We all want to have fabulous skin, but skin serums can run expensive! And you want to have high quality ingredients that you put on your skin rather than fillers and other ingredients that dont do much. Thats why I like to make my own serums! DMAE is an amazing anti aging ingredient that combats sagging and wrinkles.  Vitamin C is a fabulous anti oxidant and brightener. Hyaluronic acid helps keep moisture in your skin and smooth wrinkles.  All these ingredients help with with collagen production.  You can make your own in smaller batches so you know its fresh and potent.
here is the recipe: Hyaluronic Acid may only be mixed with cold water, but it is important to note that it should never be dissolved in room temperature, warm, or hot water. It must be mixed in cold water only. It is not easily soluble in this cold water, but there are directions for making an easily consumable supplement here.
First measure out 12 fl oz of the distilled water. Pour into water bottle, seal, and refrigerate for at least 4 hours.Using the thermometer, make sure that the water has reached a temperature at or below 39 degrees Fahrenheit.Pour the Hyaluronic Acid powder on top of the cold water, seal the lid, and shake vigorously for a few seconds. Do not expect the Hyaluronic Acid powder to dissolve. It does not dissolve in cold water and doing this will cause clumps to form. This is what is supposed to happen.Put the Hyaluronic Acid powder and cold water in the refrigerator once more, but do not allow the solution to freeze. Once the Hyaluronic Acid powder has been in the refrigerator for about 4 to 8 hours, the powder will begin to disperse throughout the water. Given up to 12 or 24 hours, the Hyaluronic Acid will have dissolved completely into the water and the viscosity of the resulting liquid will be somewhat similar to honey or synthetic maple syrup, however it should still pour out easily. You may now consume the solution. For purposes of internal use, the yield of actual Hyaluronic Acid per tablespoon of this mixture is about 150mg.
