Perricone MD Vitamin C Ester CCC+ Ferulic Brightening Complex 20%, 2 fl. oz.

This is a premium facial serum formulated for advanced brightening, tone-evening and skin texture improvement. According to the brand, it uses their proprietary Vitamin C Ester plus two additional forms of vitamin C — reaching a total concentration of 20% — along with ferulic acid and vitamin E. 
It is designed to penetrate deeply (via a phospholipid delivery system) for maximal benefit. 

Key Benefits

• Helps brighten skin, diminish dark spots/discoloration, and even skin tone. 

• Firms and smooths skin texture, giving the appearance of “collagen-rich” skin according to brand claims.

• Protects against free radical damage through ferulic acid (an antioxidant) and vitamin E. 

• Suitable for all skin types (normal, dry, oily, combination) though those with sensitive skin may wish to patch test. 

Key Ingredients & Features

• Vitamin C Ester (for example, 3-O-Ethyl Ascorbic Acid & Tetrahexyldecyl Ascorbate) — fat-soluble, stable forms of vitamin C designed for deep penetration. Ferulic Acid — supports and stabilizes vitamins C & E, enhances antioxidant protection. 

• Vitamin E (Tocopheryl Acetate, etc.) — nourishment + antioxidant benefit. 

• Delivery system: a phospholipid based system that claims deeper penetration into skin layers.

• Texture: described as a lightweight serum, citrus-scented. 

How to Use

• After cleansing, apply the serum to face and neck using gentle upward motions. Wait until fully absorbed. 

• Use morning and evening for optimal results. (If using in the morning, follow with broad-spectrum sunscreen.) 

• Because this is a treatment serum (not just basic moisturizer), layering with your normal moisturizer afterward is recommended.
