Palmitoyl Tripeptide-5

INCI Name: Palmitoyl Tripeptide-5

An advanced tripeptide that helps visibly smooth wrinkles while supporting firmer, more elastic and resilient-looking skin. Palmitoyl Tripeptide-5 is an important component in the LineSync™ Peptide Complex.

Why This Ingredient Matters

Visible skin aging involves more than expression lines. Over time, changes in firmness and elasticity can make wrinkles appear more pronounced and skin look less resilient.

Palmitoyl Tripeptide-5 is a targeted cosmetic peptide developed to address these broader visible signs of aging.

Its particular strength is the combination of wrinkle smoothing with support for firmer, more elastic-looking skin, making it useful both on its own and as part of a more comprehensive peptide system.

Why Formulation Matters

Peptides aren't interchangeable.

Different peptide structures are selected for different roles within a formula.

Luzern uses Palmitoyl Tripeptide-5 where its firming and wrinkle-smoothing benefits can complement other carefully selected actives.

In Serum Absolut WE3, it works as part of the multi-peptide LineSync™ system, alongside peptides more specifically focused on expression lines.

In Eye Contour Crème, it is paired with Oxygen MFC™, Vitamin C, hyaluronic acid, caffeine and Swiss Alpine botanicals to help address wrinkles, firmness, hydration and visible fatigue around the delicate eye area.

The ingredient stays the same. What surrounds it changes what the finished formulation is designed to accomplish.

Formulation Changes Everything.

How Luzern Uses It

Palmitoyl Tripeptide-5 is one of five complementary peptides in LineSync™ Peptide Complex.

The ingredient is also used independently in other Luzern formulations, including Eye Contour Crème.

Serum Absolut WE3 — Its broader firming and wrinkle-smoothing role complements the complex's targeted expression-line peptides, helping Serum Absolut WE3 address expression lines, wrinkles, firmness, elasticity and overall skin refinement.

Eye Contour Crème — Around the eyes, Luzern pairs Palmitoyl Tripeptide-5 with Oxygen MFC™, Vitamin C, hyaluronic acid, caffeine and Swiss Alpine botanicals. Here, its firming and wrinkle-smoothing benefits contribute to a formula designed to visibly smooth crow's feet and fine lines while helping the eye area appear firmer, brighter and more refreshed.

Key Benefits

Helps visibly smooth fine lines and wrinkles

Supports firmer-looking skin

Helps improve the appearance of elasticity and resilience

Complements other targeted peptides and actives within advanced formulations

Did You Know?

The "tri" in tripeptide means that the peptide sequence is made from three amino acids. Palmitoyl Tripeptide-5 also includes a lipid component that helps make the peptide compatible with cosmetic formulations—an example of how peptide structure can be designed specifically for topical skincare.

Common Questions

What is Palmitoyl Tripeptide-5, and what does it do for skin?

Palmitoyl Tripeptide-5 is a synthetic cosmetic peptide used in advanced skincare to help improve the visible appearance of wrinkles, firmness and elasticity

Is Palmitoyl Tripeptide-5 an expression-line peptide?

Its role is broader. Unlike peptides used primarily to target the appearance of
dynamic expression lines, Palmitoyl Tripeptide-5 is particularly useful for
supporting the appearance of wrinkles, firmness and elasticity. This makes it complementary to expression-line peptides
rather than simply duplicating their role.

Why does Luzern combine Palmitoyl Tripeptide-5 with other peptides?

Different peptides can play different roles. In LineSync™, Palmitoyl Tripeptide-5 contributes broader wrinkle and firmness support while other peptides are more specifically targeted toward the appearance of expression lines. Combining complementary peptide technologies allows Luzern to address multiple visible signs of aging within a single formulation.
