Which ingredients make this serum a good fit for skin with dark spots?
3-O-Ethyl Ascorbic Acid and Niacinamide make this serum a great fit because they help brighten and even your skin tone. Lactic acid and Palmitoyl Pentapeptide-4 further help smooth the skin and boost radiance.
What does Vitamin C do for skin with dark spots?
Vitamin C helps fade dark spots and brightens uneven skin. It works by slowing down pigment production and boosting overall skin clarity.
What does Palmitoyl Pentapeptide-4 do for skin with dark spots?
Palmitoyl Pentapeptide-4 is primarily used to smooth wrinkles and fine lines, and it is unlikely to directly reduce dark spots on its own. Skin with dark spots typically needs brightening ingredients like vitamin C, niacinamide, or alpha arbutin to safely fade discoloration and even out skin tone.
