Saccharum Officinarum (Sugarcane) Extract is derived from sugarcane and contains natural sugars and glycolic acid, contributing humectant and mild exfoliating properties. It is often included in skincare for hydration and to support gentle surface renewal.
Protease is a proteolytic enzyme used in skincare to break down peptide bonds in the proteins of the stratum corneum, promoting gentle exfoliation of dead surface skin cells. It is valued as an alternative to acid-based or physical exfoliation.
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 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. |
| Skin dryness or tightness | Rare | Possible with high concentrations in leave-on products. |
| Redness or erythema | Uncommon | Typically mild and resolves after discontinuation. |
| Mild skin irritation | Uncommon | Transient stinging or redness, more likely on compromised or sensitive skin. |
| Enhanced penetration of co-formulated irritants | Uncommon | As a penetration enhancer it may increase absorption and irritation potential of other actives. |
| Contact irritation or mild redness | Rare | Occasional sensitivity reported, typically in individuals with reactive skin. |
| Mild skin irritation or stinging | Uncommon | More likely on sensitive or compromised skin, partly due to glycolic acid content. |
| Redness or transient erythema | Uncommon | Usually mild and resolves shortly after application. |
| Increased photosensitivity | Uncommon | Associated with AHA activity; sunscreen use is advised. |

| Ingredient | What it does |
|---|---|
| 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. |
| Pentylene Glycol Humectant / solvent / preservative-booster | Pentylene glycol is a glycol used in cosmetics as a humectant and solvent that also enhances the antimicrobial efficacy of formulations, helping reduce reliance on traditional preservatives. It improves skin hydration and aids the delivery and stability of other ingredients. |
| 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. |
| Chondrus Crispus Extract Humectant/film-former | Chondrus Crispus Extract, derived from red algae (Irish moss), is used in skincare as a hydrating agent, film-forming and thickening polysaccharide that helps bind water and improve skin smoothness. It also contributes emollient and soothing properties to formulations. |
| Saccharum Officinarum (Sugarcane) Extract Key active Humectant / natural exfoliant (AHA source) | Saccharum Officinarum (Sugarcane) Extract is derived from sugarcane and contains natural sugars and glycolic acid, contributing humectant and mild exfoliating properties. It is often included in skincare for hydration and to support gentle surface renewal. |
| Sea Water Skin-conditioning agent / mineral-rich solvent | Sea water is a naturally sourced ingredient containing minerals such as magnesium, calcium, potassium, and sodium, used in skincare for its hydrating and skin-conditioning properties. It is generally used as a functional base or conditioning component rather than a targeted treatment active. |
| 2-Hexanediol Humectant/preservative-booster | 1,2-Hexanediol (commonly written 2-hexanediol) is a multifunctional diol used in skincare primarily as a humectant, solvent, and preservative-enhancing agent that improves the antimicrobial efficacy of formulations. It is generally well tolerated and considered a base/formulation ingredient rather than a treatment active. |
| Protease Key active Enzymatic exfoliant | Protease is a proteolytic enzyme used in skincare to break down peptide bonds in the proteins of the stratum corneum, promoting gentle exfoliation of dead surface skin cells. It is valued as an alternative to acid-based or physical exfoliation. |
| Betaine Humectant / osmolyte | Betaine is a naturally derived amino acid derivative (trimethylglycine) used in skincare as a humectant and osmoprotectant that attracts and retains moisture while helping stabilize skin barrier function. It also improves the texture and mildness of formulations. |
| Panthenol Humectant / skin-conditioning agent | Panthenol (provitamin B5) is converted to pantothenic acid in the skin, where it acts as a humectant and helps support skin barrier function and hydration. It is also used for its soothing and mild anti-inflammatory properties in topical formulations. |
| 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. |
| 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. |
| 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. |
| 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. |
