A useful cushion foundation guide should help you order the right formula, shade and size. A shade number alone is not enough to identify the product in your basket.
This is a shopping guide based on brand and retailer information, reviewed on 20 September 2026. We have not conducted a hands-on wear test or verified a match on your skin. The product photograph is supplied by Mirai Skin.

Start with the exact cushion formula
TIRTIR sells several cushion lines. Red, All Cover, Aura and AI Filter are separate products; a photo of a red compact should not stand in for the entire range. Start by recording the full name of the product you intend to buy.
This guide links specifically to the TIRTIR Mask Fit Red Cushion, 18 g, at Mirai Skin. It does not cover every formula or promise that a shade will look identical across them.
Make a shade shortlist before opening the basket
Use TIRTIR’s official shade finder as one starting point. It offers a Red Cushion shade tool. Treat an online result as a shortlist, rather than a guaranteed match.
Write down the full brand, formula and shade of a foundation that already suits you. Then note what you want to change: depth, undertone, finish or coverage. These are different shopping questions. Wanting less shine does not automatically mean you need a lighter shade.
If you can try the exact formula before buying, compare it in ordinary daylight as well as indoor light. If you cannot, look for clearly identified swatches of the same formula and shade. A filtered photograph or an unnamed compact is a weak basis for a purchase.
Depth, undertone and finish are separate decisions
Depth describes how light or deep the shade appears. Undertone describes its color direction. Start with both, then compare the finish and coverage you want. A number or letter from another brand is not a universal shade match.
If a swatch changes appearance after application, compare it after it has settled and in more than one light. We have not measured oxidation for this formula, so we do not recommend that everyone automatically buy one shade lighter. A shade finder, swatches and a familiar foundation reference should narrow your options; none guarantees a match.
The cushion’s SPF label also does not make a light makeup application equivalent to applying sunscreen as directed.

Mirai’s listing was available when checked, but individual shades had different stock states. Availability of the product overall does not mean every shade is in stock. The retailer title and the brand’s broader range can also differ, so this guide does not treat a headline shade count as the range you can buy today.
Stock check — 8 October 2026: Mirai listed 45 shades, of which 42 were available. 13C Fair, 15C Fair Porcelain and 17N Vanilla were unavailable at this check. This is a dated snapshot, not a reservation or a shade recommendation. If one of those is your match, check for a restock rather than ordering a different undertone just because it is available. Confirm your exact selection on the product page before paying.
When to wait before buying
Pause if you have two plausible shades and no useful reference, or if the only available option is one you already suspect is wrong. Check the retailer’s current returns conditions before opening or testing a delivered cosmetic. Do not assume that an opened shade mismatch can be returned.
For example, a shopper who knows their current foundation is too warm should first resolve the undertone question. Buying the next darker number simply because it is available does not answer that question.
Use a five-field order note
Before leaving this guide, write: Mask Fit Red Cushion / 18 g / full shade number and name / compact or refill / delivery country. Copy the shade from the retailer selector rather than relying on the compact photo. At checkout, compare every field with the item in the basket.
A useful stop rule: if your chosen shade is unavailable, return to your shortlist rather than substituting the closest number. The 18 g listing showed purchasable variants on 4 October 2026; that does not establish stock of your chosen shade. We do not select a variant or send you directly to a shade-specific checkout.
Ready to choose?
Keep your shortlist beside the Mirai Red Cushion product page, select the full shade name, and confirm it again in the basket. That final check matters more than choosing a shade quickly.
