About

A mood-stabilizing pharmaceutical compound used in psychiatric medicine that has no established cosmetic use but may appear in some hair treatment products.

Lithium Carbonate is an inorganic salt used primarily as a psychiatric medication for bipolar disorder (mood stabilization) and depression. Its cosmetic use is highly unusual and not supported by established safety data for topical application. Systemic lithium absorption is well-documented to cause significant adverse effects including thyroid dysfunction and renal impairment, making any dermal absorption from cosmetics a serious concern. Lithium compounds are not listed in EU cosmetic positive lists, indicating no established safe use in cosmetic formulations.

Known concerns

  • No cosmetic safety assessment available
  • Systemic toxicity from lithium is well documented
  • Thyroid and renal effects from systemic exposure
  • Not approved for cosmetic use
