I was stressed about my freckles and age spots, so I searched around and decided to buy this! It contains two important ingredients in one, so I think it will be easy to manage. I will use it consistently, and if I repurchase it, I will write a detailed review.
I'm not sure if it's effective.

The brightening effect isn't immediately noticeable, but I did feel like my o
It makes my skin moisturized and brighter, so I've lost count of how many bottles I've gone through.
As I get older, I find myself reaching a phase where my face starts to look dull. Even if I get enough sleep, drink plenty of water, improve my diet, or wear gloves and a full-face cap while driving, it feels like a light has been turned off... So, I decided to put a lot more effort into whitening. I am currently using a full line of whitening products. Since I have a normal skin tone that leans towards oiliness, my "full line" is basically just a cleanser, toner, essence, and mask. Reflecting o

I purchased this because I heard it is effective for melasma. This is my second purchase, and I like the feel of it. I hope my melasma fades.
Recommended if you don't mind sticky ampoules!!
