Because it is cheaper and better (the Vitamin C powder is more active, fresher and free of preservatives!). The costs are about $1.25 for 2 weeks (or $2.50 if you use rosewater).
The only con is that you will have to do a new batch every 2-3 weeks as we don´t use preservatives and the Vitamin C serum will expire sooner. But it really is not much work to do a new batch! It will take you 1 minute every 2 weeks, I promise!
What you need:
Ascorbic Acid Powder and distilled water- or rosewater if you like to be fancy. If you have dry skin, you might consider adding also Glycerin.
I personally use rosewater as this smells fabulous and is already distilled.
Because this DIY Vitamin C serum is so much more active, you might find that 20 % is too much to handle (it can almost sting a little bit which I have never experienced with a store bought item)- so you might want to start with a 10 % Vitamin C serum and depending on your skin´s tolerance move your way up over a couple of weeks to the desired 20 %.
For a 10 % Vitamin C serum you need:
10% Vitamin C serum for dry skin:
For a 20 % Vitamin C serum you need:
20 % Vitamin C serum for dry skin:
Fill it into a spray bottle (don´t use a clear one!) and shake it real good! You can store it in the fridge to leave it longer fresh. If the nozzle gets clogged from the Vitamin C crystals- just run the nozzle under hot water.
That´s it! So easy and so effective! Enjoy!
Spray every morning onto your face, neck and don´t forget the back of your hands too (against those age spots!)
