Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
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.
