About OBAGI - C® Fx Clarifying Serum

Brighten, Even, and Renew Naturally

Potent Skin Brightening Without Hydroquinone for a Healthier Glow

Reveal a more luminous and even-toned complexion with Obagi-C® Fx Clarifying Serum — a powerful, hydroquinone-free brightening solution designed to visibly reduce dark spots, melasma, and discolouration. This advanced antioxidant serum is infused with 10% L-Ascorbic Acid (Vitamin C) and Arbutin, a natural skin-lightening agent that works to correct uneven skin tone while protecting against environmental stressors. Ideal for those seeking a gentler alternative to traditional brightening treatments, Obagi-C® Fx Clarifying Serum helps refine skin clarity, texture, and radiance over time.

    10% L-Ascorbic Acid helps neutralise free radicals, boost collagen production, and improve overall skin tone.

Frequently Asked Questions

What is the difference between Obagi-C Fx and Obagi-C Rx Clarifying Serum?
Obagi-C Fx uses arbutin as its brightening agent and is available without a prescription. Obagi-C Rx contains 4% hydroquinone and requires a prescription. Fx is a gentler, long-term option; Rx is typically recommended for more stubborn pigmentation under clinical supervision.
Is Obagi-C Fx Clarifying Serum suitable for sensitive skin?
Yes — the hydroquinone-free formula with arbutin is well-tolerated by most skin types, including sensitive skin. It is designed for safe, long-term daily use.
Can I use this serum morning and night?
It is recommended for morning use. Apply after cleansing and toning, then follow with moisturiser and broad-spectrum SPF. Your skincare professional may advise on evening use.
How long does it take to see results?
With consistent daily use, most users notice visible improvements in skin tone and brightness within 4–8 weeks. Continued improvement develops over 8–12 weeks.
Do I need a prescription for Obagi-C Fx Clarifying Serum?
No — unlike the Rx version, Obagi-C Fx is a non-prescription formula available for purchase without a clinical consultation.
