MIBA Ionized Calcium Double Cushion RX Refill No.21 — 25g dewy, long-lasting hydration

This refill replaces the cushion sponge in MIBA's oversized Double Cushion RX compact, offering concentrated coverage and luminous skin texture without buying a whole compact. Season 2 upgrades include a patented ion calcium mineral-water complex, Australian Blue Mountain Cave Water, pink plankton extract, and triple hyaluronic acid for resilient moisture. The product is a 25 g / 0.88 oz refill in shade No.21, designed to slip into the large-capacity cushion for everyday and full-coverage looks.

How does this refill improve coverage compared with standard cushions?

The Double Cushion RX formula is engineered for stronger concealment while maintaining a natural, dewy surface. Special emulsifiers and a buildable pigment system allow you to layer without patchiness, covering freckles, redness, and discoloration more effectively than light-tint cushions.

• High-pigment core for spot coverage and color correction
• Buildable formula that avoids cakey texture
• Large 25 g refill supplies more product per replacement

What skin feel and finish can I expect during wear?

Season 2 balances luminous radiance with lasting hydration: the finish reads moist and glowing rather than oily. Triple hyaluronic acid and mineral-water ingredients create a skin-like sheen and help the foundation settle smoothly, keeping makeup comfortable throughout the day.

• Moist, dewy finish suitable for normal to dry skin
• Hydrating actives help reduce tightness and flaking
• Formulation designed to sit evenly on skin without settling into fine lines

Which unique ingredients are included and why do they matter?

Key actives set this refill apart: a patented ionized calcium mineral-water complex, Australian Blue Mountain Cave Water, pink plankton extract, and triple hyaluronic acid. These ingredients are chosen to support moisture retention, impart a natural glow, and help the formula maintain integrity under varied conditions.

• Ion calcium mineral water — patented complex for balanced mineral content
• Australian Blue Mountain Cave Water — provides naturally sourced minerals
• Pink plankton extract — adds radiance and botanical-derived nutrients
• Triple hyaluronic acid — multi-weight hydration for surface and deeper moisture

How practical is this refill for daily use and travel?

This refill is built for convenience: its oversized 25 g capacity reduces refill frequency and fits the Big Cushion's large sponge and mirror system. The cartridge design makes swaps clean and straightforward, so you can refresh your compact without wasting product.

• Large refill reduces cost-per-use versus smaller cushions
• Easy to install into the Big Cushion SEASON 2 compact
• Works with the cushion’s big puff and mirror for quick touch-ups

Who is this for: The MIBA Ionized Calcium Foundation Double Cushion RX Refill No.21 is aimed at people who want fuller coverage with a luminous, hydrated finish—especially those who prefer fewer refills and a compact system with generous capacity. It’s suited for anyone seeking buildable concealment for spots, redness or uneven tone while keeping skin comfortable; ideal for regular users of cushion compacts who own or plan to buy the Big Cushion SEASON 2 case.
