Skincare Guide - Peptides
Peptides – signaling agents for firmer, regenerated skin
Peptides are short chains of amino acids that act as messenger substances in the skin and have diverse functions. They can stimulate processes such as collagen and elastin production, improve skin structure, and activate regenerative mechanisms.
How peptides work
The blog of [ Schönheitsberatung.de (2024) ] explains that peptides are found in skincare products and can have a positive effect on skin condition, as they support the skin barrier.
An article on [ Aesthetico.de (2024) ] describes how “anti-aging peptides” can reduce wrinkles and slow down the breakdown of collagen fibers.
Types of peptides and their functions
- Signal peptides: Stimulate fibroblasts to produce collagen and elastin.
- Carrier/transport peptides: Transport minerals such as copper, important for cell and tissue repair.
- Neuro-peptides: They influence facial muscles and can reduce wrinkles caused by facial expressions.
- Enzyme-inhibiting peptides: Slow down the degradation of structural proteins such as collagen.
Peptides and skin aging
As we age, the body's own collagen production decreases. Peptides target this process. According to [ Eucerin Germany (2025) ], peptides can be used in creams to combat the first signs of skin aging and have a moisturizing effect.
Skincare with peptides – what is important?
Effectiveness depends on molecule size, penetration capacity, and formulation. As the source on Aesthetico.de states: "Although peptides show promise, their effectiveness depends on their composition and application."
Peptides at NATURFACTOR®
The Porcelain Skin Serum product from NATURFACTOR® contains selected peptide chains that specifically support the skin structure and contribute to regeneration – ideal for a smoother and firmer complexion.
Who is it suitable for?
Peptides are suitable for all skin types, but are particularly relevant for mature skin, skin in need of regeneration or skin stressed by environmental factors – also as a preventative measure for younger skin.
Conclusion
Peptides are a key class of active ingredients in modern skincare. They activate cellular processes, promote structure and regeneration, and have a visible and well-tolerated effect. In formulations like the Porcelain Skin Serum from NATURFACTOR®, they unfold their effects effectively and luxuriously.
