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 skin irritation | Uncommon | Transient stinging or redness, more likely on compromised or sensitive skin. |
| Allergic contact dermatitis | Rare | Sensitization is infrequent; propanediol is generally considered low-risk for allergy. |
| Enhanced penetration of co-formulated irritants | Uncommon | As a penetration enhancer it may increase absorption and irritation potential of other actives. |
| 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. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Contact dermatitis / skin irritation | Rare | Possible in individuals sensitive to Brassicaceae (cruciferous) plants. |
| Allergic reaction / sensitization | Rare | Botanical extracts can occasionally trigger hypersensitivity responses. |
| Redness or stinging | Very rare | Generally mild and transient when reported. |
| Skin dryness | Uncommon | Its solvent action may contribute to dryness with repeated use in some individuals. |
| Eye irritation | Uncommon | Can cause irritation on direct ocular contact, relevant in eye-area products. |
| Systemic toxicity | Very rare | Of theoretical concern with large-scale ingestion or extreme exposure; not associated with normal topical cosmetic use. |

| 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. |
| 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. |
| 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. |
| Butylene Glycol Humectant / solvent | Butylene glycol is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent that helps dissolve other ingredients and improve skin feel. It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations. |
| Nasturtium Officinale Leaf/Stem Extract Key active Antioxidant / skin conditioning | Nasturtium Officinale (watercress) Leaf/Stem Extract is a botanical extract rich in vitamins, minerals, and antioxidant compounds, used in skincare for its conditioning, soothing, and brightening properties. It is valued for its content of vitamin C, glucosinolates, and flavonoids that may help protect against oxidative stress. |
| Diethylene Glycol Monoethyl Ether Solvent / penetration enhancer | Diethylene glycol monoethyl ether (ethoxydiglycol) is a versatile solvent and penetration enhancer used in cosmetic and topical formulations to dissolve active ingredients and improve their absorption into the skin. It also functions as a viscosity reducer and coupling agent in mixed-phase products. |
| Sodium Metabisulfite Antioxidant/preservative | Sodium metabisulfite is an inorganic salt used in cosmetic and topical formulations primarily as an antioxidant and preservative to prevent oxidation and discoloration of products. It releases sulfur dioxide, which helps stabilize sensitive ingredients. |
| Glycine Amino acid / humectant | Glycine is a small amino acid used in skincare as a humectant and conditioning agent, supporting skin hydration and acting as a building block for collagen and natural moisturizing factor. It is generally considered well-tolerated and is often included as part of moisturizing or barrier-support formulations. |
| Larix Europaea Wood Extract Skin conditioning / antioxidant | Larix Europaea (European larch) Wood Extract is a plant-derived ingredient rich in arabinogalactan polysaccharides and polyphenols, used in skincare for its conditioning, soothing, and antioxidant properties. It is also valued as a humectant and film-forming agent that can support skin hydration. |
| Zinc Chloride Key active Astringent/antimicrobial | Zinc chloride is an inorganic zinc salt used in skincare and topical formulations as an astringent and antimicrobial agent, and in higher concentrations as a caustic/escharotic in dermatologic procedures. It can help reduce surface microbial load and tighten tissue. |
| Camellia Sinensis Leaf Extract Key active Antioxidant | Camellia Sinensis Leaf Extract (green tea extract) is derived from the leaves of the tea plant and is rich in polyphenols, particularly catechins like EGCG.
