The Peptide Serum is a high-performance facial serum formulated by Dr. Barbara Sturm to help preserve collagen and elastin for healthier-looking, more resilient skin. Powered by a curated blend of next-generation biotech peptides, it helps visibly reduce the signs of ageing while promoting a firmer, smoother and more radiant complexion.

The advanced formula combines Acetyl Octapeptide-3, Acetyl Tetrapeptide-2, Hexapeptide-3, Decapeptide-4, Palmitoyl Pentapeptide-4 and an amino acid complex to support the skin's natural collagen and elastin production while helping protect existing collagen from degradation. Together, these ingredients help improve skin density, smooth the appearance of fine lines and wrinkles, enhance hydration and support ongoing skin renewal.

Clinically proven to help preserve up to 90% of elastin and 63% of collagen in ex vivo studies, The Peptide Serum delivers targeted care for skin that looks firmer, plumper and visibly refreshed with continued use.

Dr. Barbara Sturm approaches skincare through molecular science, formulating products to work at a cellular level where each ingredient performs a precise, targeted role within the skin. This 360° molecular approach supports repair, regeneration, and resilience across the skin’s complex structure rather than offering surface-level results. Her philosophy centres on an anti-inflammatory lifestyle, combining skincare rich in anti-inflammatory actives with a broader focus on hydration, nutrition, telomerase activation, and exosome activity to support healthy cell communication as skin ages. Every formula remains fragrance-free, paraben-free, silicone-free, and cruelty-free, ensuring compatibility with even sensitive skin.

Dr. Barbara Sturm, a German doctor and pioneering anti-inflammatory specialist, built her skincare philosophy on decades of medical research, beginning in orthopaedics where she helped develop treatments using the body’s own healing proteins. After translating this science into aesthetics, she created her PRP-based MCX facial and the bespoke MC1 cream, paving the way for her Molecular Cosmetics line in 2014. Each formula applies molecular science to target inflammation and support repair at a cellular level. Through this high-performance, science-driven approach, Dr. Barbara Sturm helps you nourish your skin, strengthen its resilience, and achieve a calmer, healthier complexion.
