MIBA Ionized Calcium Foundation Double Cushion RX Refill No.21 — 25 g Large Cushion, High Coverage & Hydrating Glow

MIBA Ionized Calcium Foundation Double Cushion RX Refill No.21 is a large-capacity cushion refill that delivers high-coverage, luminous finish with ionized calcium mineral water and triple hyaluronic acids.

This refill is the Season 2 version of MIBA’s Big Cushion line, stocked with a 25 g sponge that pairs with MIBA cushion cases to extend the life of your compact. It blends patented ionized calcium mineral water, Australian Blue Mountain Cave Water, pink plankton extract and a resilient triple hyaluronic acid complex to balance coverage, moisture and a radiant look. The formula emphasizes strong spot-concealing coverage while offering longer-lasting hydration and a luxe presentation with an oversized puff and mirror when used in the original Big Cushion case.

How does this refill deliver both heavy coverage and a natural glow?

The Double Cushion RX formula is engineered to layer coverage without looking cakey, combining pigments that conceal discoloration with light-scattering particles for brightness. Hydrating actives maintain skin flexibility so coverage sits smoothly across expression lines.

• Powerful pigment blend for spots, freckles and redness
• Light-reflecting elements for luminous finish
• Triple hyaluronic acids to keep skin supple beneath coverage
• Designed for buildable application—from medium to fuller coverage

What are the key ingredients and what do they contribute?

MIBA lists several signature components: ionized calcium mineral water, Australian Blue Mountain Cave Water, pink plankton extract from a pink lake, and a triple hyaluronic acid complex. Each ingredient is chosen to support hydration, a fresh appearance, and ingredient stability under varying environmental conditions.

• Ionized calcium mineral water: part of the patented blend to support formula performance
• Blue Mountain Cave Water: a natural-source water used for its mineral profile
• Pink plankton extract: adds antioxidant-rich botanical elements and visual appeal
• Triple hyaluronic acids: delivers layered moisture retention for lasting comfort

How does the Big Cushion format affect use and value?

This is a larger-than-standard refill (25 g) meant to fit MIBA’s Big Cushion compact, offering more product per purchase and a bigger puff and mirror for application control. The format reduces refill frequency and improves cost performance for daily users.

• 25 g large refill for extended use compared with typical cushions
• Big puff and mirror when combined with the Big Cushion case for quicker, even application
• Refill design makes replacement easy and tidy—no full compact disposal
• Optimized for both life makeup touch-ups and stronger coverage needs

Does the cushion handle redness, pores, and dark circles effectively?

The Double Cushion RX emphasizes strong coverage to mask common skin concerns like redness, visible pores and under-eye discoloration. Coverage results will vary by individual, but the product is formulated to target these areas while preserving skin hydration.

• High-coverage pigments target spots, redness and blemishes
• Texturizing components help smooth the look of pores
• Moisture system reduces cakiness around delicate under-eye zones
• Buildable layers allow targeted correction without excess product

Who is this for: MIBA’s Big Cushion SEASON 2 refill suits users who want a refillable, high-coverage cushion with an emphasis on moisture and radiance—ideal for daily wearers seeking extended product capacity, those who prefer buildable coverage for problem areas, and anyone looking to replace or stock up on the No.21 shade for light to light-medium skin tones. It’s also a strong fit for buyers who value patented mineral-water ingredients and a premium refill format with a larger puff and mirror for easy application.
