Obagi Professional-C Serum 20% is a high-strength vitamin C serum designed to support a brighter, more even-looking complexion. Formulated with L-ascorbic acid and hydrating sodium hyaluronate, it works to defend the skin against everyday environmental stress while helping to soften the appearance of fine lines and uneven tone. The lightweight, fast-absorbing texture makes it especially suitable for normal to oily skin types, leaving the complexion feeling refreshed rather than greasy and promoting a smoother, more radiant look over time.

This serum fits easily into a morning skincare routine. After cleansing and toning, a few drops pressed over the face, neck and dcollet help to deliver a concentrated boost of antioxidant care before moisturiser and SPF. With consistent use, the formula helps skin appear more luminous and hydrated, supporting a healthy-looking glow that suits both simple and more advanced skincare rituals.
