I’ve made a new video about antioxidants in skincare – it’s based on this post from a while ago: Antioxidants in Skincare: What Do They Do? In the video, I talk about: What free radicals are How they’re linked to skin damage Where free radicals come from How antioxidants work Which antioxidant ingredients have been studied in clinical trials Tips on …
I’ve posted a new video on vitamin D and sun exposure. Like most skincare addicts I’ve long thought that the sun was evil and should be avoided at all costs, but it turns out that’s an outdated viewpoint! Vitamin D is important for pretty much everything in your body, and a lot of people are deficient in vitamin D. Does sunscreen …
I’ve been asked a lot for my opinion on a recent article on whether vitamin C serums are bad for your skin. In the article, Wendy explains why Oumere will never have a vitamin C serum in their line. She outlines that vitamin C can: Act as a pro-oxidant when it reacts with iron in the air (or iron and …

In my last post I reviewed some water-based vitamin C serums containing ascorbic acid (Paula’s Choice, Ultraceuticals and Ausceuticals). Today, I’m looking at some oil-based serums containing a slightly modified version of vitamin C: ascorbyl isotetrapalmitate. There are a few reasons to use a modified version of ascorbic acid (vitamin C) instead of the real thing. Since ascorbic acid isn’t …
I’ve been trying out a lot of vitamin C serums lately as long summer days and increased UV exposure looms closer. In case you’ve forgotten from my reviews of the Obagi, Indeed and Ole Henriksen serums, vitamin C is an amazing skincare multitasker.
