Obagi-C RX C-Clarifying Serum Normal to Dry | Prescription Hydroquinone and Vitamin C Serum

The prescription brightening serum for normal to dry skin in the Obagi-C RX programme. Where the non-prescription Obagi-C FX C-Clarifying Serum uses Arbutin, the RX C-Clarifying Serum uses prescription-strength 4% hydroquinone combined with 10% L-Ascorbic Acid for significantly faster and more complete results in patients with significant melasma, persistent sun damage and treatment-resistant hyperpigmentation. Prescription only, dispensed following clinical consultation.

The combination of hydroquinone 4% for direct melanin production inhibition and L-Ascorbic Acid for antioxidant protection against UV-triggered melanocyte stimulation provides a dual-mechanism brightening approach that produces results cosmeceutical brightening serums cannot match for significant pigmentation.

This is a prescription-only product. A clinical consultation is required. The clinic will be in touch to confirm suitability before dispensing.

Who Is It For?

• Normal to dry skin with significant melasma, sun spots and treatment-resistant hyperpigmentation requiring prescription hydroquinone
• Those on the complete Obagi-C RX Starter System for normal to dry skin

How Does It Work?

Hydroquinone 4% inhibits tyrosinase at prescription potency, significantly reducing new melanin synthesis. L-Ascorbic Acid 10% inhibits UV-triggered melanocyte activation, supports collagen synthesis and provides antioxidant protection. Together they address both the production of new pigment and the environmental triggers that maintain it. Formulated for normal to dry skin penetration and comfort.
