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%.
Caffeine is a topical active used in skincare for its antioxidant properties and ability to constrict blood vessels, which may temporarily reduce puffiness and the appearance of under-eye darkness. It is also studied for reducing localized fluid retention and protecting against UV-induced oxidative stress.
Troxerutin is a semi-synthetic flavonoid (a hydroxyethyl derivative of rutin) used topically for its antioxidant and capillary-strengthening properties, often targeting redness, microcirculation, and signs of vascular fragility. It is also used systemically for venous and microvascular conditions.
Sarcosine is an amino acid derivative (N-methylglycine) used in skincare primarily to help regulate sebum production and reduce skin oiliness, and it also serves as a building block for milder surfactants like sodium sarcosinate. It is most commonly incorporated into formulations targeting oily and acne-prone skin.
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.
Adenosine is a nucleoside that signals through cell-surface receptors to promote dermal fibroblast activity and collagen/elastin production, helping reduce the appearance of fine lines and wrinkles. It also has anti-inflammatory and soothing properties at low concentrations commonly used in cosmetics (around 0.04-0.1%).

It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations. |
| 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. |
| 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. |
| Bis-Peg-18 Methyl Ether Dimethyl Silane Emollient/conditioning agent | Bis-PEG-18 Methyl Ether Dimethyl Silane is a PEG-modified silane used in skincare and cosmetics primarily as a skin-conditioning agent and emollient that imparts a smooth, silky feel while improving spreadability of formulations. It is water-dispersible and commonly found in moisturizers, serums, and primers as part of the formulation base rather than as a therapeutic 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. |
| Caffeine Key active Antioxidant / vasoconstrictor | Caffeine is a topical active used in skincare for its antioxidant properties and ability to constrict blood vessels, which may temporarily reduce puffiness and the appearance of under-eye darkness. It is also studied for reducing localized fluid retention and protecting against UV-induced oxidative stress. |
| Polysorbate 20 Emulsifier / solubilizer | Polysorbate 20 is a nonionic surfactant derived from sorbitol and lauric acid, used in skincare to solubilize fragrances and essential oils and to stabilize oil-in-water emulsions.
