Which shade is right for you?
The five shades on five skin tones
  • PinkFair to light skin. Cool or neutral.
  • PeachLight to medium skin.
  • Beige PeachMedium to tan skin. Warm or golden.
  • Maroon BrownTan to deep skin.
  • MintFor redness. All skin tones.
What makes it different?

It's a brightener, not a concealer. Concealer is thick and beige, so over a blue-purple shadow it goes grey and sinks into your lines. This is sheer and pink. It cancels the shadow and bounces light into the hollow, so it looks like rested skin, not makeup.

Does it work on my skin?

It's made for skin over 40, in five shades from fair to deep. Mint is for redness. Not sure which one is yours? Tap "Which shade is right for me?" above. If you pick wrong, we'll swap it.

How do I use it?

Pick up a dot on your ring finger. Tap it into the inner corner and along the shadow under your eye. That's it. Wear it on its own, or under concealer and use half as much.

How does the money-back guarantee work?

Use it for up to 30 days. If you're not happy with how your under-eyes look, email us within 30 days and we'll refund your purchase.

“I’ve worn concealer every single day since I turned 42, and by lunchtime it had always gone grey. My husband asked me last week if I’d started sleeping better. I hadn’t. I nearly cried.”

“I’ve spent hundreds on concealers that creased and eye creams that did nothing. This is the first thing that actually hides the shadows without looking like makeup. One tap and I look like I slept.”

“I’m not exaggerating when I say this replaced my concealer. It’s sheer, it doesn’t settle into my lines, and the peach cancels the grey under my eyes instead of just painting over it.”

“Honestly shocked. I have deep hollows under my eyes and concealer always made them look worse, cakey and grey. This just softens the shadow so it reads as skin. I wear it alone most days now.”

“I’m a night shift nurse and my under-eyes have always been dark. One tap of the Peach and the grey is gone. My coworkers asked what I changed because I don’t look exhausted anymore.”

Take 10 years off your under-eyes in one tap

Split face: left under-eye with a blue-purple shadow, right under-eye brightened after one tapBeforeAfter

After 40, the skin under your eyes is the thinnest on your face, so it's the first place that shows age. A dark shadow there makes you look tired and older than you feel. You can sleep eight hours and still get asked if you're okay. You look fine in the mirror, and then tired in every photo.

A brighter under-eye is a younger under-eye. One tap of pink, and yours look rested again.

Works in seconds
Looks like skin, not makeup

How one tap brightens your under-eyes

Pink Blue-purple

Pink cancels the blue-purple. Pink sits opposite blue and purple on the color wheel. A thin layer turns the shadow back to skin color. Beige concealer just paints over it, and that's why it goes grey.

Light softens the hollow. After 40, a lot of the darkness under your eye is a shadow from a hollow, not pigment. Light-diffusing pigments scatter light into it, so the shadow stops looking dark.

All it takes is a dot of balm and one finger. About ten seconds.

Cancels blue-purple
Softens the hollow

Every tap helps fine lines look softer over the weeks

Every tap also brings Acetyl Hexapeptide-8, a peptide used in skincare for the look of expression lines.

Questions

How long until I see results?

Right away. The shadow is cancelled the moment it's blended. Tap it on every morning, and over the weeks the peptide helps the fine lines around your eyes look softer.

Does it work on deep hollows?

Yes. It softens the look of the shadow a hollow casts, so it reads as rested skin, not shadow.

Is it safe for sensitive skin?

It's fragrance-free. Nothing heavy or perfumey near your eyes.

How long does one compact last?

A dot per eye. One compact lasts most people two to three months of daily use.

Can I wear it with my other makeup?

Put it on after your moisturizer. Foundation or concealer, if you use them, go on after the balm.

Can I use it with the Koseon Eye Mask?

Yes. They're made to go together. The mask stays on about 45 minutes, on clean skin. Tap the brightener on in the morning.
