Vitamin C Ester 20% Dark Spot Corrective Serum

What it is

This targeted serum is built around vitamin C derivatives for the look of brighter, more even-toned skin. Perricone MD positions it as a dark spot corrective serum for daily use as part of a brightening routine.

Key ingredients

• 3-O-ethyl ascorbic acid: A stable vitamin C derivative included to help support brightening goals.
• Alpha-arbutin: A well-known brightening ingredient that helps target the look of uneven tone.
• Ferulic acid: Included as an antioxidant partner to help support the formula’s vitamin C performance.
• Tetrahexyldecyl ascorbate: A lipid-soluble vitamin C form used in skin-brightening formulas.

How to use

Use the serum as the targeted treatment step in a daily routine, applying it to the skin where a more even-looking tone is desired. Perricone MD presents it as a focused brightening serum, not as a single-step replacement for broader sun protection or routine steps.

Who should be careful

The ingredient list includes fragrance/parfum, limonene, linalool, and citral, so fragrance-sensitive skin may want to patch test before regular use. This is general ingredient information, not medical advice.

What the brand claims

Perricone MD describes the serum as a dark spot corrective formula for more even-looking skin and a visibly brighter complexion. The brand names vitamin C derivatives and brightening ingredients as the core actives in the formula.
