This is the best Vitamin C serum I've ever used. Application is tricky due its watery texture. For that reason, I've tried other brands but not only were they more expensive, they did not prove as effective. After a few fails, I went back to Suzie's Vita C Serum. It has quality ingredients and is fairly priced. It is effective, meaning results for me seem to be the best brand. I don't use all Suzie's skin care. My Suzie's product favs are Vitamin C, Skin Brightening Serum which a tiny drop mixed into the C makes it an easier application; 24K Serum, and Almond Serum. I don't use any of the jar products because I don't like skin care in a jar...love tube and pump packaging skin care only.

One of my favorites. I use it daily.

The texture of the serum was surprising to me. This serum is about the same consistency as water. It is a good product but I think a thicker consistency would make application easier. It's hard to make sure there is an even layer everywhere and I'm not sure exactly how much is getting on my face and how much is on my hand.
The brightening effect of the Vitamin-C seems to be high quality I just wish the consistency was thicker.
