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.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
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.
Terminalia Ferdinandiana (Kakadu plum) fruit extract is an exceptionally rich natural source of vitamin C (ascorbic acid) along with ellagic and gallic acids, valued in skincare for antioxidant protection and potential brightening effects. It helps neutralize free radicals and may support collagen-related processes when stabilized in formulations.
Centella Asiatica Extract is a plant-derived ingredient rich in triterpenoids (asiaticoside, madecassoside, asiatic and madecassic acids) used to calm inflammation, support wound healing, and strengthen the skin barrier. It is also valued for antioxidant and collagen-supporting properties in topical formulations.
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.
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 or stinging | Common | More likely at higher concentrations or on compromised/sensitive skin |
| Allergic contact dermatitis | Uncommon | Recognized contact allergen; confirmed via patch testing |
| Irritant contact dermatitis | Uncommon | Non-allergic irritation, often dose-dependent |
| Worsening of pre-existing eczema or barrier-impaired skin | Rare | Penetration-enhancing effect may increase reactivity |
| Systemic toxicity from topical use | Very rare | Reported mainly with extensive application on broken skin, especially in infants or burn patients |
| 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. |
| Mild transient flushing or redness | Uncommon | More likely at higher concentrations or in sensitive skin; usually subsides quickly. |
| Tingling, stinging, or burning sensation | Uncommon | Often associated with higher percentages or compromised barrier. |
| Contact irritation or itching | Rare | Generally dose-dependent and resolves with discontinuation. |
| Mild skin irritation or redness | Uncommon | May occur with topical application, particularly in sensitive skin. |
| Contact allergic reaction | Rare | Sensitization to the ingredient or formulation components is possible. |
| Skin lightening beyond intended areas / uneven results | Rare | Reported mainly with systemic use rather than topical. |
| Serious adverse events such as skin rashes, organ effects, or Stevens-Johnson syndrome | Very rare | Primarily linked to intravenous/injectable use, which lacks regulatory approval for skin lightening in many regions. |

| 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. |
| 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. |
| 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. |
| Niacinamide Key active Cell-communicating / barrier-repair active | Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%. |
| Glutathione Key active Antioxidant / skin-brightening agent | 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. |
| Terminalia Ferdinandiana Fruit Extract Key active Antioxidant | Terminalia Ferdinandiana (Kakadu plum) fruit extract is an exceptionally rich natural source of vitamin C (ascorbic acid) along with ellagic and gallic acids, valued in skincare for antioxidant protection and potential brightening effects. It helps neutralize free radicals and may support collagen-related processes when stabilized in formulations. |
| Centella Asiatica Extract Key active Soothing/antioxidant active | Centella Asiatica Extract is a plant-derived ingredient rich in triterpenoids (asiaticoside, madecassoside, asiatic and madecassic acids) used to calm inflammation, support wound healing, and strengthen the skin barrier. It is also valued for antioxidant and collagen-supporting properties in topical formulations. |
| 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. |
| 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. |
| 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. |
| Methylisothiazolinone Preservative | Methylisothiazolinone (MI) is a synthetic isothiazolinone preservative used in cosmetics and personal care products to prevent microbial growth. It is effective at low concentrations but is recognized as a significant contact allergen. |
