Lift Active C10.

"This product costs £45. The positives are nothing. The negatives are that it's got 12% ascorbic acid, which is a worst for skin of color. The fourth ingredient in here is denatured alcohol. That's why you're getting a very quick dry feel. Denatured alcohol leads to premature aging because it generates free radicals in the skin, the exact opposite of what the vitamin C is trying to do. So this is ridiculous. They also add in fragrance and that's what that beautiful smell is. If something's smelling lovely, it's a problem for our skin because 3 to 4% of the population gets contact dermatitis from fragrance. And for skin of color that can lead to hyperpigmentation. My entire channel is dedicated to skin of color, so I'm always going to err on the side of caution. Because if you think about it, we get about a million views a day. So for me, 3 to 4% of the population watching my channel, that's tens of thousands of people getting contact dermatitis from a product. So for me, this product is a disaster."

"This is a vitamin C serum. If you are somebody with acne prone skin and you want to use vitamin C serum, this is a great one because it has those anti-aging benefits of vitamin C and antioxidants, which increase potency of your sunscreen, but also helps with post acne marks and active breakouts. It's a super lightweight, fast absorbing serum with 10% pure vitamin C. It gently refines skin texture and brightens without being greasy. It also contains a little bit of salicylic acid for that mild exfoliation. And it does smell really nice. The key ingredients here are 12% ascorbic acid, salicylic acid, and niacinamide."

"It's another hybrid very fragrant hybrid serum cream. My feeling is that if you're going to do it, it does have a very summery citrusy feel, which is very nice in terms of its fragrance and appearance, but in my opinion you're either a serum or you're a cream. We understand the principle behind having hybrids, you get that spread, but you again cancel out the benefits. Sometimes you want to wear a vitamin C and then put a moisturizer on top, and you're denying people that option. It's very silicone to me. You've got ascorbic acid as a very high concentration, glycerin which is great, then you've got denat alcohol which is a big no-no nowadays. There's no excuse for that to be so high up. Silicone, like I said, I think it's a lot of silicone in these products, and if you layer them up, silicone can be comedogenic. I know it's not listed as a comedogenic agent, but it is. It's also terrible for the environment. You've got the salicylic acid, which combination of salicylic acid and vitamin C is nice because exfoliating allows the vitamin C to penetrate nicely. There's some good peptides in there. These are the type of ingredients I expected with their retinol serums. So it's got a lot of good active ingredients, I think that's pretty cool. But overall it's disappointing."

"This one by La Roche Posay has 10% L ascorbic acid in it, which is the active form, but the problem with that form for many people is it can be irritating and just be hard to tolerate, so if you have really sensitive skin or rosacea-prone skin or very dry skin, that's something to take into account. Other key ingredients in this include salicylic acid, so it's also going to help exfoliate the skin at the same time. The packaging is in that dropper bottle format, and for me personally I don't love dropper bottle formats for vitamin C because you are going to be exposing it to air every time you open and close it, and that means it's going to break down and go bad more quickly. So if you choose a vitamin C serum in a dropper bottle, you should be using this very often in your routine and using it up quickly, but if you are somebody who is only going to want to use your vitamin C a little bit more sparingly, you probably are going to want to find one that is packaged differently. This product costs $46.99."

"La Roche Posay is another L'Oreal brand, but I believe their product has fragrance in it, which can be irritating and can actually worsen hyperpigmentation. Still, this is a good brand. The packaging is a dropper bottle, and as the ascorbic acid is exposed to air each time you go in and out of it, it is more likely to degrade, so ideally airless pumps would be a better option."
