What is Peptinexia™ Expression Serum?
Peptinexia™ Expression Serum is a targeted facial serum designed for customers primarily concerned with the appearance of dynamic expression lines. The formula combines 2% SNAP-8 and 1% Syn-Ake with 0.5% GHK-Cu, 5% niacinamide, 1% ectoin, and 1% hyaluronic acid in a lightweight hydrating serum base.
Why Use It?
Repeated facial movement can make lines around the forehead, brows, eyes, and mouth appear more noticeable over time. Peptinexia™ Expression Serum uses two cosmetic peptides selected specifically for expression-line care, supported by ingredients that help maintain hydration, barrier function, visible firmness, and skin comfort.
Expression-Line Peptides
SNAP-8 2%, also known as acetyl octapeptide-3, is a cosmetic peptide developed for formulations addressing the visible effects of repeated facial movement. Syn-Ake 1%, identified by the INCI name dipeptide diaminobutyroyl benzylamide diacetate, is a synthetic peptide used in expression-line skincare. Together, they provide two complementary peptide approaches within one targeted serum.
Supporting Actives
GHK-Cu 0.5% supports the serum’s broader focus on skin conditioning, visible firmness, and extracellular matrix signaling. Niacinamide 5% helps support the skin barrier, improve uneven-looking tone, and reduce moisture loss. Ectoin 1% supports hydration and helps protect against environmental stress. Hyaluronic Acid 1% attracts and retains moisture, helping the skin appear plumper, smoother, and more supple.
Hydrating and Conditioning Base
In addition to 1% hyaluronic acid, the serum base includes glycerin, panthenol, aloe, rosehip, cucumber, chamomile, and rice extracts. Together, these ingredients help replenish moisture, calm the appearance of dryness, and leave the skin feeling soft and comfortable.
Suggested Use
Apply one to two pumps to clean skin once daily, either morning or evening. Concentrate application on areas where expression lines are most visible, including the forehead, between the brows, around the eyes, and around the mouth. Gently smooth over the skin and allow the serum to absorb before applying moisturizer or sunscreen. Avoid direct contact with the eyes.
Airless Packaging
Peptinexia™ Expression Serum is supplied in a 15 mL airless pump bottle. The sealed dispensing system helps preserve the peptide-rich formula by limiting exposure to oxygen, environmental contaminants, and repeated contact during use.
