Ascorbic acid (vitamin C) is a water-soluble antioxidant used in skincare to neutralize free radicals, inhibit melanin synthesis, and support collagen production. It is valued for brightening, evening skin tone, and protecting against photodamage when used alongside sunscreen.
Hyaluronic acid is a glycosaminoglycan that attracts and binds water to the skin, helping to maintain hydration and improve the appearance of plumpness and smoothness. It is widely used in moisturizers and serums and is generally well tolerated across skin types.
Tocopherol (vitamin E) is a lipid-soluble antioxidant used in skincare to protect skin and formulations from oxidative damage caused by free radicals and UV exposure. It also functions as a skin-conditioning and emollient agent and can stabilize oils against rancidity.
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 contact irritation | Rare | Occasional redness or stinging, usually in sensitive or compromised skin. |
| Allergic contact dermatitis | Very rare | Isolated case reports; considered a low-sensitizing ingredient. |
| Comedogenicity / clogged pores | Rare | Generally low comedogenic potential, but acne-prone individuals may occasionally react. |
| Mild skin irritation | Rare | Occasional transient irritation reported in sensitive individuals. |
| Comedogenicity (pore clogging) | Rare | Low comedogenic potential but possible in acne-prone skin. |
| Comedogenicity | Rare | Low comedogenic potential; clogged pores possible in acne-prone individuals with rich formulations. |
| 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. |
| Skin dryness or tightness | Common | Due to its oil-absorbing properties, especially with frequent use or on already dry skin. |
| Mild irritation or redness | Uncommon | More likely with abrasive particles or sensitive skin types. |
| Micro-abrasions from mechanical scrubbing | Uncommon | Coarse particles can cause minor surface damage if applied with excessive pressure. |
| Worsening of compromised skin barrier | Rare | In conditions like eczema or rosacea, exfoliation and absorption may aggravate symptoms. |

| 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. |
| Caprylic/Capric Triglyceride Emollient / skin-conditioning agent | Caprylic/Capric Triglyceride is a lightweight emollient derived from coconut or palm oil and glycerin, used to soften skin, improve spreadability, and act as a solvent for oil-soluble ingredients. It is well-tolerated and serves primarily as a base ingredient rather than an active. |
| Isoamyl Laurate Emollient | Isoamyl Laurate is a plant-derived ester (from isoamyl alcohol and lauric acid) used as a lightweight, fast-spreading emollient that improves skin feel and product texture. It functions to soften and condition the skin and acts as a natural alternative to silicones. |
| Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate Emulsifier (W/O) | Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate is a polyglycerol-based oligomeric emulsifier used to stabilize water-in-oil emulsions in creams, lotions, and sunscreens. It is a formulation/base ingredient that creates smooth, stable emulsions without contributing direct therapeutic skin activity. |
| 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. |
| Volcanic Soil Absorbent/exfoliant | Volcanic soil (volcanic ash or mud) is a mineral-rich powder used in cleansers and masks to absorb excess sebum and provide gentle mechanical exfoliation. It is valued for its porous structure and trace mineral content. |
| Squalane Emollient / occlusive moisturizer | Squalane is a saturated, stable hydrocarbon derived from squalene (sourced from plants like olives or sugarcane, or shark liver) used as a lightweight emollient that softens skin and reinforces the skin barrier by reducing transepidermal water loss. It is well tolerated, non-comedogenic for most users, and serves as a base or carrier ingredient rather than a therapeutic active. |
| Magnesium Sulfate Emulsion stabilizer / viscosity-adjusting agent | Magnesium sulfate is an inorganic salt used in cosmetic formulations primarily as an emulsion stabilizer, viscosity controller, and bulking agent, particularly in water-in-oil systems. It is generally considered safe and well tolerated in topical skincare products. |
| Ascorbic Acid Key active Antioxidant / brightening active | Ascorbic acid (vitamin C) is a water-soluble antioxidant used in skincare to neutralize free radicals, inhibit melanin synthesis, and support collagen production. It is valued for brightening, evening skin tone, and protecting against photodamage when used alongside sunscreen. |
| Hyaluronic Acid Key active Humectant / hydrating agent | Hyaluronic acid is a glycosaminoglycan that attracts and binds water to the skin, helping to maintain hydration and improve the appearance of plumpness and smoothness. It is widely used in moisturizers and serums and is generally well tolerated across skin types. |
| Amylopectin Thickener / film-former | Amylopectin is a highly branched polysaccharide derived from starch, used in skincare as a natural thickening agent, film-former, and absorbent that imparts a smooth, mattifying feel to formulations. It is considered a base/formulation ingredient rather than an active treatment ingredient. |
| 1,2-Hexanediol Humectant / preservative booster | 1,2-Hexanediol is a synthetic diol used in skincare as a humectant and solvent that also enhances the antimicrobial efficacy of formulations, often allowing reduced or preservative-free systems. It helps maintain product stability while contributing mild moisturizing properties. |
| 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. |
| 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. |
| Tocopherol Key active Antioxidant | Tocopherol (vitamin E) is a lipid-soluble antioxidant used in skincare to protect skin and formulations from oxidative damage caused by free radicals and UV exposure. It also functions as a skin-conditioning and emollient agent and can stabilize oils against rancidity. |
| 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. |
