Bright Diary - witchedhazel review for Acne Serum

I usually call it cap for skincare that promises glow up in such short time, but this brand have this "7 days guarantee or money back" so i'm intrigued. And wow i still can't believe this serum helps so much with my acne. When i first started using it i have an irritated pimple and a really stubborn blackhead, today is my 7th day and they're gone, only leaving a bit of PIH but its okay i have tons of brightening skincare
