Japanese Sake Lotion

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

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 basic amino acid naturally found in skin that draws moisture into the stratum corneum. It is well tolerated in cosmetics at typical concentrations and has been used safely in skincare formulations for decades.

An amino acid widely used in cosmetics for skin conditioning and moisture retention. It is well-studied and well-tolerated across skin types at cosmetic use levels.

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.

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

A synthetic polymer used to form a water-resistant film and keep chemical UV filters evenly suspended in sunscreen lotions. It is not absorbed through skin and CIR has not flagged it as a safety concern in cosmetic use.

A salt form of glycyrrhizic acid, a compound from licorice root prized for soothing irritated skin. It is well tolerated at cosmetic levels and has a long history of use in skincare formulations.

Retinyl palmitate is an ester of vitamin A used in moisturizers and some sunscreens for mild anti-aging and antioxidant support. Long-term panel reviews of the ingredient have generally found it safe as used, with irritation potential similar to other mild retinoids at typical cosmetic concentrations.

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 higher-molecular-weight polyethylene glycol ester of hydrogenated castor oil, used as an emulsifier in creams, serums, and other formulations. Like other PEG-modified ingredients, published cosmetic safety assessments grade it as safe in rinse-off and leave-on products.

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

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.

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

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

A preservative that keeps products free of mold and bacteria. Reviewed repeatedly and considered safe at the low levels used.

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.
