The Good C Vitamin C Serum features a carefully balanced 5% vitamin C complex designed to deliver visible radiance while remaining gentle on sensitive skin. The formula contains three complementary forms of vitamin C, including oil-soluble THD vitamin C, plant-based vitamin C, and stabilised vitamin C glucoside, which work together to support a more even-looking complexion and protect skin from oxidative stress.

It contains added zinc to help improve the delivery and effectiveness of vitamin C within the skin, while aloe vera and hyaluronic acid provide lasting hydration and moisture support. With regular use, the serum helps maintain brighter-looking skin and supports natural collagen formation for a healthier, more refreshed appearance. Free from cello foil as part of ongoing sustainability efforts, The Good C Vitamin C Serum offers effective daily care with a lightweight, skin-friendly feel. It is suitable for Sturmglow, sensitive skin, and uneven skin tone.

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.
