What Are Peptides and Why Do They Work?
Peptides are the foundation of high-performance anti-ageing skincare. These short chains of amino acids are the building blocks of collagen, elastin and keratin, the proteins responsible for your skin’s firmness, elasticity and smooth texture. As we age, natural peptide production slows, accelerating the formation of fine lines, wrinkles and loss of definition.
Dr Sebagh’s peptide formulas go beyond the ordinary. Each product in this collection is developed with clinically-substantiated peptide complexes, including Palmitoyl Pentapeptide-4, Micro-Molecular Collagen Peptides and Dr Sebagh’s proprietary BioPeptide ETF, formulated at concentrations that deliver measurable results. No filler. No compromise. Just science that works.
From the clinics of London’s Chandos House to your daily routine, these are the formulas Dr Sebagh trusts with the skin of his most discerning patients.

Frequently asked questions
Q: What are peptides in skincare?
A: Peptides are short chains of amino acids that act as messengers in the skin, signalling cells to produce more collagen, elastin and hyaluronic acid. In skincare, peptides are used as active ingredients to reduce fine lines, firm skin and accelerate repair. Unlike retinol, peptides work without irritation, making them suitable for all skin types.
Q: What do peptides do for your skin?
A: Peptides stimulate the skin’s natural collagen synthesis, helping to restore firmness and smooth the appearance of wrinkles. Certain peptides, such as Palmitoyl Pentapeptide-4, have been shown to reduce the depth of fine lines measurably within weeks of use. Others help strengthen the skin barrier, improve moisture retention and accelerate post-treatment recovery.
Q: Which Dr Sebagh products contain peptides?
A: Several Dr Sebagh formulas are built around clinically-active peptide complexes: Serum Repair contains Palmitoyl Pentapeptide-4 and Micro-Molecular Collagen Peptide for deep hydration and wrinkle reduction; Supreme Maintenance Youth Serum features three specialised anti-ageing peptides to stimulate, repair and strengthen the collagen matrix; and Crème Vital harnesses the BioPeptide ETF to prevent premature ageing. All are available in this collection.
Q: Are peptides better than retinol?
A: Peptides and retinol work differently but are highly complementary. Retinol accelerates cell turnover but can cause sensitivity; peptides build collagen and firm skin without irritation. For sensitive or mature skin, or anyone undergoing cosmetic treatments, peptides are often the preferred choice. Used together, they can deliver enhanced anti-ageing results, as practised at the Dr Sebagh clinic.
