Powerful-Strength Dark Circle Reducing Vitamin C Eye Serum

Ten percent pure vitamin C is a bold dose anywhere on the face — around the eyes, it's almost unheard of. Kiehl's Powerful-Strength Dark Circle Reducing Vitamin C Eye Serum brings that strength to the under-eye, pairing it with tri-peptides and hyaluronic acid to brighten circles, smooth lines and depuff.

What it actually does

• Brightens the under-eye. Pure vitamin C at 10% visibly smooths lines and lifts dullness in the eye area.
• Targets both kinds of dark circles. Tri-peptides work on the look of blue (vascular) and brown (pigment) shadows.
• Plumps fine lines. Fragmented hyaluronic acid improves the look of texture and softens crow's feet.
• Fast, measured results, per Kiehl's: in an 8-week US clinical study of 52 panelists, dark circles — blue and brown — were shown to look diminished by 16% within 7 days.
• Gluten-free formula targeting fine lines, dark circles and puffiness.

How to use

1. After cleansing, dispense a small amount onto your fingertips.
2. Gently pat and smooth it under the eye along the orbital bone, out to the crow's-feet area — never on the eyelids themselves.
3. Use morning and evening. A little warmth or tingling can occur and is noted by the brand.
4. Sensitive skin? Start with fewer applications per week and build up as tolerated; scale back if irritation appears.
5. Keep it out of your eyes — rinse immediately if contact happens.

Questions

It tingles — is that normal?

Kiehl's notes that a feeling of warmth or tingling can occur with this concentration of vitamin C. If it goes beyond mild, cut back to fewer applications per week and rebuild gradually. Persistent discomfort means reduce frequency or stop.

How quickly will I see a difference?

The brand's clinical study recorded a 16% visible reduction in dark circles within 7 days, measured over an 8-week US study of 52 panelists. Expect gradual brightening rather than an overnight transformation.

Can I apply it on my eyelids?

No — Kiehl's directs application under the eye and out to the crow's-feet region only, along the bone. Keep it off the lids and out of the eyes; rinse right away if any gets in.
