| I've been using Vivier's 20% serum for the last 4-5 years and have been happy with it. But just wondering whether I should try the Obagi one for a change? Thoughts would be appreciated! |

| What are the ingredients of each, the percentage of vitamin C and the pH? |

| They're both 20% but I'm afraid I don't know the pH |

| What about the ingredients? pH is very important if the products are made with the acid form of vitamin C. Ingredients wise there are those which help prevent oxidation and those which are incompatible with C. Maybe e-mail the manufacturers if you don't know the pH or ingredients? |
