Cosmo Filler Serum + Fillerina Mask Offer Package

Cosmo Filler Serum + Fillerina Mask Offer Package combines the Cosmo Absolute Filler Serum with the Fillerina 12HA Densifying Plumping Mask — two fast-acting formulas that together deliver concentrated hydration, visible facial plumping, and improved skin firmness in a single session.

It pairs seamlessly with the Fillerina daily cream routine, working as a weekly booster that accelerates results between 14-day treatment cycles.

Key Ingredients

• Sodium Hyaluronate (Cosmo Serum), deeply hydrating HA that plumps fine lines, restores lost moisture in the dermis, and primes the skin surface to receive the mask's concentrated formula more effectively.
• Beta-Glucan (Cosmo Serum), reinforces the skin barrier and reduces surface inflammation — particularly useful for sensitized skin or skin recovering from environmental stress.
• Hydroxypropyl Chitosan (Cosmo Serum), forms a protective film on the skin that promotes tissue regeneration and holds the serum's actives in contact with the skin during absorption.
• 12 Hyaluronic Acid Molecules (Fillerina Mask), twelve HA variants at different molecular weights deliver a concentrated filler dose across every skin depth simultaneously during the 20-minute mask application.

Benefits

• Visible Results in One Session, the combination produces measurable plumping and improved skin firmness within 20–30 minutes — suitable as a standalone pre-event treatment when time is limited.
• Serum + Mask Synergy, the Cosmo serum applied first creates a primed, hydrated base that amplifies the impact of the Fillerina mask — the two formulas together outperform either one used alone.
• No-Rinse Application, both products are leave-on. The mask absorbs fully, leaving no sticky or greasy residue after the 20-minute treatment.
• Weekly Booster for Fillerina Users, for those already on a Fillerina daily routine, this bundle delivers a concentrated double-dose session that visibly accelerates results between treatment cycles.

Frequently Asked Questions

Q: How often should I use this bundle?
A: Once a week as an intensive booster, or as needed before events. The Cosmo serum can be used daily on its own — morning or evening after cleansing.

Q: Do I need to rinse the mask off?
A: No. The Fillerina mask is designed to be fully absorbed. After 20 minutes, gently pat any remaining product into the skin with fingertips.

Q: Can I apply makeup immediately after?
A: Yes, after the mask has fully absorbed. The plumping effect creates a naturally smooth, luminous base that often reduces the need for heavy coverage.

Q: Is this bundle suitable for sensitive skin?
A: Yes. The beta-glucan and aloe in the Cosmo serum make it suitable for sensitized skin. If your skin is very reactive, patch-test both products separately first.

If you want a targeted wrinkle treatment rather than a full-face mask session, the Fillerina Filler Gel + Nee bundle applies the HA complex directly onto specific wrinkle zones with a precision applicator.
