C Eye Serum Advance+

Vitamin C, eye-calibrated

Most vitamin C serums carry an avoid-the-eye-area warning; this one is built the other way around. Ascorbic acid third in the formula travels with hyaluronic acid at second, the hydration cushion that makes a genuine C dose wearable on the face’s thinnest skin, brightening the look of shadowed under-eyes and supporting the collagen that thin skin leans on.

The capillary angle

Much under-eye darkness is vasculature showing through thin skin. Bioflavonoids, the citrus-derived compounds long studied for capillary resilience, and zinc sulfate address that side, while the mushroom extract soothes.

The renewal note

Tripeptide-1 signals collagen renewal at the site that creases first, the long-game passenger in a formula built for visible freshness.

Ten ingredients

Around the eyes, restraint is a feature: everything present has a job, and nothing is along for the marketing.

Tired-looking, shadowed and dull under-eyes; early fine lines; screen-heavy lives, and vitamin C devotees who want the eye area included in the program at last.

Worth knowing

Real ascorbic acid can tingle briefly on first uses even in this gentle build, keep it to the orbital bone, not the lash line. Fragrance-free and alcohol-free. Dark circles that are structural (hollowness, pigment deposits) are a clinic conversation; this addresses the tired-and-shadowed kind.

Mornings: pat one or two drops around the orbital bone with the ring finger and let it absorb before eye cream, SPF and makeup.

Store cool and tightly capped, vitamin C ages in light and air.

Use alongside

The morning half of the iS eye pairing: C Eye Serum for the day shift, Youth Eye Complex as the peptide night shift, or Youth Eye over it in the morning for the full stack. It slots beneath any eye cream on the shelf, and alongside a facial vitamin C without conflict; the doses are calibrated separately.
