The prime benefit of its use in cosmetic dermatology is to extend the protective ability of daily-use sunscreens against photoaging beyond their existing capabilities, which are largely inadequate to prevent premature aging.

When applied underneath broadest protection photostable sunscreens, the Skinceuticals C E Ferulic serum provides approximately eight times the skin's naturally-endowed level of protection against prematurely aging environmental factors.

More importantly, applied underneath sunscreen, Skinceuticals C E Ferulic prevents the accumulation of approximately 55% more permanent, environmentally-induced skin degradation than sunscreen alone.

For the best prognosis possible, daily sunscreen use alone is entirely inadequate in preventing the vast majority of undesirable changes in skin attributable to the cumulative effect of daily environmental exposure, namely:

• Fine lines and deep wrinkles;
• Irregular texture;
• Decreasing firmness;
• Decreasing dermal volume;
• Broken capillaries;
• Changes in colouring (such as yellowing and hyperpigmentation); and
• Skin cancer.

Skinceuticals C E Ferulic's effect is brought by its effective delivery of the skin's two major and synergistic antioxidants — lipid soluble skin-native Vitamin E, and water-soluble skin-native Vitamin C — which exist at inadequate levels within the skin irrespective of dietary factors, supplemented by the plant-native photoprotective antioxidant ferulic acid.

While a range of topical antioxidants abound to help prevent unwanted skin aging, in most instances Skinceuticals C E Ferulic remains preferable for the following key reasons:

• Used with sunscreens it ensures the highest level of reliable protection currently available — in select cases, in excess of three times more protection than even idebenone (found in Prevage, Prevage MD and Priori);
• Medical studies and practical dermatological experience which validates the formula used by patients, with repeatable, clearly measurable effects;
• Provides both lipid (fat) and aqueous (water) soluble antioxidants for comprehensive protection of skin cell membranes;
• Correct pH for dermal penetration rather than a superficial coating of the skin;
• Ideal concentration for maximum possible effectiveness and minimal potential side effects;
• Unparalleled vehicle for a formula of this type produces complete absorption, elegant cosmetic wear and excellent usability without hampering effectiveness as described;
• Amber glass packaging and glass dropper to preserve the activity of Skinceuticals C E Ferulic's otherwise unstable Vitamin C and to prevent contamination responsible for entirely counterproductive skin irritation and oxidation;
• Where use is indicated, Skinceuticals C E Ferulic is the most effective topical antioxidant formula containing ascorbic acid.

In addition to superior protection, Skinceuticals C E Ferulic delivers an ideal dose of ascorbic acid (the skin's most fundamental requirement for firmness) to the dermis, where deeper wrinkles are formed.

Newly available in 15 mL/0.5 Fl. Oz size for individuals with lesser use or a concern for maximum effectiveness in the period after opening.

Skin care products containing ascorbyl palmitate, a rendition of Vitamin C as ascorbic acid are associated with different effects and (loosely speaking) different usage profiles when compared with ascorbic acid. The two should not be considered immediately interchangeable. Refer Ascorbic Acid vs. Ascorbyl Palmitate (2008) and Ascorbic Acid vs. Ascorbyl Palmitate — The Primary Antioxidant/Firming Quandry (2007).

Please note that pH Neutral (7.07) Ascorbic Acid Alone/Primarily also fails skin.
