Hi everybody. I'm new. I've been lurking around for a couple weeks and taking in all this awesome info. I've been making the simple C serum all this time at 10%. Is it ok to do
1/2 tsp LAA
1 1/2 tsp water
1/2 tsp glycerin
to get a 20% concentration? My skin likes the c serum and I think it would respond well to a higher concentration.
Thank you for your help. I don't want to burn my face off.  |

| %age. In my thinking a 10 percent serum would be 1 part active to 9 parts water and glycerin. Is this thinking correct, or is there something I'm oversimplifying? I really would appreciate any response. |

Just a quick look at your math, it does look like that is a 20% concentration.
Here is a great tool to help you formulate - you just enter in the percentages you want of each active and it will convert to ounces, grams, etc.

20% is a rather strong vitamin C concentration. I would suggest increasing your concentration from 10 to 15% rather than jumping to 20%. |

Here are a few 10&20% recipes not mine I have them saved.
Improve your complexion on a dime:
Add 1/4 t l-ascorbic acid, 1/2 t propylene glycol (or glycerin if you have very dry skin), and 2 t distilled water to a blue or amber bottle. Shake vigorously for a few minutes, then shake a couple times an hour until the powder dissolves.
This will give you an approximately 20% solution. If you have sensitive skin, or are in doubt, cut back on the l-ascorbic acid.
I buy my ingredients from The Personal Formulator, and my bottles from Specialty Bottle; I suggest a 1/2 oz bottle with a dropper for this serum.
Homemade Vitamin C serum.
(10% concentration)
* 1/2 tsp ascorbic acid (Vit C)crystals
* 3 tsp Distilled Water
* 1 tsp Propylene Glycol or Glycerin
(20% concentration)
* 1/2 tsp ascorbic acid
* A bit more than 1.5 tsp Distilled Water
* A bit less than 1/2 tsp Propylene Glycol/Glycerin
* A small amber or dark blue glass bottle
This link to a thread here helps explain how to do the math. |

Perfect. I think I got so wound up in ingredients that I missed the calculator. Thank you for your help.
And also, I'm going to keep the 10% on my face for a bit. I've been using the formula you posted DarkMoon, and it's great so far.
you guys are great. Thanks for your patience with a Newb. |
