Chronic exposure to sunlight causes the generation of oxidative stress in the skin, resulting in impaired mechanical and biophysical properties of the skin.

Clinical symptoms include:

• fine lines and wrinkles;
• pigmentary changes (hyperpigmentation, hypopigmentation);
• loss of skin elasticity and firmness.

Antioxidants have been shown to reduce the negative effects of UV damage by counteracting the generation of oxidative stress in the skin.

A clinical trial of twenty-four weeks was conducted to evaluate the efficacy and tolerance of a topical antioxidant composition (Skinceuticals C E Ferulic) containing vitamin C, E, and ferulic acid.

Clinical Skinceuticals C E Ferulic Results:

• Clinical assessments: fine lines, skin texture (uneveness), firmness (degradation of elasticity) and smoothness (roughness)
• Bio-instrumental results over time (to 24 weeks of use): uneven pigmentation (hyperpigmentation) and elasticity degradation.

May be ordered with any Skinceuticals Antioxidant Serum:

• Skinceuticals Eye Gel AOX+
