Rich Moist Soothing 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 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 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 used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

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.

An ester that combines cetyl alcohol with ethylhexanoic acid, serving as an emollient. It softens skin and is well tolerated in cosmetics.

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.

Technically a liquid wax ester rather than a true oil, jojoba closely resembles skin's own sebum and absorbs without feeling greasy. It is well tolerated across skin types, including acne-prone skin, with no significant irritation or comedogenicity signal in the available data.

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 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 humectant naturally derived from sugar beets that helps skin draw in and hold water; it has a long history of safe use with no meaningful irritation or sensitization concerns.

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.

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

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.

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 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.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A polysaccharide extracted from yeast cell walls or oat bran. Used for hydration and skin conditioning, beta-glucan is well tolerated with emerging evidence for supporting skin barrier function. No safety concerns flagged in cosmetic use.

A phospholipid emulsifier from soy or sunflower that binds water and oil and helps other ingredients absorb. It is a natural component of skin membranes, well tolerated, and reviewed as safe as used; a soy-derived grade is not a meaningful concern for a soy food allergy because the protein is largely absent.

A plant extract used in Korean skincare for its soothing, antioxidant reputation. It is well tolerated with a low reported irritation rate; the soothing claims rest on limited but reasonable evidence.

A glycol used very widely in Korean and Western skincare as a lightweight humectant, solvent, and gentle preservative-booster, often in place of traditional preservatives. It has a low reported irritation rate at use levels and is graded low concern in published assessments.

A plant extract long used in traditional wound care and now common in "cica" soothing products, valued for calming redness and supporting the skin barrier. It is generally well tolerated, with rare contact allergy reported.

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

A lab-made version of a lipid naturally found in the outer skin barrier. It is added to creams and cleansers to help replace lipids that washing can strip away, and it is not linked to irritation or safety concerns.

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 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.

This is a stable, water-soluble derivative of vitamin C that converts to ascorbic acid in skin and is used for antioxidant and brightening support. It is generally better tolerated than plain ascorbic acid and has a low reported rate of irritation in formulation testing.

A saturated fatty acid found in palm oil and naturally in the skin, used as an emollient to soften and condition skin. It is one of the most studied fatty acids and is well tolerated.

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.

Lavender essential oil naturally contains linalool, geraniol, and coumarin, several of the recognized fragrance allergen constituents, so it can trigger contact reactions in fragrance-sensitive users even though it is a "natural" ingredient. It is not a general hazard for most people, but those with a known fragrance allergy should treat it like any other essential oil.
