Eyelash extension glue is a professional cyanoacrylate-based adhesive used to attach individual lash extensions to natural lashes. Unlike strip lash glue, professional lash adhesive creates a semi-permanent bond designed to remain attached until the natural lash sheds.

Actual retention varies depending on the adhesive formula, lash preparation, attachment technique, room conditions, client aftercare, and the natural lash growth cycle.

Professional eyelash extension glue should only be used by trained lash technicians. These adhesives cure quickly and release vapours during polymerization, so they are not suitable for self-application, DIY cluster lashes, or use with open eyes.

Always follow the product instructions, keep the client’s eyes fully closed, and work in a properly ventilated lash room.

Traditional eyelash adhesive uses moisture in the air to cure. Higher humidity generally speeds up curing, while lower humidity slows it down.

If the humidity is too high, the adhesive may cure before the extension reaches the natural lash. This can create a weak or brittle bond and cause lashes to pop off. If the room is too dry, extensions may slide, stickies may increase, and the adhesive may take longer to stabilize.

Use a digital hygrometer to monitor your lash room throughout the day. A humidifier, dehumidifier, or air conditioner can help keep your working environment stable.

Common signs include:

• Extensions popping off during application
  
• Volume fans closing before placement
  
• Adhesive appearing dry before attachment
  
• Poor retention despite correct lash preparation
  
• Glue drops becoming thick too quickly
  

Try reducing the room humidity, refreshing the glue drop more frequently, or switching to a slightly slower adhesive.

Common signs include:

• Extensions sliding after placement
  
• Increased stickies
  
• Fans moving or closing on the natural lash
  
• Unstable attachment
  
• Longer application time
  

Try increasing the humidity or selecting a faster-drying LymeeBeauty adhesive.

Black lash glue is the standard choice for most classic, volume, and hybrid sets because it blends naturally with black extensions and creates a deeper lash line.

Pink adhesive adds a creative detail and can make the adhesive bead easier to see during application.

Clear UV/LED glue is suitable for brown, coloured, or creative lash sets where a black attachment point may be visible. LymeeBeauty UV/LED Lash Glue is currently available in clear, black, and purple options.

Clients may react to different adhesive ingredients, including cyanoacrylate or pigments. Clear adhesive should not be described as allergy-free or completely safe for sensitive clients.

UV/LED lash glue is a light-cured adhesive used with a compatible professional lash lamp. The lash artist places the extension first and then activates the adhesive with the lamp for approximately 0.5–1 second.

Because curing is controlled by light, the adhesive is less dependent on room humidity than traditional lash glue. It can be useful for changing seasons, unstable salon conditions, detailed lash mapping, and artists who want greater control over the curing moment.

UV/LED adhesive must be used as part of a complete professional system, including:

• A compatible UV/LED lash lamp
  
• Client eye protection
  
• UV-protective glasses for the technician
  
• Correct lamp positioning and curing distance
  
• Professional UV lash training

Store eyelash extension glue upright in a cool, dry, and dark place away from direct sunlight, heaters, windows, and warm equipment.

For best results:

• Keep the bottle inside an airtight adhesive container.
  
• Add silica gel to help control moisture.
  
• Shake the bottle thoroughly before use.
  
• Wipe the nozzle with a lint-free wipe after dispensing.
  
• Close the cap immediately and securely.
  
• Label the bottle with the date it was opened.
  
• Do not store opened glue in the refrigerator, as condensation may enter the bottle.
  

LymeeBeauty recommends using traditional opened adhesive within approximately 4–6 weeks for optimum performance. Unopened traditional adhesive generally has a shelf life of up to six months from its production date when stored correctly. UV/LED Lash Glue has separate storage guidance: approximately 3–4 months unopened and up to two months after opening. LymeeBeauty storage guidance

Replace the adhesive if:

• The texture becomes thick, stringy, or unusually gloopy.
  
• The colour or consistency changes.
  
• The ingredients no longer mix evenly after shaking.
  
• The glue drop develops a skin unusually quickly.
  
• Drying time or retention becomes inconsistent.
  
• The bottle has remained open beyond its recommended working period.
  

Do not add water or other liquids to thin expired lash glue.

LymeeBeauty Super Bonder is a professional finishing liquid used to help stabilize and protect the adhesive bond after application. When used correctly, it can support improved flexibility and retention while helping reduce lingering adhesive vapours.

Apply only a small amount to the adhesive bonding area according to the product directions. Super Bonder does not replace correct lash preparation, proper attachment, fresh glue, or controlled salon conditions.

Lash Primer helps remove residual oil, makeup, and surface impurities from the natural lashes before application. It can improve adhesive contact, particularly for clients with oily lashes.

Avoid overusing primer on naturally dry or porous lashes. Always cleanse the lashes first and allow them to dry completely before applying adhesive.

For traditional lash adhesive, refresh the glue drop approximately every 15–20 minutes, or sooner if the drop becomes thick, develops a skin, or stops behaving consistently.

High temperature, airflow, and humidity may cause the glue drop to age more quickly.

Beginners should generally choose a slower adhesive that provides enough time for correct placement. LymeeBeauty Supreme Glue, with a working time of approximately 1–2 seconds, is more forgiving than an ultra-fast 0.3-second adhesive.

Infinity and Berry Lock are better suited to experienced artists who can isolate and attach immediately.

Infinity and Berry Lock both cure in approximately 0.3 seconds and are designed for advanced technicians with a fast, confident application speed.

Berry Lock works within a slightly wider listed temperature and humidity range and features a strawberry aroma, while Infinity is a fast, glossy-black adhesive designed for efficient salon application.

UV lash glue contains light-reactive ingredients that cure when exposed to a compatible UV/LED lash lamp. The technician positions the extension first and then activates the lamp to set the bond.

UV lash glue is less dependent on humidity than traditional eyelash adhesive because curing is activated by light. However, room conditions, lash preparation, glue freshness, lamp position, and application technique can still affect the final result.

LymeeBeauty UV/LED Lash Glue is designed for fast curing under a compatible lamp. The exact time depends on lamp power, wavelength, distance, and positioning, so always follow the instructions for the specific glue and lamp combination.

No. UV lash glue requires a compatible curing lamp. Without the correct light source, the adhesive may remain uncured and cannot create a reliable bond.

No. Traditional lash adhesive is designed to cure through contact with moisture in the air. Only use a UV/LED lamp with adhesive specifically formulated for light curing.

A professional UV lash system should only be used by trained technicians following the manufacturer’s instructions. The lash artist should wear UV protection glasses, and the client’s surrounding eye area should be correctly protected with suitable eye pads and eyelid covers.

Avoid directing the light into open eyes or exposing the skin longer than instructed.

UV curing may reduce the amount of time that uncured adhesive and vapours remain active, but it does not make the adhesive allergy-free. Clients can still react to adhesive ingredients.

Do not use UV lash glue on clients with a known adhesive allergy unless advised otherwise by an appropriate medical professional. Stop the service if irritation, swelling, pain, or an unusual reaction occurs.

UV systems can provide more placement control, but artists should already understand isolation, adhesive control, correct attachment, eye protection, and lamp positioning. Professional UV lash training is recommended before using the system on clients.

• Black: Best for standard black classic, hybrid, and volume sets.
  
• Clear: Ideal for brown, coloured, or creative lash extensions.
  
• Purple: Provides a distinctive application colour and creative alternative.
  

Adhesive colour does not replace correct product selection, curing technique, or client consultation.

Yes. It can be used for classic, volume, promade, hybrid, wet-look, and wispy sets. Use a controlled amount of adhesive to prevent bulky attachment points or closed fans.

Retention varies according to lash preparation, attachment quality, natural lash growth, curing technique, aftercare, and client habits. No adhesive can prevent extensions from shedding with the natural lashes.

Yes. UV glue is less humidity-dependent, but a clean, comfortable, and stable lash room still supports consistent application. Temperature, airflow, lash cleanliness, glue freshness, and lamp positioning can all influence performance.
