Vitamin X Serum.

"It's a little bit darker than I'd prefer, but that tells me I need to start using this one fast because 55 bucks is a little bit more expensive than the other vitamin C serums I discussed. It is a little bit greasy. It does have a little bit of a tendency to stain skin, so it's a little bit more high maintenance. So you want to make sure if you use this to follow up with sunscreen everywhere. Otherwise, you will start to notice an orange halo around your face, which isn't the most attractive look I've ever seen."

"In here we've got 15% ascorbic acid, we've got Resveratrol, we got silymarin which is another great antioxidant also known as milk thistle, we've got ferulic acid and we also have EGCG which is another great ingredient for your skin. So this stuff is really nice, although I will say the more I use this the older it gets, it starts to kind of leave orangish spots on my face. When it's fresh it's fine, but when it's older it starts to, if I don't cover it up with moisturizer, it starts to get kind of an orange halo around my face."

"It's the Regimen Lab Vitamin X Serum, which is 55 bucks, so it's one of the more expensive products but it's really great anti-aging product all the way around. You'd want to use this during the daytime because it contains ascorbic acid, it also contains acetyl Ginger and then it also contains Resveratrol. It's got vitamin E, ferulic acid and CoQ10, it's also got some other nice ingredients in here like EGCG and chromanol, all that good stuff, so it's a really nice serum. But you got to be careful around the corners of your face because if it dries too much it can end up making you look a little orange around the corners, so you got to make sure to blend it in really well with your skin. That's a really nice option for anti-aging."

"Their Vitamin X Serum is great. This is their level serum for brightening skin. It's really nice."

"I love their level serum, their Vitamin X Serum is great"

"This is my most recent bottle of it, I think it's my third bottle of it. It's 55 bucks and it contains trans-resveratrol, it's also got sorbic acid in it, salicylic acid, and then also ferulic acid in this one. It's really nice actually. The one thing I do notice is the very first bottle I went through I didn't notice it, the second bottle I started to notice it more. If you don't take a little bit of extra time to blend it you'll start to notice orange around your face and it's not necessarily a fun look, so especially if you use bronzer or anything like that. But it's nice because it's got a lot of good antioxidants in it, so if you're looking for something with some nice ingredients in it for a morning product this one's also really nice. pH is three, it's got EGCG, vitamin E, resveratrol, azelaic acid."
