Centella Asiatica Leaf Water is a water-based extract of the gotu kola plant valued for its soothing, antioxidant, and skin-conditioning properties attributed to triterpenoid compounds like madecassoside and asiaticoside. It is commonly used to calm irritation and support skin barrier function in topical formulations.
3-O-Ethyl Ascorbic Acid is a stable, water-soluble ethylated derivative of vitamin C that converts to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and pigmentation control. It is valued for greater stability than pure L-ascorbic acid while delivering similar brightening and anti-aging benefits.
Gluconolactone is a polyhydroxy acid that gently exfoliates the skin surface, provides antioxidant and humectant benefits, and is often considered milder than alpha hydroxy acids. It is well tolerated, including by sensitive skin, due to its larger molecular size and slower penetration.
Acetyl glucosamine is an amino sugar that serves as a precursor to hyaluronic acid and can help support skin hydration and barrier function. It is also studied for its ability to reduce hyperpigmentation by inhibiting melanin production, often used alongside niacinamide.
Lactic acid is an alpha-hydroxy acid that exfoliates the skin by loosening bonds between corneocytes, promoting cell turnover, and acting as a humectant to improve hydration, texture, and tone. It is commonly used at concentrations ranging from low (hydration) to higher peel-strength formulations.

| Reported effect | How often | Notes |
|---|---|---|
| Contact allergic dermatitis | Rare | Sensitization to Centella triterpenes can cause localized redness or itching in predisposed individuals. |
| Mild stinging or transient irritation | Uncommon | Usually associated with sensitive or compromised skin rather than the extract itself. |
| Contact urticaria | Very rare | Isolated case reports of hive-like reactions. |
| Mild stinging or tingling | Uncommon | More likely at higher concentrations or on sensitive or compromised skin. |
| Transient erythema (redness) | Uncommon | Usually temporary and resolves after discontinuation or lowering concentration. |
| Dryness or irritation | Uncommon | Can occur with frequent use or in combination with other actives. |
| Allergic contact dermatitis | Rare | Hypersensitivity reactions are infrequently reported. |
| Mild skin irritation | Uncommon | Possible at higher concentrations, particularly on sensitive or 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 skin irritation or stinging | Uncommon | May occur at higher concentrations or on compromised/sensitive skin. |
| Increased penetration-related irritation from co-formulated actives | Uncommon | By enhancing delivery, DMI can amplify irritancy of other ingredients in the product. |
| Contact dermatitis or allergic sensitization | Rare | Allergic reactions are infrequently reported in the literature. |
| Mild transient stinging or tingling | Common | Brief sensation on application, particularly at higher concentrations or on compromised skin. |
| Mild erythema (redness) | Uncommon | Usually temporary and resolves shortly after use. |
| Dryness or flaking | Uncommon | Related to its exfoliating action, more likely with frequent use. |
| Increased sun sensitivity | Uncommon | PHAs are generally less photosensitizing than AHAs, but sunscreen is still advised. |

| Centella Asiatica Leaf Water Key active Soothing/antioxidant botanical | Centella Asiatica Leaf Water is a water-based extract of the gotu kola plant valued for its soothing, antioxidant, and skin-conditioning properties attributed to triterpenoid compounds like madecassoside and asiaticoside. It is commonly used to calm irritation and support skin barrier function in topical formulations. |
| 3-O-Ethyl Ascorbic Acid Key active Antioxidant / brightening vitamin C derivative | 3-O-Ethyl Ascorbic Acid is a stable, water-soluble ethylated derivative of vitamin C that converts to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and pigmentation control. It is valued for greater stability than pure L-ascorbic acid while delivering similar brightening and anti-aging benefits. |
| 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. |
| 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. |
| Gluconolactone Key active Polyhydroxy acid (PHA) exfoliant/humectant | Gluconolactone is a polyhydroxy acid that gently exfoliates the skin surface, provides antioxidant and humectant benefits, and is often considered milder than alpha hydroxy acids. It is well tolerated, including by sensitive skin, due to its larger molecular size and slower penetration. |
| 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. |
| Sodium Gluconate Chelating agent / skin-conditioning | Sodium gluconate is the sodium salt of gluconic acid used in skincare primarily as a chelating agent to bind metal ions and stabilize formulations, with secondary humectant and skin-conditioning properties. It is generally considered a base/formulation ingredient rather than an active treatment. |
| Acetyl Glucosamine Key active Skin-conditioning / exfoliant precursor | Acetyl glucosamine is an amino sugar that serves as a precursor to hyaluronic acid and can help support skin hydration and barrier function. It is also studied for its ability to reduce hyperpigmentation by inhibiting melanin production, often used alongside niacinamide. |
| Sodium Hyaluronate Humectant / hydrator | Sodium hyaluronate is the sodium salt of hyaluronic acid, a glycosaminoglycan that attracts and binds water to the skin to improve hydration and surface plumpness. Its lower molecular weight allows better penetration than native hyaluronic acid. |
| Pullulan Film-forming agent / texturizer | Pullulan is a naturally derived polysaccharide produced by fermentation of starch by the fungus Aureobasidium pullulans. In skincare it forms a thin, breathable film on the skin, providing a temporary tightening or smoothing effect and helping to stabilize formulations. |
| Hydroxyethylcellulose Thickener/viscosity modifier | Hydroxyethylcellulose is a non-ionic, water-soluble cellulose derivative used to thicken, stabilize, and adjust the texture of aqueous cosmetic formulations. It functions as a gelling and film-forming agent rather than providing a direct biological skin benefit. |
| 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. |
| Sclerotium Gum Thickener / stabilizer | Sclerotium Gum is a natural polysaccharide produced by fermentation of the fungus Sclerotium rolfsii, used as a thickening, gelling, and emulsion-stabilizing agent in cosmetic formulations. It also imparts a smooth skin feel and helps suspend particles in creams, gels, and serums. |
| 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. |
| 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. |
