The stinky "hot dog water" smell is the ferulic acid, not the ascorbic acid (the vitamin C). Skinceuticals was one of the pioneers that realized that adding the ferulic to lower the solution pH allowed the (notoriously unstable) ascorbic acid to better penetrate the skin and not degrade so quickly. It allows the C to better penetrate skin and I make my own vitamin c serum and it's so worth it! Much cheaper than buying a serum, you can control the percentage and add oils and stuff if you fancy. Besides that, it's always fresh (Vitamin c is not very stable, so better make it fresh). It just takes me a few minutes and it lasts me for about 2 weeks without going bad.

How to make the Serum: Step 1: blend all the distilled water and the Vit C powder in the bowl by way of whisking. Step 2: add in 15ml of the glycerin and stir once again. Step 3: add in the remainder of the glycerin and stir thoroughly until the mixture is complete.

And since it contains hyaluronic acid, it'll leave the skin's hydration levels nice and healthy in This is the reason the SkinCeuticals C E Ferulic Serum formulation is superior, and why it’s worth the price tag! In C E Ferulic, the brand has developed a stable formulation that contains 15 per cent L-ascorbic acid at pH 3.2. Plus, it includes other synergistic antioxidants (ferulic acid and vitamin E) that enhance vitamin C’s Both brands are owned by L'Oréal. The Sephora Vitamin C Serum contains Ascorbyl Glucoside, a non-acidic, non-active derivative of Vitamin C (Ascorbic Acid) as one of the very last ingredients, so what's burning your skin is likely not the "Vitamin C," it's the fragrance and fragrance adjacent irritating ingredients.
