What is Palmitoyl Pentapeptide-4?
Palmitoyl Pentapeptide-4 is a white powder with a purity of 98%. It is used in skincare products for its anti-aging properties. As we age, our bodies lose protein and water content, leading to a range of symptoms such as wrinkles and loss of skin elasticity. Palmitoyl Pentapeptide-4 can help alleviate these issues.
How Does Palmitoyl Pentapeptide-4 Work?
It stimulates our body’s own fibroblasts to produce beneficial collagen, fibronectin, and glycosaminoglycans. The synthesis of these molecules plays a crucial role in maintaining skin firmness.

Palmitoyl Pentapeptide-4's most notable feature is its anti-aging properties, primarily manifested in the following
- Its small molecule makes it easily absorbed by the body.
- It penetrates the dermis, promoting the proliferation of collagen. The more collagen our bodies contain, the more elastic our skin becomes.
- It maintains and increases the skin’s moisture content, making it more hydrated.
- It increases the thickness of our skin, creating an additional barrier between our skin and the outside world.
Applications of Palmitoyl Pentapeptide-4
As an anti-aging ingredient, it compensates for the slow growth of our own cells. Adding it to everyday skincare products can accelerate cell proliferation and lock in moisture. It is currently widely used in skincare products and healing medications.


Palmitoyl Pentapeptide-4 VS Retinol
There are some differences in how these two ingredients are used. Products containing Palmitoyl Pentapeptide-4 require fewer precautions, as it’s considered mild and non-irritating. However, products containing Retinol are most important to avoid using in the dark. Furthermore, it’s important to control the amount and frequency of use during initial use, as this can cause an allergic reaction.
