Noticeable glow
This serum has transformed my dull skin. After a few weeks of use, my skin looks brighter and more radiant. It's a bit pricey but worth it for the results.

Good but tingles
I definitely see a difference in my skin's texture and tone. The tingling is a bit strong at first but goes away. It's thick and absorbs well. Great for anti-aging.

Game changer
I've tried many vitamin C serums and this is by far the best. It's potent yet gentle. My fine lines have softened and my skin feels firmer. Love the texture and how it layers under moisturizer.

Took time to work
It's effective but you need patience. I didn't see results until about a month in. It's also a bit sticky on the skin. But my complexion does look more even.

Worth the splurge
This serum is amazing. It's high concentration but doesn't irritate my sensitive skin. My skin looks plump and youthful. I've repurchased multiple times.

Solid vitamin C
This is a concentrated formula that works. I noticed improved brightness in about two weeks. The only downside is the scent—smells a bit like hot dog water. But it fades quickly.

Caused breakouts
Unfortunately, this broke me out. My skin is sensitive and this was too strong for me. The texture is nice, but I can't use it.

Great for evening tone
I've been using this for three months and my dark spots have faded significantly. It's a bit sticky but I don't mind. Good value for the concentration.
