Rhamnose is a naturally occurring plant-derived monosaccharide used in skincare for its anti-aging and soothing properties, with research suggesting it may help stimulate collagen and reduce signs of skin aging. It is also reported to support skin barrier function and reduce inflammation.
Fructooligosaccharides are plant-derived prebiotic carbohydrates used in skincare to selectively nourish beneficial skin microbiota and support skin barrier health. They also provide mild humectant and soothing properties in topical formulations.
Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products.
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 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 transient skin irritation or stinging | Rare | Typically minor and self-limiting, more likely on compromised skin |
| Allergic contact dermatitis | Very rare | Sugar alcohols are uncommon sensitizers; isolated reports only |
| Mild skin irritation | Uncommon | Generally well tolerated; transient irritation possible, more likely in sensitive or compromised skin. |
| Eye irritation | Uncommon | Surfactant properties can cause stinging or irritation on direct ocular contact. |
| Enhanced penetration of other ingredients | Common | Not an adverse effect per se, but as a solubilizer it may increase absorption of co-formulated substances. |
| Skin irritation or mild stinging | Rare | Uncommon and typically mild when applied topically; more often reported with high concentrations. |
| Transient redness | Rare | Generally resolves quickly without intervention. |
| Mild transient irritation or redness | Rare | Occasionally reported at application site, usually self-limiting |
| Contact allergy or sensitization | Very rare | Isolated reports; uncommon for this class of ingredient |

| 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. |
| 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. |
| Xylitol Humectant / moisturizer | Xylitol is a sugar alcohol used in topical formulations as a humectant that helps attract and retain moisture in the skin, and it may support the skin's microbiome and barrier function. It is generally well tolerated and considered safe for topical use. |
| 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. |
| Mannitol Humectant/antioxidant | Mannitol is a sugar alcohol (polyol) used in skincare primarily as a humectant and texture-enhancing agent, and it also functions as a free-radical scavenger. It is generally considered a base/formulation ingredient rather than a therapeutic active. |
| Rhamnose Key active Anti-aging / soothing sugar | Rhamnose is a naturally occurring plant-derived monosaccharide used in skincare for its anti-aging and soothing properties, with research suggesting it may help stimulate collagen and reduce signs of skin aging. It is also reported to support skin barrier function and reduce inflammation. |
| Fructooligosaccharides Key active Prebiotic / humectant | Fructooligosaccharides are plant-derived prebiotic carbohydrates used in skincare to selectively nourish beneficial skin microbiota and support skin barrier health. They also provide mild humectant and soothing properties in topical formulations. |
| Cucumis Sativus Fruit Extract Soothing/hydrating botanical extract | Cucumis Sativus (cucumber) fruit extract is used in skincare for its hydrating, soothing, and mild antioxidant properties. It is commonly added to formulations to provide a cooling, calming sensation and to support skin moisture. |
| PEG-40 Hydrogenated Castor Oil Solubilizer/emulsifier | PEG-40 Hydrogenated Castor Oil is a nonionic surfactant derived from hydrogenated castor oil reacted with ethylene oxide, widely used to dissolve fragrances and oils into water-based formulations and to stabilize emulsions. It functions as a base/formulation ingredient rather than a treatment active. |
| Allantoin Key active Soothing/skin-conditioning agent | Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products. |
| 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. |
| Disodium EDTA Chelating agent | Disodium EDTA is a chelating agent used in cosmetics to bind metal ions, improving product stability, preventing rancidity, and enhancing the efficacy of preservatives. It is a formulation/base ingredient rather than a treatment active. |
| Cetrimonium Bromide Surfactant / preservative | Cetrimonium Bromide is a quaternary ammonium cationic surfactant used in cosmetics as an antimicrobial preservative, antistatic agent, and conditioning ingredient, particularly in hair-care formulations. It also imparts emulsifying and detangling properties. |
| Sodium Hydroxide pH adjuster | Sodium hydroxide (lye) is a strong alkaline compound used in small amounts to adjust and stabilize the pH of cosmetic formulations. At regulated low concentrations in finished products it is considered safe, though it is corrosive in concentrated form. |
| 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. |
