Vegan BHA & Matcha Ampoule

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 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 beta hydroxy acid used to smooth texture and clear pores. Safe at cosmetic levels; can be mildly irritating if overused.

A cross-linked polymer used to thicken formulas and create lightweight gel textures. The large molecular weight prevents penetration into the skin and is not absorbed; well tolerated in cosmetics.

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.

An extract from neem tree leaves, valued for antioxidant and skin-conditioning benefits in formulations. Well tolerated overall, though isolated cases of contact sensitivity have been reported in the literature.

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 mild plant-derived emulsifier combining polyglycerol and lauric acid. Used in gentle formulas to blend oil and water phases; well tolerated across skin types at cosmetic concentrations.

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 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.

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

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 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 salt derived from citric acid that buffers pH and prevents metal oxidation in formulas. Widely used in food and cosmetics, it is well tolerated 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.

An extract from neem tree flowers, used for its antioxidant and conditioning properties. While neem has traditional use in skincare, rare cases of contact sensitization have been noted in literature; most people tolerate it without issue.

A starch breakdown product used as a thickener and texture modifier in cosmetic formulations. It is well established in cosmetics and food applications with documented low irritation and contact sensitization risk across diverse skin types.

A rich, solid-at-room-temperature butter extracted from cocoa seeds, valued for its intense emollient and conditioning properties. While generally well tolerated, it carries a higher likelihood of comedogenicity, so people with acne-prone skin may want to opt for lighter alternatives.

A small peptide bonded to copper that supports collagen remodeling and skin repair. Studied in cosmetics and dermatology for decades with a strong safety record at cosmetic-use levels.

A signal peptide designed to inhibit neurotransmitter release and reduce facial muscle tension, marketed as a gentler alternative to botulinum toxin. Cosmetic-grade formulations show no significant systemic absorption at recommended levels and are well tolerated in product use.

A five-amino-acid peptide lipid that stimulates collagen and elastin synthesis. One of the most established peptides in cosmetics with decades of safe use and no reported sensitization issues.

A signal peptide attached to palmitic acid that activates collagen synthesis in skin cells. Well tolerated across skin types with no significant safety concerns in cosmetic use.

A signal peptide designed to modulate muscle contraction and reduce the appearance of expression lines without systemic effects. Cosmetic formulations are well tolerated, with published assessments confirming safety at recommended concentrations.

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.

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.
