Frequently Asked Questions

What is the difference between Obagi Professional-C 10%, 15%, and 20%?

The three concentrations suit different skin types and tolerances. 10% is ideal for sensitive, dry, or first-time Vitamin C users. 15% suits normal to combination skin with some Vitamin C experience. 20% is the most potent and best suited to oily or resilient skin types seeking maximum brightening results.

When should I apply Obagi Professional-C Serum?

Apply in the morning to clean, dry skin before moisturiser and SPF. Vitamin C works synergistically with sunscreen to provide enhanced antioxidant protection throughout the day.

How long does it take to see results?

Most users notice improvements in skin brightness and tone within 4–6 weeks of consistent daily use. Fine line reduction and firming effects typically develop over 8–12 weeks.

Is Obagi Professional-C Serum 10% suitable for sensitive skin?

Yes — the 10% concentration is specifically recommended for sensitive, dry, or Vitamin C-naïve skin. It delivers effective brightening with a lower risk of irritation compared to higher concentrations.

Can I use this serum with other actives like retinol or niacinamide?

Yes — Vitamin C can be layered with niacinamide and used in the same routine as retinol (applied at different times of day). Apply Vitamin C in the morning and retinol in the evening for best results.
