Glutathione
A powerful antioxidant naturally found in the body.
Popular in whitening supplements because it may inhibit melanin production, the pigment that gives skin its color.
Often paired with Vitamin C for better absorption and results.
Vitamin C
Boosts collagen production and supports skin brightening.
Enhances glutathione’s effects.
Alpha Lipoic Acid (ALA)
Another antioxidant that supports glutathione recycling in the body.
May help brighten skin tone.
Collagen
Not a whitener per se, but often added for skin elasticity and glow.
Niacinamide (Vitamin B3)
Helps reduce hyperpigmentation and evens out skin tone.
L-Cysteine
A precursor to glutathione. Supports the body in producing more of it naturally.
