Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or sensitivity | Very rare | Purified water is essentially inert; reactions are attributable to other formula components, not the water itself. |
| Transient skin barrier disruption from excessive exposure | Rare | Prolonged or repeated wetting can contribute to mild barrier compromise, but this relates to usage patterns rather than the ingredient. |
| Mild skin irritation or stinging | Common | More likely at higher concentrations or on compromised/sensitive skin |
| Allergic contact dermatitis | Uncommon | Recognized contact allergen; confirmed via patch testing |
| Irritant contact dermatitis | Uncommon | Non-allergic irritation, often dose-dependent |
| Worsening of pre-existing eczema or barrier-impaired skin | Rare | Penetration-enhancing effect may increase reactivity |
| Systemic toxicity from topical use | Very rare | Reported mainly with extensive application on broken skin, especially in infants or burn patients |
| Mild irritation or stinging | Rare | Generally considered non-irritating; occasional reports in sensitive individuals. |
| Contact dermatitis / allergic reaction | Very rare | Allergic sensitization to this purified hydrocarbon is uncommon. |
| Comedogenicity / clogged pores | Rare | Typically rated low-comedogenic, but heavy occlusive use may contribute to congestion in acne-prone skin. |
| Mild skin irritation | Rare | Occasional transient redness or stinging, typically in sensitive skin. |
| Contact dermatitis | Very rare | Isolated allergic or irritant reactions reported; generally considered low-sensitizing. |
| Eye irritation | Rare | May cause mild irritation on direct eye contact during application. |
| Contact dermatitis or allergic sensitization | Rare | Reported occasionally with ethoxylated surfactants. |
| Concern over 1,4-dioxane trace contamination | Rare | Byproduct of ethoxylation; minimized by purification during manufacturing. |

| Ingredient | What it does |
|---|---|
| Purified Water Solvent/vehicle | Purified water is a highly filtered, deionized water used as the primary solvent and base in most skincare formulations. It dissolves water-soluble ingredients and provides the medium in which other components are dispersed. |
| Propylene Glycol Humectant / solvent | Propylene glycol is a small glycol molecule widely used in skincare as a humectant, solvent, and penetration enhancer that helps attract water and dissolve other ingredients. It is considered a base/formulation ingredient rather than a therapeutic active. |
| Hydrogenated Polydecene Emollient / skin-conditioning agent | Hydrogenated Polydecene is a synthetic hydrocarbon emollient derived from hydrogenated polydecene oligomers, used to provide a lightweight, non-greasy occlusive film that softens skin and improves spreadability in cosmetic formulations. It serves as a base or texture-enhancing ingredient rather than a biologically active treatment. |
| Sodium Polyacryloyldimethyl Taurate Emulsifier / thickener | Sodium Polyacryloyldimethyl Taurate is a synthetic acrylate-based polymer used as a thickening, stabilizing, and emulsifying agent in cosmetic formulations. It helps create smooth, gel-like textures and stabilizes oil-in-water emulsions. |
| Trideceth-10 Surfactant/emulsifier | Trideceth-10 is a polyethylene glycol ether of tridecyl alcohol used as a nonionic surfactant, emulsifier, and solubilizer in cosmetic formulations. It helps blend oil and water phases and stabilize emulsions rather than providing a direct skin treatment effect. |
| Glycerin Humectant | Glycerin is a widely used humectant that attracts and retains water in the skin, helping to hydrate the stratum corneum and support barrier function. It is considered safe and well-tolerated across most skin types and concentrations. |
| Benzoyl Peroxide Key active Acne treatment / antibacterial | Benzoyl peroxide is a topical antimicrobial and keratolytic agent widely used to treat acne by reducing Cutibacterium acnes bacteria and promoting follicular exfoliation.
