Eyes Ultimate Eye Cream

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

A silicone with vinyl groups used in long-wear primers and foundations for enhanced adherence and smoothness. It is inert and well tolerated at cosmetic concentrations.

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

A form of vitamin B3 used to support a more even-looking tone and a comfortable barrier. Well tolerated at cosmetic levels.

This branched hydrocarbon is one of the isoparaffins the CIR Expert Panel reviewed and found safe as used in cosmetics, including as an emollient in leave-on face creams. It is generally considered non-comedogenic and used mainly to give a lightweight, non-greasy skin feel.

A fatty acid ester derived from isostearic acid and isopropyl alcohol, valued for its lightweight emollient properties and smooth feel on skin. It is an inert conditioning agent with minimal risk of irritation at typical cosmetic use levels.

A fatty alcohol derived from stearic acid that thickens creams and gives them a smooth, non-greasy glide. It is one of the fatty alcohols the CIR panel reviewed together and found safe as used, with a very low reported rate of contact sensitization.

A five-amino-acid peptide lipid that stimulates collagen and elastin synthesis. One of the most established peptides in cosmetics with decades of safe use and no reported sensitization issues.

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

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

A long-chain fatty alcohol used to thicken and stabilize creams and soften skin. It is a waxy emollient, not a drying solvent, and is graded low concern in published assessments.

A synthetic polymer used to thicken gels and creams. The CIR panel confirmed it is safe as used in cosmetics. Rarely, contact sensitization has been reported in people with existing dermatitis, though the monomer residual content in cosmetic-grade material is tightly controlled.

A hydrocarbon solvent derived from mineral oil, used to thin formulas and help ingredients blend. CIR has determined it is safe as used. It is inert, does not penetrate skin meaningfully, and rinses off or evaporates completely.

A common preservative and fragrance/solvent ingredient found naturally in many essential oils. It is well tolerated by most people at the levels used in cosmetics, but it is one of the 26 EU-designated fragrance allergens and can trigger reactions in people with an existing sensitivity.

A preservative that keeps products free of mold and bacteria. Reviewed repeatedly and considered safe at the low levels used.

A PEG-based emulsifier that blends oils and water in formulas. It is a workhorse ingredient in stable emulsions and is approved for cosmetic use. Well tolerated.

Dimethiconol is a silicone emollient closely related to dimethicone, used to add slip and a smooth finish to creams and serums. It shares dimethicone's long-standing safety record and is considered non-sensitizing and non-comedogenic in typical use.

A member of the paraben family used to prevent microbial growth in cosmetics. Like methylparaben, it has been reviewed extensively and found safe at the concentrations used in leave-on and rinse-off products.

A naturally occurring fatty acid (also made in the body and found in many foods) used to thicken lotions and help stabilize cleansing bars. It is one of the most well-studied emollient ingredients and is not a meaningful irritant at cosmetic use levels.

A natural, plant-based emulsifier made from cetyl alcohol and glucose that mixes oil and water phases in cosmetics. It is well studied, nonirritating in published testing, and presents no known safety concerns for cosmetic use.

A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.

A polyethylene glycol ether of lauryl alcohol, used as a mild surfactant and emulsifier in cleansers and other rinse-off products. CIR assessments support the safety of laureth surfactants in cosmetics, and they are often chosen for their mildness.

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.

Mineral pigments used to add color to cosmetics. Iron oxides are FDA-approved colorants with a well-established safety record in cosmetic formulations.
