Syn®-Coll: (INCI: Palmitoyl Tripeptide-5, Glycerine) It’s used at 1% to 3% in the aqueous phase – it can handle heat up to 80˚C so you can use it in the heated phase – to stimulate collagen synthesis and increase skin firming while moisturizing. It may reduce the appearance of wrinkles and stretch marks.
It’s also recommended to add it to the cool down phase after emulsion, but I’ve had success with the heated water phase two.
We met this ingredient in a previous duplication, Potential duplication of ASDM Beverly Hills Ultra Firming Cream (part one), and Natalie Skiller’s The Neck’s Best Thing formula!
