| I love a good night serum for the face. We are going to do a 3-day study of this serum formula. We will be using the same ingredients each day, but we will change the percentages of the ingredients to see how the opacity, thickness, and so forth changes.Today we are doing 2 formulations. The first one (Test 1) I am using as a baseline in which I compare all of the other formulations to. I chose what I found to be an interesting combination of ingredients. Cyclomethicone is known for its ability to dry quickly and spread onto the skin easily. Dimethicone adds a nice glide to lotion and leaves the skin velvety. Isopropyl Myristate helps to reduce greasiness. I chose Conditioning Emulsifier because it adds to that nice velvety skin feel and since I am using a limited amount of oils in this recipe, I did not need a really strong emulsifier.
Hydrovance is a great product to use instead of Glycerin. It helps your lotion soak in fast without a greasy feeling and it is heavenly. I tried Hydrovance the first time I made a hand cream and it was amazing how moisturized my hands were but with no grease. Orchid Extract is a great choice for a night serum because of its skin friendly properties. Squalane was chosen for its lubricating properties and it helps reduce greasiness. Finally, I chose Vitamin E Natural because it is also a great night serum product with all of the antioxidant power!

Instructions
Weigh out water, Cyclomethicone, Dimethicone, Hydrovance, Isopropyl Myristate, and Conditioning Emulsifier in your microwave safe container. Microwave in short burst until Conditioning Emulsifier is melted. I found that stirring with a spoon in between your 15-20 second bursts really helps the water to not get over heated and explode in the microwave. The smaller the batch you make, the shorter microwave bursts you will want with more frequent stirring. I might have had a little accident the first time I weighed out my ingredients. I might have also had Conditioning Emulsifier pieces get all over the inside of the microwave after the water got over heated and caused the explosion. Whoops!Blend mixture with an immersion blender well. Allow to cool. Weigh the additives into your cooled serum. Stir well and squeeze into bottles! I used the 1 oz LDPE bottles with a disk top closure because I prefer squeezing my face lotions and serums. You can also use our PET jars.
Test 1
I felt that this was the thickest and heaviest of all of the formulas. It had a really nice velvety feeling on the skin. For me personally, this one was not my favorite. I have combination skin and it is the summer so I prefer lighter more fluid lotions on my face in the summer. I might choose this one during the winter when it is dry and cold though.
Test 2
This formula had more Cyclomethicone, less Dimethicone, more Hydrovance, less Isopropyl Myristate, and less Conditioning Emulsifier than the original one. It still felt velvety but that extra Hydrovance helped it soak in quicker on the face and the overall serum was more transparent.
