Frequently asked questions
Which Obagi vitamin C serum should I start with?
Which Obagi vitamin C serum should I start with?
Match the percentage to your experience. New to vitamin C or with reactive skin, start with Professional-C Serum 10%, step up to 15% once settled, and reserve the Professional-C Serum 20% for oilier, resilient skin that wants maximum antioxidant strength. Apply it every morning after cleansing, before moisturiser and SPF.
How do I layer Professional-C Serum in my routine?
How do I layer Professional-C Serum in my routine?
Use it every morning: cleanse, press 4-5 drops onto dry skin, wait 60 seconds, then follow with moisturiser and a broad-spectrum SPF. Vitamin C plus daily sunscreen is the pairing that delivers the visible brightening and antioxidant defence. Store the bottle away from direct light so the L-ascorbic acid stays potent.
What's the difference between Professional-C and the Obagi-C Fx serums?
What's the difference between Professional-C and the Obagi-C Fx serums?
Professional-C is pure L-ascorbic acid focused on antioxidant defence and radiance. The Obagi-C Fx C-Clarifying Serum pairs vitamin C with arbutin to target the look of dark spots and uneven tone, the C-Therapy Night Cream continues that brightening overnight, and the Fx Exfoliating Day Lotion buffs away the look of dullness by day. Run Professional-C in the morning and bring in the Fx pieces where pigmentation is your main concern.
How often should I use the Professional-C Polish + Mask?
How often should I use the Professional-C Polish + Mask?
Use it two or three mornings a week in place of your normal cleanser. Massage it over damp skin for the 30% vitamin C micro-polish, then leave it on for three minutes as a brightening mask before rinsing. Follow with your Professional-C serum for an extra-radiant finish.
Will a 20% vitamin C serum irritate sensitive skin?
Will a 20% vitamin C serum irritate sensitive skin?
High-strength L-ascorbic acid can sting or flush reactive skin. Begin with Professional-C Serum 10% every other morning, build to daily, then progress up the strengths only once your skin is comfortable.
