| Ingredient | What it does |
|---|---|
| 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. |
| 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%. |
| 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. |
| 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. |
| 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. |
| Polyglyceryl-10 Laurate Emulsifier / surfactant | Polyglyceryl-10 Laurate is a non-ionic ester of polyglycerin and lauric acid used as a gentle emulsifier and mild surfactant in skincare and cosmetic formulations. It helps stabilize oil-in-water systems and can act as a solubilizer or cleansing agent. |
| Trehalose Humectant / moisturizer | Trehalose is a naturally occurring disaccharide used in skincare as a humectant and protective agent, helping retain moisture and stabilize cell membranes and proteins against dehydration and oxidative stress. It is well tolerated and commonly used to support skin barrier hydration. |
| 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. |
| 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. |
