Why does vitamin C serum turn yellow, orange or brown—and does it mean it has stopped working? 🍊

Pure vitamin C, or L-ascorbic acid, is an effective antioxidant, but it is also naturally unstable. Exposure to air, light and heat can cause oxidation, gradually changing the colour of the serum.

Oxidation may reduce potency, but colour alone cannot tell us exactly how much active vitamin C remains. A subtle change may be normal in some professionally formulated and stability-tested products, while a significant change in colour, smell or texture may be more concerning.

This is why an effective vitamin C serum is about much more than the percentage stated on the label. The form of vitamin C, pH, stability, supporting antioxidants, packaging and clinical evidence all matter.

SkinCeuticals uses dark amber bottles to help protect its antioxidant formulations from light—demonstrating why packaging is part of the formulation science, not simply part of the design.

A thoroughly enjoyable and thought-provoking visit to Windsor for SkinCeuticals Master Physician 2026.

Tina Jobburns, our Clinic Manager, and I had the opportunity to learn from leading experts in aesthetic medicine, hear about new scientific and clinical developments, and spend time with colleagues from across the profession—all accompanied by the exceptional hospitality for which SkinCeuticals is renowned.

One of the strongest messages from the conference was also one of the simplest.

When patients visit their GP, they generally expect more than a diagnosis. They expect advice and, where appropriate, a recommendation or prescription intended to improve their health and wellbeing.

Although skincare products are not medicines, the underlying professional principle is relevant: we should not leave patients to navigate skincare through guesswork, trends or advertising alone.

At Cosmedic, we want to make discussions about skincare and long-term skin health a natural part of the patient journey. That means understanding the person’s skin, concerns, lifestyle and objectives before recommending products that are suitable, purposeful and supported by evidence.

This approach is perfectly expressed through the SkinCeuticals philosophy:

PREVENT future damage.
CORRECT existing concerns.
PROTECT the skin from further damage.

We are extremely proud to work with SkinCeuticals, recognised as the world’s number one medical aesthetic skincare brand.

A special thank you to the SkinCeuticals team for a superb event, and to our Business Development Manager and good friend Laura Davis for her continued advice, friendship and support.

We returned to Cosmedic feeling inspired—and more determined than ever to help our patients and customers make informed, confident decisions about their skin.

Science. Skin. Confidence.
