What the gurus are saying

This serum divides experts on whether its form of vitamin C actually works. At seven percent concentration, it earns praise for affordability and accessibility, with some gurus finding it delivers visible benefits when layered into a routine. However, others note that 3-O ethyl ascorbic acid hasn't been shown to penetrate skin or convert to the more proven L-ascorbic acid form, and some people develop allergies to it. Best patch-tested first if you have sensitive skin.

"I would personally recommend the Boots Vitamin C Serum. This comes in at a seven percent concentration of a stabilized form of pure vitamin C. That seven percent concentration is going to give you really good results. That's a robust concentration of vitamin C but it's not sky high, so you're not going to get a whole lot of side effects and sensitivity, especially because this is formulated with some hydrating and calming and soothing ingredients too."

"When seeking out vitamin C serums, [...] the more coveted form you're hoping for is L-ascorbic acid, but it's very challenging to formulate in a way that remains stable and gets into the skin. Three-O ethyl ascorbic acid may help act as an antioxidant, so it's not a bad ingredient, [...] but it hasn't been shown to actually get into the skin and convert to ascorbic acid. People do develop allergy to it."

"The Boots Vitamin C and the hyaluronic acid line, the sleep mask, the hydrator, and the serum have been amazing. Specifically, the little serums from Boots. I like to mix them and I can apply them in layers. That has worked really well for my skin this year, especially since I've been trying out the vitamin C recently and I really really like it on my skin. [...] Boots is making skincare accessible and affordable and inexpensive and at Target. Like everything is under 10."
