Rice Water Bright Vegan Serum

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 light, low-odor glycol used as a solvent and humectant, extremely common in Korean toners and essences. It has a low reported irritation rate and is graded low concern in published assessments.

A smooth synthetic emollient ester used to soften skin and carry oil-soluble ingredients. It is well tolerated and graded low concern in published assessments.

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

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 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 soothing humectant that helps skin and hair look conditioned. Very well tolerated.

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 silicone-based powder used to improve texture and slip in formulas. It is lightweight, absorbs excess moisture, and provides smooth application. Well studied in cosmetics with no skin safety concerns.

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 buffering agent used in tiny amounts to set a product's pH, most often alongside gel-forming polymers. It is graded low concern in published assessments at the levels used.

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

A crosslinked acrylic polymer that thickens and stabilizes formulations. Published assessments show it to be well tolerated at cosmetic use levels, with no evidence of penetration into viable skin layers or systemic absorption.

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.

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.

A disaccharide sugar that acts as a humectant, drawing moisture into the skin and helping prevent dryness. It is well tolerated and commonly found in skincare formulas designed to support skin barrier health.

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.

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 light, linoleic-acid-rich oil extracted from grape seeds, traditionally used for skin conditioning. It is generally well tolerated, though botanical sensitivity and rare allergic reactions are possible, especially for those with grape allergies.

A synthetic gelling and stabilizing polymer that gives lotions and gels their smooth, cushiony texture. The large molecule stays on the skin surface rather than penetrating, and it is graded low concern in published assessments.

A polysaccharide produced by fermentation of fungal cultures, used to thicken and stabilize formulas. It is well tolerated in cosmetics and often chosen by natural-leaning brands. It functions similarly to other gelling agents but comes from a more controlled fermentation source.

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 fermentation-derived polysaccharide used to thicken and hydrate formulas. It absorbs and holds water in the skin, contributing to a smooth texture. Limited clinical data but no known sensitizers or safety concerns at cosmetic use levels.

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

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.
