Peptide Cica Hyalshot

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

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

A water-soluble humectant that holds moisture and gives essences a soft feel. 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 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 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 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 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.

An ester of palmitic acid and ethylhexanol, commonly used as an emollient and skin-conditioning agent. It is well studied and well tolerated in cosmetics.

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

An olive-oil-derived emulsifier, almost always paired with cetearyl olivate, that holds water and oil together and leaves a light skin-like finish. It is well tolerated and graded low concern in published assessments.

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.

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 naturally occurring nucleoside used in anti-aging formulas, often marketed for smoothing the look of fine lines. It has a low irritation profile and no established hazard at cosmetic use levels.

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 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 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.

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

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

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 triterpenoid from Centella asiatica associated in published studies with skin resilience and wound-healing support. It is generally well tolerated in cosmetic concentrations.

A triterpenoid from Centella asiatica with published research linking it to skin barrier function and calming effects. It appears well tolerated at cosmetic levels.

A purified triterpene from Centella asiatica (the "cica" plant) used in soothing and barrier-support products, especially Korean formulas. It is well tolerated with a low reported irritation rate; the strong repair and anti-aging claims around it are more marketing than settled evidence.

A key active compound from Centella asiatica linked in published research to skin barrier support and soothing properties. It is well tolerated in skincare formulations.
