Open Formula - aruneka review for Vitamin C Solution

Very watery lightweight texture without any smell. 🤔 my thoughts: It has 15% of l-ascorbic acid,which is high percentage. Previously i have only used the 5% of vitamin c serum. When i received the serum ot was already slight yellowish. I used this at my morning routine. Using this for almost 1 month and i saw the results. It has brighten overall my skin tone. But it didn’t saw any drastic results on my dark spots. May b i need to use more for that. Overall a good vitamin C serum that works.
