Homemade Vitamin C Serum - Live Simply
Pour the serum into a dark amber bottle (a funnel helps). Store the serum in the fridge for 1-2 weeks. Around the two week mark you may notice the serum's pH level change*. Your serum may have a different color and consistency, depending on the vitamin C powder and aloe used to make this recipe. My vitamin C powder is pink, but many are white.
