Bought this cuz i have unsaturated lips, and this tiktok vid claimed that it can bring back the natural pink within weeks.

Here's a month after using the serum, my lips have definitely gotten pinker but not that much

Here are my lips after im more than halfway through the bottle (so i'd say 2 & a half months of usage). It's still the same amount  of pink cuz I havent been using it as regularly as before. I've also noticed only the bottom lip gets pinker as the top lip is still kinda dark.
