Hadalabo Shirojyun Premium Whitening Lotion

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

Tranexamic acid is used topically at low concentrations to help even the look of dark spots and redness-related discoloration. It has an extensive systemic safety record as an oral medicine, and topical skin absorption is minimal, though a dedicated cosmetic-specific safety review has not yet been published by the main cosmetic safety panels.

Another stable phosphate ester of vitamin C, chosen by formulators for its water solubility and gentleness compared to pure ascorbic acid. Available safety data and long history of use in leave-on products show a low rate of irritation.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

A broken-down form of hyaluronic acid with smaller molecules intended to penetrate more deeply into the skin. It functions as a humectant and is well tolerated, with the same safety profile as standard hyaluronic acid.

A humectant that holds water at the skin surface for a more hydrated look. 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 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 that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

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 widely used emulsifier and solubilizer that has been in cosmetics and pharmaceuticals for decades. The CIR has assessed it as safe with no known concerns at typical cosmetic concentrations. As with any surfactant, some people with very sensitive skin may experience mild irritation.

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