Dipotassium (commonly seen as dipotassium phosphate or dipotassium glycyrrhizate) is typically used in skincare formulations as a pH adjuster, buffering agent, or chelating/stabilizing component. It helps maintain product stability and skin-compatible acidity rather than acting as a primary treatment active.

Contact allergy / sensitization | Very rare | Rarely reported allergic contact dermatitis; uncommon for buffering salts. |

Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
