Obagi Professional-C Serum 20%

As an esthetician, I often always use and recommend a vitamin C serum, and Obagi Professional-C® Serum 20% is great for clients seeking a potent, high-concentration of vitamin C to combat aging, brighten the complexion, and protect against environmental damage. This serum is formulated with L-ascorbic acid, the most effective form of vitamin C, which penetrates deep into the skin to neutralize free radicals, boost collagen production, and reduce the appearance of fine lines and hyperpigmentation.

With its 20% concentration, this serum is ideal for clients with normal to oily skin who are looking for maximum antioxidant protection. The high potency makes it particularly effective at improving skin tone and texture, and many clients report a brighter, more youthful appearance after consistent use. Despite its strength, the serum is lightweight and absorbs quickly, making it easy to incorporate into a daily routine. It layers well under moisturizers, sunscreen, and make-up.
