AOU All Day Mascara: four official options vs three at Olive Young, in five checks

Five checks to distinguish AOU Korea's four-option listing from three-option titles at Olive Young Korea and US, plus 01/02 and eye hygiene.

Older YUCHAE video featuring AOU 01 and 02, NOT every current variant · 유채 YUCHAE (Korean beauty creator) · YouTube

Korean brand AOU currently titles its listing All Day Mascara (4 colors). Korean creator YUCHAE's older video features the 01 Volume and 02 Longlash items, but does not prove the complete current option range. An October 2026 Mnet original programme's published makeup list also names 01 Volume Black and 02 Longlash Black. Brand claims about smudge resistance are marketing, not tests performed by this site. A Korean marketplace listing sold by HEMEKO Co., Ltd. names **01 Volume Black, 02 Longlash Black, 03 Volume Brown and 04 Longlash Brown**. This is a dated seller menu, not proof of identical global labels, packaging, or formulas. **Retail listing difference checked 4 November 2026:** AOU's Korean brand website calls this a four-option product. Olive Young Korea titles its product '3 colors', while Olive Young US uses '3types'. These are retailer listing labels, not proof that any specific fourth shade was discontinued, that markets share the same assortment, or that only three units remain. Check the orderable variants and physical packaging at your own seller.

  1. 01

    Read the four-option Korean listing

    AOU Korea lists a four-option All Day Mascara product. Do not assume the older video's two options describe all four present-day items. The Korean HEMEKO seller lists **01 Volume Black / 02 Longlash Black / 03 Volume Brown / 04 Longlash Brown**. Recheck the option name and number on the local product and package. **Check the selling market (4 Nov 2026):** AOU Korea titles its listing as four options; Olive Young Korea says '3 colors' and Olive Young US says '3types'. Verify the actual variant selector at checkout and the label on the tube. Do not guess which of the official four options is missing from a retailer's assortment.

    Separate 01 and 02

    Mnet's October 2026 makeup list names 01 Volume Black and 02 Longlash Black. Verify your actual seller option and tube label rather than assuming identical brushes across types. The Korean seller's 01/02 options are Black Volume/Longlash, while 03/04 are Brown Volume/Longlash. Numbers and sizes in overseas retailers may vary; match both name and code.

    Apply with a clean brush

    Wash hands, apply a small amount along lashes away from the eye's inner surface, and never share mascara. Stop immediately if it stings.

    Avoid clumps and unsafe mixing

    Start with a light coat and add a little more only if wanted. Never rewet dried-out mascara with saliva or water: the US FDA warns this can introduce microbes and dilute preservatives. Keep the wand and tube opening clean, and stop if your eyes become irritated.

    Remove gently and inspect product age

    Check the period-after-opening symbol and directions on the actual AOU package first. The US FDA says manufacturers commonly advise replacing mascara two to four months after purchase, but that is NOT a verified AOU-specific expiry. Discard eye makeup you were using when you developed an eye infection, and avoid eye cosmetics until healed. Seek medical care if symptoms persist. Remove mascara gently with an appropriate eye-area remover at night.

✦ Helpful tips

  • A 2023-era demonstration does not verify all 2026 variations.
  • Waterproof and longwear claims were not independently tested.
  • The AOU four-option, Olive Young Korea '3 colors' and Olive Young US '3types' descriptions were checked on 4 November 2026. They do not establish stock levels, discontinuation or identical regional assortments.

ⓘ Keep in mind

  • The US FDA advises discarding eye cosmetics used when an eye infection develops. Pause eye makeup during infection or inflammation; seek medical advice for persistent symptoms.
  • Never share mascara, add water or saliva to dried mascara, or apply eye makeup in a moving vehicle. Wash hands and keep applicators clean.
  • The FDA's general two-to-four-month manufacturer guidance is not an AOU-specific legal expiry. Follow the actual product's printed expiration and period-after-opening instructions.
