Professional Lash Extension Adhesive — 0.3s to 2s | Black & Transparent

The right lash extension adhesive is the single biggest factor in 4-week vs. 8-week retention.
Swaniya's professional lash glue range covers every skill level and salon environment — from ultra-fast 0.3s for expert lash artists working in high humidity, to a forgiving 2s formula for lash students and training academies. All formulas use a thin-viscosity cyanoacrylate base, are waterproof, oil-proof, and FDA & CE certified for professional use.

How to Choose the Right Lash Glue

How To Use Lash Extension Glue

1. Prep — Cleanse natural lashes with Eyelash Primer before every set — increases adhesion and retention by 30–50%
2. Shake — Shake the bottle vigorously for 30 seconds before dispensing
3. Dispense — Place a small drop onto a jade stone or glue ring; replace every 15–30 minutes
4. Dip — Dip the lash extension base 1–2mm into the adhesive drop — use minimal glue for a clean bond
5. Apply — Place 0.5mm from the lash line using proper isolation; hold until bonded (time varies by variant)
6. Cure — Use a Lash Bonder after the set to instantly cure and lock in retention
7. Store — Squeeze out excess air, wipe the nozzle clean, seal tightly, and store upright in a cool dry place

Lash Glue Performance — Temperature & Humidity Guide

• Optimal working conditions: 20–25°C (68–77°F); humidity varies by glue variant (see table above)
• High humidity salon: Choose a faster dry time (0.3s or 0.5s) to prevent stickies and poor isolation
• Low humidity or cold environment: Glue cures slower — choose a slower dry time or use a nano mister to boost ambient humidity
• Winter application: Naturally slower cure time than summer — this is expected and does not affect bond quality or retention
• Retention is technique-dependent: Isolation quality, placement accuracy, and primer use all significantly affect how long lash extensions last — not just the glue
• White residue on bottle exterior: Caused by moisture reacting with cyanoacrylate on the bottle surface during shipping — does not affect the glue inside; store in a dry, ventilated space

FAQ

Which lash extension glue has the longest retention?

0.3s Glue offers the longest retention (~8 weeks), followed by 0.5s Glue (6–8 weeks). Faster-curing cyanoacrylate adhesives generally form a more complete bond, resulting in better retention. Retention also depends significantly on the artist's isolation technique and client aftercare routine.

Can I use the same lash glue for classic and volume sets?

Yes — all Swaniya lash adhesives work for classic, volume, mega-volume, and hybrid sets. The dry time affects your working speed, not the lash style. Thin viscosity across all variants makes them suitable for both classic 1:1 placement and volume fan application.

How do I improve lash extension retention?

Use Eyelash Primer before every set, maintain optimal humidity during application (see table above), apply Lash Bonder after the set, and advise clients to cleanse with Lash Shampoo every 2–3 days and avoid oil-based products near the eye area.

My client is sensitive to lash glue — what should I use?

Use our Low-Fume Sensitive Glue, which features a reduced-fume cyanoacrylate formula designed for sensitive or allergy-prone clients. You can also use a nano mister to cure the adhesive faster and reduce fume exposure time.

What is the difference between black and transparent lash glue?

Black glue creates a defined, liner-like effect at the lash base — ideal for classic and dark lash sets. Transparent glue dries completely clear — ideal for colored extensions, ombre lashes, and wispy sets where black glue would muddy the color or show through.

How should I store lash extension adhesive?

Store upright in a cool, dry, ventilated space away from direct sunlight. After each use, squeeze out excess air, wipe the nozzle clean with a dry microbrush, and seal tightly. Opened glue is best used within 4–6 weeks for optimal performance. Do not refrigerate.
