Dark Circle Eye Cream

The base most products are built on. It carries the other ingredients and has no safety concern.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A fatty alcohol used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

A lightweight, odorless emollient made by combining coconut or palm-derived fatty acids with glycerin. It spreads easily, feels non-greasy, and has a long history of use in skin and hair products with no meaningful irritation or sensitization signal.

A mixture of lightweight hydrocarbons derived from mineral oil or plants. It is biologically inert, non-irritating, and widely used in moisturizers and primers to improve texture without leaving residue.

A rich plant butter pressed from shea tree nuts, valued for softening and cushioning dry skin. It is generally well tolerated, though very rare allergic reactions have been reported and people with tree nut allergies who are cautious may want to patch test first.

A plant-derived water or extract used mainly as a soothing humectant filler. Evidence for dramatic skin benefits beyond mild hydration and soothing is limited, but it is well tolerated by most people.

A peptide lipid that mimics collagen fragments and signals skin cells to increase collagen production while reducing inflammation. Established in anti-aging formulas with a consistent safety record.

Palmitoyl Oligopeptide attaches a fatty palmitic acid tail to a short synthetic peptide, a design used in anti-aging serums to signal skin cells, including as one component of the widely marketed Matrixyl 3000 complex. CIR's review of palmitoyl oligopeptides as a class did not identify a safety signal, and as a large synthetic peptide it is not expected to cross intact skin in meaningful amounts. Independently published clinical evidence on how well any single palmitoyl peptide performs is thinner than the marketing built around it.

A common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

Synthetic Beeswax is a manufactured blend of long-chain esters designed to mimic natural beeswax's texture and melting point, used as an emulsion stabilizer and thickener in balms, sticks, and creams. CIR reviewed it alongside other cosmetic waxes and concluded it is safe as used, a conclusion the panel revisited and left unchanged after a later look at additional data.

A water or bran extract of rice containing ferulic acid, small peptides and starches. It is a traditional East Asian skincare staple with some supporting antioxidant and mild-brightening data, but most of that evidence comes from cell or animal studies rather than large human trials, so the "brightening" claims on finished products go further than the direct evidence.

Rosemary extract is widely used at low levels as a natural antioxidant to help stabilize oils and extend product shelf life, in addition to appearing as an active botanical in some formulas. It is generally well tolerated, with occasional mild contact reactions reported, mostly at higher leave-on concentrations.

A lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

A widely used emulsifier and solubilizer that has been in cosmetics and pharmaceuticals for decades. The CIR has assessed it as safe with no known concerns at typical cosmetic concentrations. As with any surfactant, some people with very sensitive skin may experience mild irritation.

Carbomer is a synthetic polymer used purely to thicken and stabilize gels and lotions, with negligible skin penetration due to its large molecular size. Safety reviews have found low toxicity and minimal irritation potential even in leave-on use.

An amino acid-derived chelating agent that stabilizes formulas by binding trace metals. Published assessments support its use at cosmetic concentrations.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

This small glycol is used to thin out formulas and help preservatives work better, similar in role to propylene glycol and butylene glycol already in wide use. Industry and EU safety reviewers have set purity and concentration conditions for its use rather than restricting it outright, and no consumer-relevant hazard has been established at typical cosmetic levels.

A strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.
