View product ↗Description
This facial serum from Good Molecules combines 3% tranexamic acid and 4% niacinamide to address discoloration concerns at the source. The formula is designed to target dark spots, sun spots, and acne marks for a more even skin tone, while supporting overall skin health. The lightweight texture sinks in cleanly under moisturizers and SPF, making it easy to layer into both AM and PM routines. Free from fragrance, alcohol, mineral oils, and ethoxylated ingredients, it's suitable for all skin types — particularly combination/oily — and is pH-balanced at 5.5.
Warnings
