Name: Obagi Medical Professional-C Serum 10% (1 oz.)
SKU: 57966
Availability: InStock

If you’ve been looking for a vitamin C serum that’s effective and gentle, this one might be your match.

Obagi’s Professional-C Serum 10% uses pure L-ascorbic acid to help brighten skin tone, smooth texture, and soften fine lines—without irritating sensitive or rosacea-prone skin. It has a silky, lightweight feel that absorbs quickly and plays nicely with the rest of your routine (no pilling here).

Users love how quickly it delivers a healthy glow and how well it layers under SPF and makeup.

Note: To get the most out of your vitamin C serum, apply it right after cleansing and let it absorb for a minute before layering on moisturizer or SPF. And always keep the bottle tightly sealed—L-ascorbic acid is powerful, but it’s sensitive to air and light.

💡 good to know

This is a great “starter” vitamin C serum for those with reactive or delicate skin, especially if stronger formulations have been too much in the past. It’s part of Obagi’s dermatologist-backed lineup, and many fans say it helped their skin look noticeably brighter and smoother in just a few weeks. The packaging isn’t perfect, but the formula inside gets high marks across the board.
