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.
Arbutin is a naturally derived hydroquinone glycoside used to reduce hyperpigmentation by inhibiting tyrosinase, the enzyme involved in melanin synthesis. It is commonly used to fade dark spots, melasma, and uneven skin tone.
N-Acetylglucosamine is an amino sugar and precursor to hyaluronic acid that is used in skincare to support hydration and reduce hyperpigmentation, particularly when combined with niacinamide. It may also inhibit tyrosinase activity, helping to even skin tone.
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.
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 |
|---|---|---|
| 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 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 redness | Uncommon | Typically transient and dose-dependent, more likely at higher concentrations. |
| Contact dermatitis | Rare | Allergic or irritant reactions reported in sensitive individuals. |
| Hydroquinone-related concerns from breakdown | Rare | Arbutin can hydrolyze to hydroquinone; theoretical risk of associated effects with high or prolonged exposure. |
| Paradoxical hyperpigmentation | Very rare | Reported anecdotally, similar to other depigmenting agents, usually with misuse. |
| Mild skin irritation or stinging | Uncommon | Typically transient and concentration-dependent, more likely on sensitive skin. |
| Erythema (redness) | Rare | Usually mild and self-resolving. |

| Ingredient | What it does |
|---|---|
| 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. |
| 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. |
| Arbutin Key active Skin-brightening agent | Arbutin is a naturally derived hydroquinone glycoside used to reduce hyperpigmentation by inhibiting tyrosinase, the enzyme involved in melanin synthesis. It is commonly used to fade dark spots, melasma, and uneven skin tone. |
| N-Acetylglucosamine Key active Skin-conditioning / brightening agent | N-Acetylglucosamine is an amino sugar and precursor to hyaluronic acid that is used in skincare to support hydration and reduce hyperpigmentation, particularly when combined with niacinamide. It may also inhibit tyrosinase activity, helping to even skin tone. |
| 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. |
| Dicarprylyl Ether Emollient / solvent | Dicaprylyl ether is a lightweight, fast-spreading emollient derived from caprylic alcohol, used to improve skin feel and act as a non-greasy spreading agent in cosmetic formulations. It also functions as a solvent and helps disperse other ingredients evenly across the skin. |
| 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. |
| Polysorbate 60 Emulsifier / surfactant | Polysorbate 60 is a nonionic surfactant and emulsifier derived from sorbitol and stearic acid, used to blend oil and water phases and stabilize emulsions in creams and lotions. It functions as a formulation aid rather than a therapeutic active. |
| 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. |
| 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. |
| Polyacrylate Crosspolymer-6 Film-forming/sensory-enhancing rheology modifier | Polyacrylate Crosspolymer-6 is a synthetic crosslinked acrylate polymer used in skincare and cosmetic formulations to provide a smooth, silky sensory feel, stabilize emulsions, and help form a light film on the skin. It is a formulation aid rather than a biologically active treatment ingredient. |
| 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. |
| 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. |
| 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. |
| 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. |
