★ THE OIAD SIGNATURE
COVERAGE, MIRROR FINISH, LONG-LASTING WEAR
Makeup formulas that truly last from morning to night.
OIAD focuses on long-lasting makeup performance: buildable coverage, perfecting finish, textures that don’t crease. These are the pillars that define the brand’s signature.
✦ PILLAR 01
MIRROR FINISH
The signature concealer offers a perfecting, almost smoothing finish — the "mirror" effect that blurs imperfections without freezing the face. A texture designed to stay flexible all day.
✦ PILLAR 02
BUILDABLE COVERAGE
One layer to blend, two for full coverage. OIAD formulas build up without heaviness or mask effect, ideal for dark circles and redness.
✦ PILLAR 03
LONG-LASTING WEAR
The "Once in a Day" DNA: one application in the morning that lasts all day, no touch-ups, no transfer, and no cracking in tension areas.
A simple promise: you apply makeup once, and it lasts all day. That's the whole spirit of OIAD.

OIAD FAQ
Everything you need to know about long-lasting K-beauty makeup.
Which OIAD product to start with?
The Cover Perfecting Mirror Concealer, without a doubt. It’s the brand’s historic bestseller: a concealer that covers dark circles and imperfections with a smoothing mirror finish, without cracking throughout the day.
Who is the Cover Perfecting Mirror Concealer for?
For those who want strong but flexible coverage — without cakey effect or lines. Especially suitable for pronounced dark circles, localized redness, and skin that tightens by the end of the day with other concealers.
How to apply the OIAD concealer?
Small amount, applied in dabs. Place the product in dots on the area to cover, then tap with your finger or a damp sponge. Build coverage gradually rather than applying a thick layer — this is the key to a mirror finish without a cakey effect.
How long does OIAD last?
The brand’s DNA is precisely long-lasting wear — hence the name “Once in a Day.” One application in the morning is designed to last all day without touch-ups, even on tension areas (smile lines, under eyes).
Is OIAD suitable for sensitive skin?
The formulas are designed to remain flexible and comfortable, but like any full-coverage makeup, do a patch test on the crease of your elbow if your skin reacts strongly. Check the INCI according to your personal sensitivity.
Are OIAD products on Ma Petite Corée authentic?
Yes, 100%. Ma Petite Corée has been based in Seoul since 2017 and sources directly. Each product is new, sealed, and shipped from Korea, with no customs fees charged to you in the EU.
