Good Molecules Discoloration Correcting Serum pairs cetyl tranexamate mesylate, a tranexamic acid derivative, with 4% niacinamide in a lightweight, fragrance-free serum. The brand discloses every ingredient percentage, and the formula targets dark spots, post-acne marks and uneven tone. Creators have published trials of one week to two months, and it is a popular low-cost entry into tranexamic acid. Results are gradual and depend on consistent use with sunscreen, and the brand's pages list the derivative at both 2% and 3%.

r/Hyperpigmentation

What I did to fade my acne dark spots is by using Good Molecules' Discoloration Correcting Serum paired with their 10% niacinimide. The formulas are strong but didn't irritate my skin and I pretty much saw a big difference.
