Potent 20% L-ascorbic acid serum to brighten skin tone, support collagen production and defend against environmental stressors for normal-oily skin.
Enhance skin radiance with Obagi’s best‑selling Professional‑C Serum 20%, formulated with a 20% concentration of L‑ascorbic acid – gold‑standard form of vitamin C. This strong yet gentle face serum is designed to help reduce visible signs of ageing and hyperpigmentation while supporting a brighter, more even complexion.
Vitamin C is a powerful antioxidant that helps protect against free radical damage caused by everyday exposure, from blue light emitted by digital devices to environmental pollutants. In its L‑ascorbic acid form, it penetrates effectively into the skin to deliver benefits where they are most needed.
It also plays a vital role in collagen production, helping to improve firmness, elasticity and overall skin plumpness. To further enhance hydration, the Professional‑C Serum contains sodium hyaluronate, a derivative of hyaluronic acid capable of holding up to 1000 times its weight in water.
This supports long‑lasting moisture retention, prevents dryness and encourages a smoother, rejuvenated complexion. Available in three strengths of L‑ascorbic acid, the Obagi Professional‑C Serums provide tailored formulations for different skin types.
The 20% concentration is ideal for normal to oily skin, offering advanced antioxidant protection and visible results.
