Most neck creams on the market that are designed to firm or lift the skin are formatted with antioxidants, peptides, hyaluronic acid and polymers, but Science Serum's TIGHTNECK Clinical Anti-Aging Neck Serum introduces something new with a "smart polymer" known as a poloxamer.
This poloxamer can be found in what the brand calls its SmartGel, which is designed to respond to the heat of one's body. The neck serum is meant to be applied thickly to the neck and upper chest area and left to sit for about five minutes. During this time, the serum is said to become very thick and tight as it reaches body temperature. After this period, it can be wiped away entirely with a damp cloth.
Aside from its TIGHTNECK product, Science Serum notes that the only other item on the market that features SmartGel is its TIGHTEYE treatment.
