Camellia Sinensis Leaf Extract (green tea extract) is derived from the leaves of the tea plant and is rich in polyphenols, particularly catechins like EGCG. It is used in skincare for its antioxidant, anti-inflammatory, and soothing properties.
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.
Acetyl Tetrapeptide-11 is a synthetic peptide marketed to support skin firmness by stimulating syndecan-1 and collagen-anchoring proteins, helping reinforce the dermal-epidermal junction. It is typically used in leave-on cosmetic formulations at low concentrations for firming and elasticity claims.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Allergic contact dermatitis | Rare | Documented in patch-test studies but considered a relatively weak sensitizer. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| 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 irritation or transient redness | Rare | Generally well tolerated; occasional sensitivity in predisposed individuals. |
| Comedogenicity / clogged pores | Rare | Considered low-comedogenic, but heavy oils may aggravate acne-prone skin in some users. |
| Mild skin irritation | Rare | Transient redness or stinging, typically in sensitive or compromised skin. |
| Contact dermatitis / allergic sensitization | Very rare | Isolated reports; uncommon compared with other glycols. |
| Eye irritation | Uncommon | Can cause stinging on direct ocular contact during application. |
| Skin irritation (mild redness or stinging) | Uncommon | Generally well tolerated; transient irritation may occur, particularly at higher concentrations or on compromised skin. |

| Ingredient | What it does |
|---|---|
| Water Solvent/vehicle | Water is the most common base ingredient in cosmetic formulations, serving as a solvent that dissolves other ingredients and forms the bulk of emulsions and aqueous solutions. It is generally considered safe and non-irritating. |
| Butylene Glycol Humectant / solvent | Butylene glycol is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent that helps dissolve other ingredients and improve skin feel. It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations. |
| 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. |
| Limnanthes Alba Seed Oil Emollient / skin-conditioning oil | Limnanthes Alba (Meadowfoam) Seed Oil is a highly stable, long-chain fatty acid-rich plant oil used as an emollient and occlusive in skincare. It helps soften skin, reduce moisture loss, and improve product spreadability and oxidative stability. |
| Isopentyldiol Humectant / solvent | Isopentyldiol is a low-molecular-weight diol used in cosmetics as a humectant, solvent, and mild antimicrobial-boosting agent that improves the texture and stability of formulations. It also enhances penetration of other ingredients and contributes a light, non-greasy skin feel. |
| 1,2-Hexanediol Humectant / preservative booster | 1,2-Hexanediol is a synthetic diol used in skincare as a humectant and solvent that also enhances the antimicrobial efficacy of formulations, often allowing reduced or preservative-free systems. It helps maintain product stability while contributing mild moisturizing properties. |
| Squalane Emollient / occlusive moisturizer | Squalane is a saturated, stable hydrocarbon derived from squalene (sourced from plants like olives or sugarcane, or shark liver) used as a lightweight emollient that softens skin and reinforces the skin barrier by reducing transepidermal water loss. It is well tolerated, non-comedogenic for most users, and serves as a base or carrier ingredient rather than a therapeutic active. |
| Polyglyceryl-10 Stearate Emulsifier | Polyglyceryl-10 Stearate is a non-ionic emulsifier and surfactant derived from polyglycerol and stearic acid, used to blend oil and water phases and stabilize emulsions in skincare formulations. It is valued for its mildness and is common in formulations marketed as gentle or PEG-free. |
| Glyceryl Stearate Citrate Emulsifier / co-emulsifier | Glyceryl Stearate Citrate is a plant-derived ester of glycerin, stearic acid, and citric acid used to create stable oil-in-water emulsions. It functions as a non-ionic emulsifier and skin-conditioning agent in creams and lotions. |
| Sodium Stearoyl Glutamate Emulsifier / surfactant | Sodium Stearoyl Glutamate is a mild, amino-acid-derived (glutamic acid and stearic acid) anionic surfactant used primarily as an emulsifier and co-emulsifier to stabilize oil-in-water formulations. It is well tolerated and often chosen for gentle, naturally derived cosmetic systems. |
| Inulin Lauryl Carbamate Emulsifier / surfactant | Inulin Lauryl Carbamate is a plant-derived, sugar-based emulsifier produced by reacting inulin with lauryl groups. It is used to stabilize oil-in-water emulsions and improve texture in creams and lotions. |
| Glyceryl Caprylate Emollient / antimicrobial co-preservative | Glyceryl Caprylate is a monoglyceride derived from glycerin and caprylic acid, used in skincare as an emollient, moisturizing agent, and skin-conditioning component with mild antimicrobial properties that support preservation. It is commonly employed to help stabilize formulations and reduce reliance on conventional preservatives. |
| 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. |
| 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. |
| 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. |
| Carbomer Thickener / gelling agent | Carbomer is a synthetic high-molecular-weight polymer of acrylic acid used to thicken, stabilize, and control the viscosity of gels, creams, and lotions. It functions as a formulation aid rather than a therapeutic 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. |
