Skinceuticals® has gained a tremendous following among skincare professionals for a number of products backed by extensive scientific research and studies, and particularly for its C E Ferulic®, which is often referred to as the gold standard in Vitamin C serums.
SkinCeuticals C E Ferulic® Combination Antioxidant Treatment comes complete with a number of of anti-aging claims, but the ones you can bank on with this product (based on a significant amount of research) are its abilities to reduce free radicals and to defend skin against oxidative stress, as well as improving multiple signs of aging. It contains 15% ascorbic acid, a form of vitamin C considered an excellent antioxidant and an anti-inflammatory agent (Experimental Dermatology, 2003 and Bioelectrochemistry & Bioenergetics, 1999).
The lightweight liquid formula of this product is fragrance free and suitable for all skin types (including acne prone). Those with rosacea or very sensitive skin may wish to proceed with caution, as such potent concentrations of ascorbic acid can be potentially sensitizing—a patch test for a few days will determine how your skin will respond to this formula.
15% ascorbic acid, when used on a regular basis and in conjunction with a broad-spectrum sunscreen, can make a significant improvement in the appearance of sun damage, uneven skin tone and strengthen the skin’s barrier. Vitamin C can also help boost the free-radical protection ability of your sunscreen when worn underneath (Skin Research & Technology, 2008 and The Journal of Pathology, 2007).
This product’s pH of 3 is good news for you, as ascorbic acid is stable only in low-pH formulations (Dermatologic Surgery, 2001). In addition, present in this water-based antioxidant serum are vitamin E and ferulic acid. Vitamin E, appearing here as alpha tocopherol, also has a well-established reputation as an effective antioxidant.
Ferulic acid is relatively new to the skin-care scene, but earlier research suggests that it provides antioxidant and sun-protective benefits to skin while enhancing the stability of topical applications of vitamin E (International Journal of Pharmaceutics, 2000 and Anticancer Research, 1999).
C E Ferulic® Combination Antioxidant Treatment earns the highest expert rating for the fact that it is a potent, well-formulated treatment that doesn’t include needless problematic ingredients.
