I love Vitamin C! The star ingredient is everywhere and does almost everything. It brightens, protects, tackles uneven skintone etc etc
Ideally you want your vitamin c product to be between 8 to 20% for effectiveness. Anything higher will risk irritation although effective but anything lower will produce unimpressive results if any
Pure Vitamin C, Ascorbic acid is what you want however it is very unstable and there are many derivatives of vitamin c available that are more stable and equally as effective
Note- it is important to reduce exposure to light and air with Vitamin C as it can make it oxidise quicker. When your vitamin C goes darker or turns brown- it is a sign of oxidation- it is no longer effective and should be thrown out! For this reason, I do not like to store Vitamin C serums for too long and I never buy backups for this reason.
Now for the fun part, PRODUCTS
I’ve tried many vitamin c serums, these are my all-time favourites. I tend to use mine in the AM for extra protection in addition to sunscreen. I will frequently update this list as I try new Vitamin C serums:
The Inkey List Vitamin C (this is high content 30% Vitamin C so I do not recommend for sensitive skin or beginners. I always mixed mine with Q10 serum also from the brand)
The Ordinary MAP- currently out of stock L
