Lashify Underlash Bond — Whisper Light Classic Dual-Sided Black & Clear, Micro-Flex, Biotin-Infused

Lashify Whisper Light® Classic Dual-Sided Underlash™ Bond is a two-in-one underlash adhesive pairing a black micro-mascara side and a clear precision side for customizable, flexible hold under natural lashes.

Designed to give you precise control when applying underlash extensions or finishing your lash look, this dual-sided bond combines buildable adhesion with featherweight movement. The formula uses Micro-Flex Technology so the bond flexes with your natural lashes, and its biotin infusion supports a gentle routine. Free from cyanoacrylates and formaldehyde, the product is vegan and cruelty-free with a 6-month period-after-opening.

How do I use the two sides to get a seamless underlash finish?

Start with the black micro-mascara side to lightly coat natural lash bases for even tint and initial hold. Use the clear precision tip to place thin, targeted lines at the lash base or to reinforce specific points. Layering is possible: one thin coat for daytime looks, up to three thin layers for extended wear.

• Apply black side through natural lashes for even distribution and blending.
• Use clear side to set adhesive exactly where you need it at the base.
• Allow thin layers to dry between applications for stronger hold.

Will this bond feel heavy or restrict natural lash movement?

No—the Whisper Light formula is engineered to remain lightweight and flexible so it moves with your lashes. Micro-Flex Technology creates a cushioning layer that bends rather than hardens, reducing stiffness and helping maintain comfort during wear. It’s intended to minimize pulling or rigidness commonly associated with stronger adhesives.

• Lightweight texture designed for natural movement.
• Buildable without becoming stiff when applied in thin layers.
• Formulation avoids harsh resins linked to rigid finishes.

Is this safe for sensitive eyes and compatible with Lashify tools?

The bond is formulated without cyanoacrylates and formaldehyde and includes biotin for a gentler application experience. It’s created to pair with Gossamer lashes, the Fuse Control Wand, and Lashify-compatible sealers so you can integrate it into your Lashify routine. As with any eye product, patch testing is recommended before full use.

• Biotin-infused and free from cyanoacrylate and formaldehyde chemicals.
• Works with Gossamer lashes and the Fuse Control Wand for seamless application.
• Recommended patch test for those with extreme sensitivity.

How should I store and layer the bond for best performance?

Keep the bottle capped tightly and stored in a cool, dry place away from direct sunlight and extreme temperatures to preserve formula integrity. Apply thin coats and let each layer dry fully before adding another—this maintains flexibility and prevents buildup. Avoid leaving the product in hot cars or freezing conditions which can alter performance.

• Store away from heat, cold, and direct sun to protect the bond.
• One layer for everyday wear; up to three thin layers for multi-day hold.
• Close cap tightly after each use to prevent drying or contamination.

Who is this for: Lashify Whisper Light Classic Dual-Sided Underlash Bond is designed for anyone who wants precise underlash styling with a flexible, lightweight finish—ideal for at-home lash enthusiasts, professional stylists, and users of Lashify systems who prefer customizable layering and discreet black blending or targeted clear placement.
