Tomatoes Detoxifying Charcoal Paper Mask

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

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 plant extract used for mild astringent and soothing effects. Evidence for its benefits comes mostly from traditional use and small studies rather than large trials, and the tannins it contains can be mildly irritating for some people, particularly in older distilled formulas that retain trace alcohol.

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

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 sugar alcohol that draws water into the skin. It is well tolerated and widely used in skincare and food. Not known to cause concern at the concentrations used in cosmetics.

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.

Green tea extract is a well-studied topical antioxidant with a long history of use in serums and moisturizers, generally well tolerated at cosmetic concentrations. Panel safety reviews of Camellia sinensis-derived ingredients have not identified meaningful topical hazard.

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.

Galactoarabinan is a polysaccharide pulled from larch tree wood, used to form a light, breathable film that helps skin hold onto moisture and gives serums and primers better spreadability. It was reviewed by CIR as part of a larger group of plant polysaccharide gums, where reproductive and developmental toxicity data across the group came back essentially negative, and it was found safe as used.

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 natural polysaccharide derived from brown seaweed, used as a thickener and gelling agent in cosmetics. It has a strong safety history in topical formulations and is well tolerated across skin types.

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.

Bisabolol is a botanically derived (or synthetically nature-identical) compound used for its calming, anti-irritant reputation in sensitive-skin formulas. Safety reviews and long clinical use have found it well tolerated with a low rate of reported reactions.

A salt form of glycyrrhizic acid, a compound from licorice root prized for soothing irritated skin. It is well tolerated at cosmetic levels and has a long history of use in skincare formulations.

A preservative derived from caprylic acid (coconut-sourced) with antimicrobial activity that supports formula stability. Available data support its use at cosmetic concentrations.

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

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.

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 naturally occurring acid used to preserve and adjust pH in cosmetic formulas. It is generally recognized as safe at cosmetic use levels, with mild irritation possible on broken or very sensitive skin at higher concentrations.

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.

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

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.

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

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.
