That's the tricky thing about them, you can't stock up because they oxidize so fast. Your DIY Vit C serum is definitely a great alternative, because it's fresher and you can actually mix up a batch everyday. I know lots of girls who do it to great effect. And thanks for the compliments on the blog, you're very kind :)Musicalhouseshttps://www.blogger.com/profile/10453401073791906028noreply@blogger.comtag:blogger.com,1999:blog-5865938336912735295.post-66716435909076819282013-07-05T14:18:17.921-07:002013-07-05T14:18:17.921-07:00I understand the part about free radicals, thanks ...I understand the part about free radicals, thanks for the explanation! Still, I wonder what's the use in buying quite large bottles of vitamin C serums when they'll stop being effective in 1-2 weeks. What do you think ? <br />This blog is great btw, I loved your post on collagen in skincare.

However, no worries about oxidized Vit C. It doesn't build up free radicals on your skin. It just won't counteract them, but it doesn't harm your skin in anyway. Vit C works by reacting with free radicals, a very useful property on your skin.Musicalhouseshttps://www.blogger.com/profile/10453401073791906028noreply@blogger.comtag:blogger.com,1999:blog-5865938336912735295.post-56334667438358911112013-06-30T03:24:52.504-07:002013-06-30T03:24:52.504-07:00I'm not sure if you are aware of this, but vit...I'm not sure if you are aware of this, but vitamin C, and L-Ascorbic Acid in particular, is no longer effective once it has oxidized. So what you're having is useless. L-Ascorbic Acid is highly unstable and it's usually fully oxidised in 1, maximum 2 weeks. Using an oxidized serum will do nothing for your skin, in fact, I read that oxidized vitamin C actually builds up free radicals Jonoreply@blogger.comtag:blogger.com,1999:blog-5865938336912735295.post-7513046875551612122013-01-31T20:50:55.247-08:002013-01-31T20:50:55.247-08:00Cosmetic Skin Solutions have a range of vitamin C ...Cosmetic Skin Solutions have a range of vitamin C serums that are very reasonably priced. Their C E serum has the exact same ingredients as the SkinCeuticals $150 one for $39. International shipping is also very reasonable.
