Azelaic acid is a naturally occurring dicarboxylic acid used topically to treat acne and rosacea, working through antibacterial, anti-inflammatory, and comedolytic actions. It also inhibits tyrosinase, helping reduce hyperpigmentation.
Tranexamic acid is a synthetic lysine derivative used topically to reduce hyperpigmentation, melasma, and post-inflammatory dark spots by inhibiting the plasminogen-plasmin pathway and reducing melanin transfer to keratinocytes. It is also valued for helping calm redness and improve uneven skin tone.
