What’s inside
WaterGenerally safe
The base most products are built on. It carries the other ingredients and has no safety concern.
Full ingredient details →ArbutinRestricted
Arbutin is a plant-derived brightening ingredient that is chemically related to hydroquinone and can release small amounts of it in formulation. EU regulators have set new maximum use levels for arbutin and alpha-arbutin in leave-on products because of this hydroquinone-release concern, so products sold there must stay within those caps.
Full ingredient details →1,2-HexanediolGenerally safe
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.
Full ingredient details →PropanediolGenerally safe
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.
Full ingredient details →Licorice Root ExtractWatch if sensitive
A soothing plant extract traditionally used in skincare, valued for its potential anti-inflammatory properties. Published assessments note it is generally well tolerated in cosmetic formulations, though people with sensitivities to botanicals may want to patch test.

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.
