LÉVERDELLE Peptide Serum – Anti-Aging & Skin Barrier Support

Peptides are short chains of amino acids that act as building blocks for proteins such as collagen and elastin. In skincare, certain peptides can signal the skin to support collagen production and help maintain skin firmness and elasticity. This is why peptides are widely used in anti-ageing formulations.

Peptides and retinol work differently. Retinol increases skin cell turnover, while peptides help support the skin’s structural proteins such as collagen and elastin. Because peptides are generally gentler, they are often used by people who want anti-ageing support without the irritation sometimes associated with retinoids.

Peptides are commonly used in skincare to help improve:

• skin firmness
• elasticity
• the appearance of fine lines
• overall skin texture

Some peptides may also support the skin barrier and hydration balance.

Certain signal peptides can stimulate skin cells to produce more collagen. Collagen is a structural protein responsible for skin firmness and resilience. Because collagen production naturally declines with age, peptide-based skincare is often used to help support this process.

Peptides are generally considered well tolerated and less irritating than stronger active ingredients such as retinoids or exfoliating acids. This makes peptide serums suitable for many skin types, including sensitive skin.

Peptides are commonly used alongside other skincare ingredients such as antioxidants, moisturisers and barrier-supporting creams. They are often incorporated into routines together with ingredients like vitamin C or ceramides.

Improvements in skin firmness and texture typically appear gradually with consistent use. Because collagen production is a slow biological process, visible changes may take several weeks of regular application.
