Derm Correxion Neck Cream With Hyaluronic Acid And Advanced Retinol

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

A multi-ester emollient created from pentaerythritol and ethylhexanoic acid. It provides silky texture and skin conditioning with no documented safety concerns at cosmetic concentrations.

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

A lightweight polyethylene glycol that draws moisture into skin and helps dissolve other ingredients. Published safety reviews support its use; concerns about absorption through skin are overstated for leave-on formulations.

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.

A starch derivative used in cosmetics to thicken formulations and improve texture. It has been used safely in food and cosmetics for decades and shows low irritation potential across rinse-off and leave-on products.

A lightweight, volatile silicone that gives serums and primers their silky slip and quick-evaporating finish. Human safety data are reassuring; the EU restriction on this ingredient in rinse-off products is about environmental persistence in waterways, not skin safety.

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 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 PEG-type emulsifier (ethoxylated cetearyl alcohol) that helps blend the water and oil parts of a cream. CIR concluded ceteareth ingredients are safe as used, with the one caveat that they are not meant for broken or damaged skin.

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 vitamin A derivative used for the look of lines and texture. Effective but can irritate and increases sun sensitivity; usually advised against in pregnancy.

A humectant that holds water at the skin surface for a more hydrated look. No safety concern.

A chemically cross-linked form of sodium hyaluronate designed to remain on the skin surface longer and provide sustained hydration. It functions as a humectant and is well tolerated, with the same safety profile as standard hyaluronic acid.

A fat-soluble vitamin C ester that provides antioxidant activity on skin. It is more stable than free ascorbic acid and is graded low concern in published assessments, with rare reports of sensitization at high concentrations.

The most well-studied form of topical vitamin C, used as an antioxidant and to support collagen signaling and brighten uneven tone. It is acidic and can sting or irritate sensitive skin, and it oxidizes readily once a bottle is opened, which can reduce its effectiveness rather than create a safety issue.

A soothing, skin-conditioning compound (also found in comfrey root) commonly added to calm and hydrate irritated or sensitive skin. It has a long history of safe use with very low irritation potential.

An ester commonly used as a skin-conditioning agent and emollient in cosmetics. Evidence from cosmetic use indicates it is well-tolerated across skin types and helps soften and smooth the skin.

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

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 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.

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.

Pentylene glycol is a humectant and solvent that also offers mild antimicrobial support in formulas. It is generally well tolerated, with only rare reports of irritation, mostly in already sensitive or compromised skin.

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.

The sodium salt of stearic acid, used mainly to firm up stick deodorant bases and as a mild cleansing/emulsifying agent; CIR's fatty acid salts review found only minimal to mild irritation in concentrated, undiluted testing and no restriction on cosmetic use.

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

Chlorphenesin is a preservative subject to an EU maximum concentration limit and has been linked to contact dermatitis in a minority of users, particularly with repeated exposure. Most people tolerate it at the regulated use level without issue.

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.

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 small-dose synthetic antioxidant that prevents oils and fragrance in a formula from oxidizing. Not shown to pose a toxicological risk at the levels used in cosmetics.
