Mix rose water and glycerine, and in a small glass or ceramic bowl until combined.
Add the Vitamin C powder and mix it well with a wooden spoon until the Vitamin C is dissolved.
Now add argan and vitamin e oil and mix everything properly.
Pour the mixture into a dark-colored glass dropper bottle using a funnel and again shake the bottle for 1 minute. It is important to use colored glass because Vitamin C oxidizes fast!
Store the serum in the fridge for 1 week. This serum has a shorter shelf life because the Vitamin C oxidizes in the water over time. So, try to use the batch within 1 week.
It can be applied morning and night after cleansing the face.
How To Apply
Apply it on your cleansed face twice a day.
Don’t forget to apply sunscreen before going out in the sun.
Notes
You might find it tingles when applied, this is normal. If it burns, then make a weaker dilution(like use ¼ teaspoon or ⅛ teaspoon vitamin C powder). Do not apply this serum if its color has changed, it happens due to the oxidation process of vitamin C. Always do a patch test.
