Because preserved Vitamin C is oxidized Vitamin C.
The moment Vitamin C oxidizes, it stops inhibiting melanin and starts promoting it. Our L-ascorbic acid is fresh, unoxidized, and delivered directly to your skin before it degrades. No derivative form. No ascorbyl phosphate compromise.
Because your dark spots have a copper problem.
Tyrosinase the enzyme that manufactures melanin requires copper to function. Anacardic acid from fresh cashewnuts chelates that copper. Remove the cofactor, interrupt the reaction, halt the pigmentation. Ayurveda understood cashew's power centuries before biochemistry named the mechanism.
Because exfoliation should be enzymatic, not chemical.
Fresh avocado proteases dissolve the dead keratin layer that sits atop your skin, along with the melanin-loaded cells within it. These are self-limiting enzymes they stop when the dead skin is gone, unlike acids that continue reacting with living tissue.
Because salmon oil carries astaxanthin
a carotenoid antioxidant 6,000 times more potent than Vitamin C at neutralizing reactive oxygen species. Oxidative stress triggers melanin as a defence. Quench the stress, and the trigger disappears.
Because rosemary contains carnosic acid
a self-regenerating antioxidant. It sacrifices itself to neutralise a free radical, then reforms to do it again. Most antioxidants are spent in one reaction. Rosemary keeps working.
