Night Serum Day 3

Recipe: 200 grams or 7.05 ounces

Test 4

Test 5

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. 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 4
In Test 4 we decreased the water, increased the Cyclomethicone, increased the Hydrovance, and decreased the Conditioning Emulsifier as compared with Test 1. This formula was more fluid, much more transparent (because of the decrease in Conditioning Emulsifier), and had a creamy feeling with a long-lasting massage time.

Test 5
In Test 5 we increased the Dimethicone, increased the Hydrovance, decreased the Isopropyl Myristate, and decreased the Conditioning Emulsifier as compared with Test 1. This formula was more fluid, much more transparent, had a decrease in the velvety feeling, but took longer to rub in than Test 4.
