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.
Vitamin C (ascorbic acid) is a water-soluble antioxidant that neutralizes free radicals, supports collagen synthesis, and inhibits melanin production to brighten skin and even tone. It is commonly used in serums at concentrations of 5-20% and works synergistically with vitamin E and ferulic acid.
