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%.
Zinc PCA is the zinc salt of pyrrolidone carboxylic acid used in skincare to help control excess sebum, support antimicrobial activity, and provide mild hydration. It is commonly included in products targeting oily and acne-prone skin.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| Mild transient flushing or redness | Uncommon | More likely at higher concentrations or in sensitive skin; usually subsides quickly. |
| Tingling, stinging, or burning sensation | Uncommon | Often associated with higher percentages or compromised barrier. |
| Contact irritation or itching | Rare | Generally dose-dependent and resolves with discontinuation. |
| Allergic contact dermatitis | Very rare | Documented in isolated case reports; true sensitization is unusual. |
| Mild skin irritation | Rare | Occasional transient redness or stinging, typically at higher concentrations or on compromised skin. |
| Enhanced irritation from co-formulated actives | Uncommon | By increasing penetration, it may intensify the effects or irritation potential of other ingredients. |
| Eye irritation | Rare | Can occur with accidental contact in concentrated form. |
| Mild transient stinging or irritation | Uncommon | More likely at high concentrations or on compromised/broken skin. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
| Mild skin irritation or stinging | Uncommon | Usually transient, more likely on sensitive or compromised skin. |
| Redness (erythema) | Uncommon | Typically mild and temporary at application site. |
| Dryness or skin tightness | Rare | May occur with overuse due to sebum-reducing effect. |

| Ingredient | What it does |
|---|---|
| Aqua Solvent / vehicle | Aqua (water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble components and forms the medium for emulsions. It has no direct treatment activity and primarily contributes to texture, spreadability, and product delivery. |
| 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%. |
| 1,3-Propanediol Humectant/solvent | 1,3-Propanediol is a naturally derived (often corn-based) humectant and solvent used in cosmetics to hydrate skin, enhance ingredient penetration, and improve product texture. It is widely considered a gentle, well-tolerated formulation ingredient. |
| Ethoxydiglycol Solvent / penetration enhancer | Ethoxydiglycol (diethylene glycol monoethyl ether) is a glycol ether used in cosmetic formulations primarily as a solvent and viscosity reducer that helps dissolve active ingredients and improve their skin penetration. It is considered a formulation aid rather than a therapeutic active. |
| 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. |
| Zinc Pca Key active Sebum-regulating, antimicrobial | Zinc PCA is the zinc salt of pyrrolidone carboxylic acid used in skincare to help control excess sebum, support antimicrobial activity, and provide mild hydration. It is commonly included in products targeting oily and acne-prone skin. |
| Dimethyl Isosorbide Solvent / penetration enhancer | Dimethyl Isosorbide (DMI) is a small, polar solvent derived from isosorbide used in cosmetic formulations to dissolve active ingredients and enhance their penetration into the skin. It functions as a vehicle and carrier rather than a therapeutic active itself. |
| Pentylene Glycol Humectant / solvent / preservative-booster | Pentylene glycol is a glycol used in cosmetics as a humectant and solvent that also enhances the antimicrobial efficacy of formulations, helping reduce reliance on traditional preservatives. It improves skin hydration and aids the delivery and stability of other ingredients. |
| Xanthan Gum Thickener/stabilizer | Xanthan gum is a polysaccharide produced by bacterial fermentation, used in skincare as a thickening, gelling, and emulsion-stabilizing agent. It improves product texture and suspension of ingredients without contributing active treatment effects. |
| Hydroxyethyl Cellulose Thickener / viscosity modifier | Hydroxyethyl cellulose is a non-ionic, water-soluble cellulose derivative used to thicken and stabilize aqueous skincare formulations and improve texture. It functions as a rheology modifier and film-forming agent rather than a biologically active treatment ingredient. |
| Algin Thickener/film-former | Algin (sodium alginate) is a polysaccharide derived from brown seaweed used in skincare as a thickening, gelling, and film-forming agent. It helps stabilize emulsions and provides a hydrating, smooth texture, commonly featured in peel-off masks. |
| 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. |
| Sodium Benzoate Preservative | Sodium benzoate is a salt of benzoic acid used as a preservative in cosmetic and skincare formulations to inhibit the growth of bacteria, yeast, and fungi, particularly in acidic products. It is most effective at a pH below 5. |
| Ethylhexylglycerin Preservative booster / skin-conditioning agent | Ethylhexylglycerin is a multifunctional glyceryl ether used in cosmetics primarily as a preservative-enhancing agent and emollient, often paired with phenoxyethanol to broaden antimicrobial efficacy. It also acts as a deodorizing agent and humectant in skincare formulations. |
| Calcium Chloride Viscosity/texture modifier & astringent | Calcium chloride is an inorganic salt used in skincare primarily to adjust viscosity, act as a mild astringent, and serve as a source of calcium ions in formulations. It is generally considered a functional/formulation ingredient rather than a therapeutic active. |
| Potassium Sorbate Preservative | Potassium sorbate is the potassium salt of sorbic acid, used as a mild preservative to inhibit mold, yeast, and some bacterial growth in cosmetic formulations. It is most effective at acidic pH and is often combined with other preservatives for broad-spectrum protection. |
| Citric Acid pH adjuster / AHA exfoliant | Citric acid is an alpha-hydroxy acid derived from citrus fruits, used primarily to adjust and buffer formulation pH and as a chelating agent, and at higher concentrations as a mild chemical exfoliant. It can promote surface cell turnover and is sometimes included in antioxidant or brightening products. |
