Peptides are organic chemical compounds formed by the assembly of amino acid molecules into chains via a peptide bond.
Peptides - function in the skin
Peptides became popular in cosmetic products due to their bioactive properties. They are able to interact with skin cells by multiple mechanisms, present high potency at low doses.
Their small size ensures penetration into the deeper layers of the skin and has a directional effect.
In the skin, peptides are involved in many physiological processes:
- stimulate collagen production,
- effectively bind water molecules inside the skin and therefore help maintain optimal skin hydration,
- stimulate the skin to regenerate and rebuild,
- brighten discolorations by reducing the production of melanin,
- They have a lifting effect on the skin by increasing skin tone.
How can peptides used in cosmetics be divided?
Many peptides are known in cosmetics. They can be divided into 3 basic groups based on biological activity:
Signal peptides
They influence processes occurring inside cells. In this way, they influence the activity of fibroblasts to produce skin support fibers - collagen and elastin.
Transport Peptides
These act as transporters of active substances deep into the skin, e.g. copper ions which are essential in the wound healing process.
Relaxing Peptides Neuropeptides
Their most important task is to reduce wrinkles. They have a botox-like effect, i.e. they relax facial muscles. The result is a softer facial expression and a reduction in wrinkles.
Cosmetics with peptides - when should we use them?
Cosmetics with peptides should be included in the care of all types of mature skin. Skin creams are especially recommended for people who have noticed the first signs of ageing on their skin. It is worth using them regularly. Noticeable effects are usually visible after a few weeks. They should be used regularly min. 4-5 weeks.
Peptides - with which active ingredients should they be used?
Peptide creams should not be combined in a single application with cosmetics with acids. Due to the low pH of products with acids, peptides can change their properties and lose their biological activity. If you do not want to abandon the cream with an acid at night, use a cream with peptides for the day, and with an acid at night.
Peptides work very well with retinol and ceramides. The combination of these active ingredients will bring many benefits to the skin. The skin will be rejuvenated, supple and firm. Apply the cream with peptides on the cleansed skin and wait about 30 minutes. Then apply a retinol cream.
Peptides are called non-invasive botox. They guarantee an effective anti-wrinkle effect. Their regular use quickly improves the quality, density, hydration and firmness of the skin, prevents accelerated aging.

Peptide day cream - The cream is designed for daily care of any type of skin in need of lifting. The cream formula contains 30% of lifting and firming ingredients.
Peptide night cream - The cream is based on the action of the complex of three peptides, which stimulates the synthesis of different types of collagen. It makes the skin smoother and softer.
Peptide eye cream - Designed for the delicate eye area. Restores a fresh look to the eye area. The skin around the eyes is tightened, firm and wrinkles are reduced.
Retinol - the combination of two forms of Retinol gives younger-looking skin that is free from imperfections; wrinkles are smoothed and skin tone is unified and even.
