    Our Approach to Innovation

    At Obagi, breakthrough innovation begins with a deep understanding of skin biology. Knowing how the skin works at the cellular level enables us to systematically approach every opportunity to make a positive impact and support healthy, optimal performance. Developing transformational products with unparalleled results requires both a relentless focus on the essential skin proteins that diminish with aging as well as attention to those proteins that accumulate and prevent otherwise healthy skin from looking youthful. Our approach ensures our skincare advances work in multi-faceted ways to support skin health.

    Our Process

    Our rigorous product development process leaves no stone left unturned. No detail is too small when it comes to product formulation. The Obagi R&D team pours over thousands of ingredients to find the most efficacious ones, then reviews each and every form of these ingredients to identify the highest quality, most bio-available form. They don’t stop there: the team works further to optimize key ingredient concentrations as well as pH to be confident Obagi products can deliver our promise for results you can see and feel.

      FAQ

      What does vitamin C serum do for your face?

      Vitamin C serum is a popular skincare product known for its numerous benefits for the face. Vitamin C, or ascorbic acid, is a powerful antioxidant that helps protect the skin from environmental damage caused by free radicals, such as UV rays and pollution. When applied topically, vitamin C promotes collagen production, which enhances skin elasticity and reduces the appearance of fine lines and wrinkles. It also brightens the skin by inhibiting melanin production, making it effective in fading hyperpigmentation, dark spots, and acne scars. Additionally, vitamin C has anti-inflammatory properties, making it useful for calming redness and irritation. Overall, vitamin C serum helps improve skin texture, tone, and radiance, making it a valuable addition to anti-aging and skincare routines.

      Is it OK to use vitamin C serum everyday?

      It is generally safe to use vitamin C serum every day, especially if the serum is formulated for daily use and suits your skin type. However, it's essential to introduce it into your skincare routine gradually, especially if you have sensitive skin. Start with a lower concentration of vitamin C and observe how your skin reacts. If no irritation occurs, you can gradually increase the frequency and concentration. Also, it's crucial to wear sunscreen during the day when using vitamin C serum because vitamin C can make the skin more sensitive to sunlight. Daily use of vitamin C serum, combined with proper sun protection, can provide the best results in terms of improving skin tone, reducing hyperpigmentation, and promoting overall skin health. If you have any concerns about using vitamin C serum, consult a dermatologist for personalized advice.

      Why is my Professional-C Vitamin C serum darker in color than what appears on site?

      Obagi Vitamin C Serums may vary in color from clear to deep amber upon manufacture due to the nature of the natural antioxidant. This variation is normal and does not impact the product’s effectiveness.
