I love this vitamin C serum, it’s easy to make & saves so much on purchasing products that have many unwanted ingredients. First I buy pure vegetable glycerin (food grade) then after eating orange or lemon I grate the peeling and let them dry on a coffee filter, then I add it to the glycerin, Then add 2% vitamin E.
You can make small batches at a time or save the shavings in a sealed container & make a bigger batch. The measurements are not exact but I use 1/4-3/4 of grated fruit to approx 1 1/2 cup glycerin. shake the container as often as you think about it over the next 2 weeks, then you can strain through a coffee filter the grated fruit & discard, this step is optional. (But leaving behind fruit can make it rancid) . That’s the finished product, I use it as a lip gloss, add it to my bath, mix it to make other natural products. The best use of this is an aid in wrinkles, glycerin attracts moisture. Apply some to your face after washing Pat dry with a towel & apply the serum. I use it under my eyes & above my lips to help reduce fine lines.
Keep large batches in the refrigerator. Enjoy!
