Niacinamide:
Melanosome transfer inhibitor that results in lighter skin.

Alpha-Arbutin:
Tyrosinase inhibitor that results in lighter skin.

SepiWhite MSH (Undecylenoyl phenylalanine):
Alpha-MSH antagonist binds MC1-R and prevents production of tyrosinase thus resulting in lighter skin.

B-white (Oligopeptide-68):
Reduces MITF (microphthalmia-associated transcription factor) to decrease constitutive and facultative pigmentation pathways. Decreases tyrosinase activity and melanin synthesis to reduce overall skin pigmentation.

K3 Vita C (Aminopropyl ascorbyl phosphate):
Stabilized form of vitamin C which has lightening properties due to the inhibition of tyrosinase. Also has regenerative and antioxidant activity.

Chromabright (Dimethylmethoxy chromanyl palmitate):
Lightening effect likely due to the inhibition of tyrosinase in a mechanism similar to that of ascorbyl palmitate.
