skinken review for 10% Niacinamide Booster

My expectations for this puny 20ml bottles were very high. After a month of consistent use, I would say this is definitely worth it if you wanna splurge. It was easily the moist well rounded formulation here. It delivers on hydration, brightening, oil and breakout control all while being non-tacky and easily layered. You really do get what you pay for here.
