Pour the hydrosol or water into a glass jar, and place in a double broiler. Heat on low until liquid is around body temperature.
Remove from heat and add all other ingredients to the liquid, and mix thoroughly.
The lecithin might look like it is not going to mix, just let it sit for a few hours and shake ever so often and it will eventually mix in.
Once the mixture has cooled down to room temperature, pour into a flip-top bottle.
To use, moisten a cotton pad and gently wipe over the skin of the face, and avoid your eyes.
