncommon | Localized redness, itching, or rash in sensitized individuals. |
| Mild stinging or burning on application | Uncommon | More likely on broken or highly sensitive skin. |
| Contact urticaria (hives) | Rare | Immediate hypersensitivity reaction reported in isolated cases. |
| Delayed wound healing with prolonged use | Very rare | Reported in some studies on surgical or chronic wounds. |
| Skin irritation | Rare | Generally well tolerated; mild irritation possible in sensitive individuals. |
| Comedogenicity / breakouts | Uncommon | Low comedogenic potential but may contribute to clogged pores in acne-prone skin. |
| Contact urticaria | Very rare | Isolated reports of hive-like reactions tied to benzoate moiety. |
| Sticky or tacky skin feel | Common | Cosmetic sensation at higher concentrations, not a health concern. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or with high concentrations. |
| Skin dryness or moisture-wicking in very low humidity | Uncommon | Can theoretically draw water from skin in extremely dry environments if not paired with occlusives. |
| Mild skin irritation or stinging | Uncommon | Usually transient, more likely on compromised or sensitive skin or at high concentrations. |
| Eye irritation | Uncommon | Can occur with direct contact in eye-area products. |
| Mild skin irritation | Uncommon | Transient stinging or redness, more likely on compromised or sensitive skin. |
| Enhanced penetration of co-formulated irritants | Uncommon | As a penetration enhancer it may increase absorption and irritation potential of other actives. |

| Ingredient | What it does |
|---|---|
| Aloe Vera Leaf Ext Soothing/hydrating agent | Aloe vera leaf extract is a plant-derived ingredient used in skincare for its moisturizing, soothing, and mild anti-inflammatory properties. It is commonly added to formulations to calm irritation and support skin hydration. |
| 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. |
| Glycerine Humectant | Glycerine (glycerol) is a humectant that draws water into the stratum corneum and helps maintain skin hydration and barrier function. It is widely used as a base/formulation ingredient in moisturizers, cleansers, and serums. |
| 3-Butylene Glycol Humectant/solvent | 3-Butylene glycol (butylene glycol) is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent. It helps attract moisture, dissolve other ingredients, and improve product texture and preservation. |
| Propanediol Humectant/solvent | Propanediol is a plant-derived glycol used in skincare as a humectant, solvent, and penetration enhancer that improves moisturization and the spreadability of formulations. It also helps solubilize other ingredients and can boost the efficacy of certain actives. |
| 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. |
| Sodium Hyaluronate Humectant / hydrator | Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan that attracts and binds water to the skin to improve hydration and surface plumpness. Its lower molecular weight allows better penetration than native hyaluronic acid. |
| Benzyl Alcohol (And) Ethylhexylglycerin (And) Tocopherol Preservative blend / antioxidant | A multifunctional formulation blend combining benzyl alcohol and ethylhexylglycerin as preservatives/skin-conditioning agents with tocopherol (vitamin E) as an antioxidant. It is used to protect products from microbial spoilage and oxidation rather than to treat skin conditions. |
| Polysorbate 20 Emulsifier / solubilizer | Polysorbate 20 is a nonionic surfactant derived from sorbitol and lauric acid, used in skincare to solubilize fragrances and essential oils and to stabilize oil-in-water emulsions. It functions primarily as a formulation aid rather than a treatment active. |
| Bamboo Water Hydrating base/solvent | Bamboo water is the liquid extracted from bamboo (often Bambusa vulgaris), used as a water-replacement base in skincare for its silica, mineral, and antioxidant content. It primarily serves as a hydrating, soothing vehicle rather than a high-potency active ingredient. |
| Ammonium Acryloyldimethyltaurate/Vp Copolymer Thickener/stabilizer | Ammonium Acryloyldimethyltaurate/VP Copolymer is a synthetic acrylic copolymer used in skincare to thicken, gel, and stabilize emulsions, providing viscosity control and a smooth texture. It functions as a rheology modifier and film former rather than a biologically active treatment ingredient. |
| Sodium Gluconate Chelating agent / skin-conditioning | Sodium gluconate is the sodium salt of gluconic acid used in skincare primarily as a chelating agent to bind metal ions and stabilize formulations, with secondary humectant and skin-conditioning properties. It is generally considered a base/formulation ingredient rather than an active treatment. |
| Vitamin E Key active Antioxidant / emollient | Vitamin E (tocopherol) is a fat-soluble antioxidant used in skincare to protect cells from oxidative damage and to stabilize formulations against rancidity. It also functions as an emollient and helps support the skin barrier. |
