thanks Minda. So what exactly are the measurements? the Vit c powder & water?
Depends on the concentration you're looking to make and exactly how much you want to make.
For sure, my measurement unit in making these toners are teaspoons. I like to just make toners instead of serums with simple water for its cost effectiveness and ability for me to tell if my solution has oxidized/gone bad.
I put my solutions into a tinted 1oz amber glass bottle so my solutions are small and fresh. For a 15% solution, I usually make a mix of .5 LAA powder and 2.5 teaspoons of water making the entire solution consist of 3 teaspoons. This gives me a concentration of 16% and it's just right for me right now until I move up to 20% soon.
This amount fills up about half my bottle which lasts me a week.
If you want an easy way to calculate the necessary amounts, simply get a percent calculator and play around with the amounts!
Assuming you are new to vitamin c topical use, a 5% solution would require 1 teaspoon of LAA and 20 teaspoons of water. That's quite a lot so to go for a much smaller amount, a 5% concentration would require .5 teaspoon of LAA and 10 teaspoons of water. Much more reasonable. Different amounts, same concentration!
Wherever you store your vitamin c, make sure it's in an airtight container that blocks out light. Keep your solution out of light and oxygen. It should last a week before you need more unless you add preservatives to make it last a little longer like vitamin e or ferulic acid.
Because 5% is quite weak, it may take a little longer for effective results. But I saw amazing results in only a month when I started out at a measly 10% so I won't say fantastic progress at that concentration is impossible.
