Original Body Moisturizer

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

A palm/coconut-derived fatty ester used to soften skin and help dissolve oil-soluble UV filters. It sits fairly high on lab comedogenicity scales, so some acne-prone users report clogged pores, though this does not translate into a broader safety concern for general use.

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 corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

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

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

An emulsifier made from sorbitol and isostearic acid, used to stabilize oil-in-water formulas. The Cosmetic Ingredient Review panel assessed it as safe for cosmetic use at typical concentrations.

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 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.

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 linoleic-acid-rich plant oil used as an emollient and, in some small pediatric studies, associated with support of the skin barrier when applied to infant skin. It is well tolerated with a low reported rate of contact reactions.

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.

Chamomile extract is used for its soothing and mild antioxidant reputation and is generally well tolerated. It belongs to the Asteraceae (Compositae) plant family, so people with a known ragweed or daisy-family allergy occasionally react to it and may want to patch test first.

An extract from cucumber fruit valued in skincare for its hydrating and soothing properties. It is well tolerated across skin types and commonly included in formulas designed to refresh and calm the skin.

An energizing plant extract used in skincare preparations, known for antioxidant activity in cosmetic applications. Cosmetic safety assessments generally support its use, though like many botanical ingredients it may trigger reactions in very sensitive individuals.

A warming root extract with anti-inflammatory and antioxidant properties. Some individuals report mild warming or tingling sensations; those with sensitive skin should start with lower concentrations or patch test first.

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

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

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

A fragrance fixative and solvent found naturally in balsams and used to help scents last longer. It is one of the 26 EU-designated fragrance allergens, with documented but uncommon contact sensitization.

A synthetic polymer used to impart silky texture and film-forming properties in skincare. Nylon particles remain on the surface and do not penetrate or absorb systemically, with a long history of safe use in cosmetics.

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 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.

A buffering agent used in small amounts to maintain or adjust the pH of formulas to keep them skin-friendly. It is not added as an active ingredient but to keep the product at a safe and stable pH level.

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.

Benzyl cinnamate is a fragrance ingredient found naturally in balsams and is included on the EU disclosure list of potential allergens. Reported sensitization rates are low relative to other listed allergens.

A jasmine-like fragrance compound frequently used in soaps and lotions. It is one of the 26 EU-designated fragrance allergens, though studies suggest its sensitization potency is comparatively low relative to other listed allergens.

A rose-scented fragrance ingredient found naturally in geranium and rose oil. It is one of the 26 fragrance allergens the EU requires to be labeled by name because a minority of people develop skin sensitization to it, though most users tolerate it without issue.

Benzyl salicylate is a fragrance fixative that also absorbs some UV light. It is on the EU allergen disclosure list, but the evidence suggests it sensitizes fewer people than most other listed fragrance allergens.

Amyl cinnamal is a synthetic jasmine-like fragrance material on the EU list of allergens requiring disclosure. It has shown sensitizing potential in some human and animal studies, so fragrance-sensitive users may want to check the label.

A spicy, clove-derived fragrance and flavor compound. It is one of the 26 EU-designated fragrance allergens because it can trigger contact allergy in sensitized individuals, though CIR review found it safe as typically used in cosmetics.

Methyl 2-octynoate is a violet-leaf fragrance ingredient included on the EU allergen disclosure list. Reported sensitization is uncommon and typically occurs at higher use concentrations than are found in most finished products.

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.

Retinyl palmitate is an ester of vitamin A used in moisturizers and some sunscreens for mild anti-aging and antioxidant support. Long-term panel reviews of the ingredient have generally found it safe as used, with irritation potential similar to other mild retinoids at typical cosmetic concentrations.

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.

An FDA-approved synthetic colorant commonly used in cosmetics and personal care products. A small proportion of individuals report sensitivity or allergic reactions, particularly those with existing dye sensitivities. Remains safe at approved cosmetic concentrations.

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

Natural fat molecules present in healthy skin that help reinforce the skin barrier. They are graded with no known concerns in cosmetic assessments and are well tolerated as skin conditioning agents.

A fermented extract of radish root that acts as a natural preservative and skin-conditioning agent. It has shown antimicrobial properties in formulation work and is well tolerated in rinse-off and leave-on products, though individual sensitivities can vary.

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

A widely used, gentle preservative also common in food. It is generally well tolerated, though it can occasionally cause mild, transient irritation in people with already-compromised or very reactive skin.

The sodium salt of benzoic acid, used as a preservative in both foods and cosmetics. Decades of safety review support its use at typical cosmetic concentrations, with mild irritation the main reported issue in sensitive skin.
