The diffrence btw Toxic adeshive and the healthly one.

The Science of Eyelash Extension Adhesive

What are the components of lash extension adhesive?
Typical components:

• 90–95% Cyanoacrylate

• 5–10% Additives like stabilizers, thickeners, curing accelerators, pigments, etc.

Types of Cyanoacrylate:

Methyl-Cyanoacrylate:
Toxic. Only for industrial use. Can dissolve proteins and cause permanent blindness. ❌ NEVER use glue with this ingredient!

Ethyl-Cyanoacrylate:
Most common in lash adhesives. Fast-drying and strong hold, but strong odor and may irritate eyes.

Alkoxy-Cyanoacrylate:
8x more expensive than Ethyl. Low-odor and hypoallergenic.

Butyl-Cyanoacrylate:
Used in medical/veterinary fields. Slower drying and weaker bond but gentler.

Methoxy-Cyanoacrylate:
Least irritating and odorless. Designed to avoid reactions caused by Ethyl or Butyl. Slower drying.

Are there adhesives without Cyanoacrylate?

❌ No. All lash glues contain Cyanoacrylate – it’s the only effective component that cures with humidity.

Humidity, Climate & Glue

?️ Ideal climate:

• Humidity: 45%–60%

• Temperature: 22–26°C

? High humidity = faster drying
? Low humidity = slower drying

?️ Warm = thinner glue, fast dry
? Cold = thicker glue, slow dry

Are there glues unaffected by climate?
❌ No. All Cyanoacrylate glues are sensitive to humidity.

Which glue to choose in hot & humid climates?

Use: A/C, fans, dehumidifier.
Recommended glues:

• IBeauty Pro-Cling (2–3 sec dry)

• Summer Glue Oil Water Resistant (1–3 sec)

• IBeauty Ultra Bonding Glue (2–3 sec)

• Master Oil Water Resistant (1 sec – for advanced users)

• IBeauty Orange Cap - Ultimate Bond (3 sec – for beginners)

Which glue to choose in cold & dry climates?

Use: Humidifier + heater
Recommended fast-drying glues:

• Master Oil Water Resistant (1 sec)

• R88 Pink (1 sec – advanced) / R88 Green (1–2 sec – medium)

• IBeauty Ultra Super (1–2 sec – medium/advanced)

• IBeauty Super Plus (1 sec – medium)

• IBeauty Hyper Bond (0.5 sec – advanced)

• Magnetic Pink Lash (0.5–1 sec – lasts 2–3 months after opening)

How to improve retention?

1️⃣ Correct application with the right glue amount
2️⃣ Proper cleansing – Primer before, Bonder after

What ruins retention?

• ❌ Expired or poorly stored glue

• ❌ Improper technique – too much/little glue

• ❌ Poor client aftercare

• ❌ Extreme temperature/humidity, no ventilation

What's the "best" glue?

❗There’s no universal best. It depends on:

• Room climate

• Artist’s speed

• Client type

⛔ Common mistake:
Fast-dry glue + slow technician = bad retention
Slow glue + fast technician = slow procedure

Volume Glue Guide:

• Handmade volume = thicker, faster glue (1 sec or faster)

• Pre-made volume = thinner, 1–2 sec drying glue

How to store glue:

✅ Dry, cool, dark place
❌ Don’t refrigerate unless manufacturer says so
✅ Use zip bags with desiccant
✅ Write opening date

Allergies & Irritations

Why allergies happen:
Curing fumes may irritate if the eyes aren’t fully closed.

?️ Solutions:

• Hypoallergenic glue (like BIOTHIN)

• Anti-allergy gel to neutralize fumes

• Technician: goggles & mask with filter

Is lash glue dangerous?

❌ No. Cyanoacrylate is non-toxic, used in medicine, and clears from the body in 2 months.

Eye issues:

• Stye (hordeolum)? Caused by bacteria, not glue. Sterilize everything!

• Itchy eyes? Could be:

  • Glue touching mucosa

  • Too much glue

  • Poor isolation

  • Rubbing eyes

Fast & Hypoallergenic Glues?

Hard combo! Fast = stronger chemicals. Gentle = slower.
