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.
Citrus Aurantium Dulcis (sweet orange) callus culture extract is a plant stem cell–derived ingredient obtained from cultured orange callus tissue, used in skincare for its antioxidant and skin-conditioning properties. It is promoted for protecting against oxidative stress and supporting skin vitality, though robust clinical evidence is limited.
Glutathione is a tripeptide antioxidant used in skincare for its melanin-modulating and antioxidant properties, often promoted to reduce hyperpigmentation and even skin tone. Topical efficacy data is limited and variable, with stronger systemic effects associated with oral or intravenous routes.
Acetyl cysteine (N-acetylcysteine) is a thiol-containing antioxidant and glutathione precursor used topically for its free-radical scavenging and skin-conditioning properties. It is studied for conditions such as melasma, acne, and barrier support.
Dimethylmethoxy Chromanol is a synthetic chroman-derived antioxidant (a vitamin E-related molecule) used in cosmetic formulations to neutralize free radicals and protect skin and product stability against oxidative damage. It is marketed for both lipophilic and hydrophilic environments, offering broad-spectrum protection against reactive oxygen and nitrogen species.
Ergothioneine is a naturally occurring, sulfur-containing amino acid derivative used in skincare as a potent antioxidant that helps protect skin cells from oxidative stress and may support skin barrier function. It is valued for its stability and ability to scavenge free radicals.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|

| 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. |
| 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. |

| 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. |
| Contact irritation | Rare | Mild redness or irritation possible, generally low risk as a refined wax. |
| Pore congestion / comedogenicity | Rare | Heavy waxes may contribute to clogged pores in acne-prone individuals. |

| Ingredient | What it does |
|---|---|
| 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. |
| 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. |
| 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. |
| Helianthus Annuus Seed Wax Emollient / thickener | Helianthus Annuus (Sunflower) Seed Wax is a plant-derived wax used in skincare and cosmetics primarily as a viscosity-increasing agent, emollient, and structuring component in balms, sticks, and creams. It helps stabilize formulations and provides a protective, conditioning film on the skin. |
| Polyglyceryl-10 Tristearate Emulsifier / surfactant | Polyglyceryl-10 Tristearate is a non-ionic, polyglycerol-based ester used as an oil-in-water emulsifier and texture enhancer in creams, lotions, and other skincare formulations. It helps stabilize emulsions and improve spreadability without strong sensorial or active treatment effects. |
| 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. |
| Dicaprylyl Ether Emollient/Skin-conditioning agent | Dicaprylyl ether is a lightweight, fast-spreading emollient derived from caprylic alcohol, used to improve skin feel and reduce greasiness in formulations. It functions as a non-occlusive carrier and texture enhancer rather than a treatment active. |
| Aqua (Water) Solvent/Base | Aqua (Water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble ingredients and provides the medium for emulsions. It carries active and functional components and influences product texture. |
| Caprylyl Glycol Humectant / skin-conditioning agent and preservative booster | Caprylyl glycol is a multifunctional emollient and humectant derived from caprylic acid that helps hydrate skin and enhance the efficacy of preservatives in formulations. It is widely used as a stabilizing and conditioning base ingredient rather than a therapeutic active. |
| Citrus Aurantium Dulcis Callus Culture Extract Key active Antioxidant / skin conditioning | Citrus Aurantium Dulcis (sweet orange) callus culture extract is a plant stem cell–derived ingredient obtained from cultured orange callus tissue, used in skincare for its antioxidant and skin-conditioning properties. It is promoted for protecting against oxidative stress and supporting skin vitality, though robust clinical evidence is limited. |

It is valued for its stability and ability to scavenge free radicals. |
| 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. |
| 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. |
| Leuconostoc/Radish Root Ferment Filtrate Natural preservative | Leuconostoc/Radish Root Ferment Filtrate is a fermentation-derived ingredient produced by culturing Leuconostoc bacteria on radish roots, yielding antimicrobial peptides used as a natural alternative to synthetic preservatives. It helps protect water-based cosmetic formulations from microbial growth while sometimes contributing mild conditioning properties. |
