Vitamin C Boosting Serum.

"This serum is one of the most brightening serums I have ever used. It will help to brighten your skin, fade post-acne marks, dark spots, and discoloration. This is also going to help with fine lines and help stimulate new collagen as well. There are ceramides in here and hyaluronic acid, so great ingredients to hydrate the skin and to keep your skin barrier nice and strong. The consistency of this is very thin like water. It's not sticky or greasy. It doesn't pill with skin care. You could use this twice a day, but I just use this in my morning skin care routine. This would be the first serum that I would pick up."

"It is truly 10 out of 10."

"This is the vitamin C boosting serum. I've been using this since late summer, early fall of last year. This is my third bottle, and I have a fourth bottle all ready to go once this is finished. This has been one of my go-to vitamin C's as of late, and I've been using this for over 6 months. I think this is one of the best vitamin C formulations on the market. This is a vitamin C derivative formulation. Vitamin C is a great ingredient to brighten the skin, fade discoloration, and protect the skin from pollution. Besides the vitamin C in here, there are other amazing ingredients like niacinamide, tranexamic acid, and alpha arbutin. These three are tyrosinase inhibitors which help to block the overproduction of pigment in the skin. I love how those three ingredients are in here along with the ethyl ascorbic acid vitamin C derivative."

"This is the Dr. Althea Vitamin C Boosting Serum. It's very impressive and very brightening. So if you are struggling with that uneven skin tone or let's say you have a dull complexion, this actually does work and it works pretty quickly, especially if you're using this twice a day. When I first started using this, I did have a few post acne marks on my cheeks, and I thought, let's use this twice a day and let's see how quickly this can perform and fade those post acne marks. And I would say within a week and a half, almost 2 weeks, those post acne marks were pretty much diminished. I found this so brightening and gentle. It's also hydrating. And I also believe that this does a really good job to help with texture, keeping the skin super soft and smooth. This does contain a vitamin C derivative. There's also tranexamic acid in here, alpha arbutin, which are great ingredients to also brighten the skin. And I like how thin and lightweight this is. I do have another one in my bathroom already going."
