What are CharmLash eyelash extensions made of?

The main materials we use are high quality PBT (poly-butylene-terephthalate) synthetic fiber. As PBT is very soft, light and can hold the original form, it has been the most widely used material for a long time. Currently, we are supplying two kinds of raw materials: PREMIUM SILK and MINK. Premium Silk is softer, thinner, matte or semi-matte. Mink is thicker, fuller and more popular than SILK. However, both have a very smooth texture.

Are CharmLash eyelash extensions safe for eyes?

With proper care and application by trained professionals, our products are completely safe to use. 

How are CharmLash eyelash extensions categorized?

CharmLash eyelash extensions are categorized by their curls: J, B, C, CC/C+, D, DD/D+, L, L+,LD, M and V. The most commonly used curls are C, CC, D, L, M, as it gives a natural lift to lashes, and is suitable for most natural lash types.J curl: J curl lash is pretty much straight at the base and then it slightly curls a little bit at the end. Therefore, it is not as curly as the other. J curls are the best suited for the clients with straight and downward-facing lashes as well as bottom lash.B curl: B curl lashes are quite similar to the J curl but a little curlier. These lashes have a natural curl that appears straight at the base and then curls at the top. B Curl lashes are perfect for customers whose natural lashes are straight. They're not for those with downward-facing lashes or protruding eyes.C curl: C curl is most commonly used curls for its versatility among different lash types. It has a short and straight base with a natural curl at the end of the extension. If you are looking for a bright, wide-open effect without looking too heavy and dramatic, the C curl will be the best choice for youC+ curl: Basically, C curl and C+ curl look alike, but C+ curl is a bit curlier. This curl allows you to achieve a fresh and natural lookD curl: If you want to get a dramatic eyelash extension set, D curls will be your best friend. They are half-circle shaped, which make them the curliest and dramatically open the eyes. D curls are typically used for special occasions and not long-term wear.D+ curl: D+ is a curlier version of D curl. It is created for customers who want a fluffy set of extra curly lash extensions.L curl: L curl lash is literally shaped like an L. They have a flat base, which allows a stronger and longer bond with the natural lashes, then slightly straight upright. L curls are best suited for customers who have straight and downward-facing lashes as well as bottom lashes. They’re suitable curls for cat-eye effect, perfectly creating a flick effect to the outer eye.LD curl: Basically LD curls are D curl lashes with a straight base. While the straight base allows more attachment surface between lash extensions and natural lashes, the dramatic curl will create an open eye effect by a multiple. LD curl is a great choice for customers with hooded eyes, deep-set eyes or mono lids making a bigger and dramatic look.L+ curl: L+ curl lash has the same flat base as LD curls allowing it to bond really nicely to the straight natural lash, but less curl toward the tip. Designed for an open eye look, with natural down eyelashes, L+ curls are the savor for those with hooded eyes as it draws the lash outward and upward, creating a lot of lift.V curl: V curl has a straight base, but lifts up with more bend. This eyelash is perfect for mono lids, hooded eyelids, downward-facing lashes or any clients who want to crimp their lashes with eyelash curler. V curls will create dramatic vertical uplift that really open the eyes. It is mostly used for creating cat eye lash style.M curl: M curl has a straight base for easier attachment and lifts up with more bend than L curl. It is designed to lift the appearance of downward-angled natural lashes. This curl is idea for cat/fox eye styling as the shorter base allows to place even longer lashes in the outer corner without the fear of making the eye droopy.

Eyelash extensions last up to 2-3 weeks before falling out with the natural lash cycle. They provide a beautiful natural look of flawless, thick, and long lashes, without the need for mascara. However, it depends on the quality of the adhesive glue that you are going to use and in the environment you’re living in.

What is the origin of your liquid?

Our adhesives and liquids are made in South Korea. Our company has spent 2 years researching with Korean partners to create our own products.

Which adhesive is the fastest one?

Our fastest adhesive is Ultra Adhesive and its drying time is 0.5-1 second if you use the recommended temperature and humidity range.Ultra Adhesive works best in 18-22°C (64.4 - 71.6°F) and 45-60% humidity.Please note that the higher the humidity in your room is, the faster your glue will dry! That's why you should remember to change the humidity and temperature in your working room into the right conditions. Ultra Adhesive is drying quickly and should be used only by ADVANCED lash artists who have been experienced in lashing for years.

Which are other kinds of fast-drying adhesives ? 

Asiding from Ultra Adhesive, we also highly recommend other kinds of fast-drying adhesives such as Premium Adhesive, Ultra volume Adhesive and Volume Adhesive. They are all drying in 1-2s and should only be used by HIGHLY EXPERIENCED lash technicians. 

Which kinds of adhesive are suitable for beginners and intermediate lash artists?

For training and practicing, Ultra Blooming Adhesive (2-3s),Supreme Adhesive (2-3s), Blooming Adhesive (3-4s), and Lady Bond (3-4s) are all perfect options for newcomers and intermediate lash technicians. Despite its slow drying time, Lady Bond is the most popular slow-drying adhesive as it can function well in all seasons and humidity. 

How to use glue step by step ?

Step 1: Remove the cap, place the glue pin in the nozzle.Step 2: Shake vigorously for 1 minute before use so that all ingredients are well blended.Step 3: Pour enough of the desired glue onto the lash jade stone.Step 4: Grab a small bead of glue on the extension and place immediately onto the natural lash. DO NOT paint, or swipe.Step 5:  Burp the adhesive after each use to avoid air bubbles.

What are pro tips for using adhesive?

- Retention can be up to 7 weeks under proper application and aftercare. That means you should always remember to use primer/booster and super bonder to keep the best retention.- Replace glue drop every 10-15 minutes since the glue will react with the humidity in the air, which will become stringy then lower the glue’s performance.- Product must only be used on completely closed eyes throughout the application to avoid eye irritation.- Dip the lash in the middle of a glue droplet since it dries from the outers.- Use under eye gel patches or medical foam tape to minimize fumes.- Products must be used in a well-ventilated work environment and free from exposure to direct sunlight.- Patch test is required before using this product. Different adhesives have different % of ingredients.- Read proper instructions on the back of the label before use.- During hotter weather or higher humidity, we recommend that you may want to instead dispense glue onto a shiny surface such as the removable backing tape of the under eye gel pads, this will limit the amount of moisture absorbed from the tape and prevent it curing too quickly on your jade stone/glue ring.

Which kinds of adhesive are the most  suitable for me ?

The best lash adhesive for you will depend on various factors such as your levels, the humidity and temperature in your working room. 

  • Regarding levels, you will need to know how long it takes you to apply a lash extension to a client's natural eyelashes after you dip it into the adhesive. As beginners, you will be looking for kinds of adhesive which have slow drying time such as Ultra Blooming Adhesive, Blooming Adhesive, Supreme Adhesive and Lady Bond Adhesive. In contrast, advanced lash technicians will be looking more at fast-drying adhesive such as Ultra Adhesive, Premium Adhesive, Ultra Volume Adhesive or Volume Adhesive
  • Regarding temperature and humidity, you will need to know your room temperature and humidity by using a hygrometer to keep an eye on your typical room conditions.

How to deal with retention issues ? 

You certainly have heard many claims about poor retention when your client’s eyelash extensions start falling out after a few days. You should always remember that adhesive retention can be up to 7 weeks under proper application and aftercare so please follow these tips to assure that your client’s lash extensions last as long as possible 

  • Make sure natural lashes are cleaned very well prior to the treatment. Use Lash Shampoo and Protein Remover Pads to clean the eye area from any makeup, dust and oils. 
  • Prepare the natural lashes using Protein Remover and then Primer. While Protein Remover will clear the residues and oils, primer will help to open the cuticle of the natural lashes and improves the adhesive bonding power. Moreover, Primer also speed up the drying time of adhesive
  • Work with a glue that is suitable for your experience and work conditions. Remember that incorrect working room conditions with the adhesive can cause poor retention. The best temperature for adhesive  is 18-22°C and humidity conditions being 45-60%. If your:
  • Temperature is lower than 18°C, glue may be drying slower.
  • Temperature is higher than 22°C, glue may be drying quicker.
  • Humidity is lower than 45%, glue may be drying slower.
  • Humidity is higher than 60%, glue may be drying quicker.
  • Make sure that your attachment is always spot on, which means there is enough glue to hold the extensions and that the base of the lash extension (at least 2mm) is fully attached to the natural eyelashes
  • Always work with a fresh adhesive drop and shake the adhesive bottle vigorously for at least 1-2 minutes before each use. Ensure your adhesive is stored correctly (Humidity: Less than 40-45%, Temperature: 8-13°C)  and is not out of date 
  • Use super bonder at the end of lash application to keep the best retention. Superbonder adds elasticity to the adhesive for better retention and helps to increase the curing time.
  • Make sure your clients are following the aftercare advice and are not picking the lashes and are keeping them clean. 

Please note that there are some other reasons which result in poor retention such as heaters and seasons of lash shed 

  • In the periods of natural lash seeding such as Spring and Autumn, natural lashes start falling out so your clients might experience a loss of both natural lashes and lash extensions
  • In cold places or in winter seasons, many clients use heaters in their room which cause an increase in temperature. It is also a factor that affects retention.

What is the shelf-life of adhesive?

A bottle of glue can last up to 6 months unopened. Once opened, the expiration date is one month only. To keep an eye on the freshness of your adhesive, simply stick a piece of tape with a written date when you open your adhesive bottle. 

Is the adhesive Latex- free and Formaldehyde-free?

Yes!  All of our adhesives are latex-free and formaldehyde-free

Which certificates do you have for adhesive?

We have an MSDS, test reports and SGS certificate. For more information, please leave us question via email [email protected] 

Are your adhesives oil-free or oil-resistant?

All of our adhesives are resistant to naturally occurring oils such as sebum.  It is still never a good idea to put oil on or around your lashes.

How often is a new drop of adhesive needed?

It is essential to replace glue drop every 10-15 minutes since the glue will react with the humidity in the air, which will become stringy then lower the glue’s performance.

Which glue is suitable for sensitive eyes ?

  • In case clients who have sensitive eyes and they feel uncomfortable with strong fumes, we recommend using low-fume adhesives such as Ultra Adhesive, Supreme Adhesive and Lady Bond Adhesive. Also, please remember to use Super Bonder at the end of lash application to reduce the fumes OR use Glamcor Flow to extract the adhesive strong fumes and improve the quality of air
  • All our adhesives contain the same active ingredient which is cyanoacrylate. Cyanoacrylate is the major component of all professional lash adhesive and holds accountable for bonding. However, the fume of cyanoacrylate is the main reason for most allergic reactions. That is why we do not recommend using adhesive on clients who have experienced allergy. 

How do I store my adhesives?

  • For unopened adhesive bottles, we recommend to store it in a refrigerator (Humidity: Less than 40-45%, Temperature: 8-13°C)
  • After opening
  • Adhesive bottles must be stored correctly in a well-ventilated, dark environment and are free from exposure to direct sunlight or heaters. 
  • Always clean and wipe the nozzle after use before putting the cap on. 
  • Change out nozzles as needed to keep the cap and nozzle clean.
  • Always putting adhesive bottles into a pouch with Silica gel or Adhesive Container to protect from humidity 

Can you omit the carbon black from the adhesive?

Yes we can. Actually carbon black is responsible for the deep black color of glues. It is the heaviest ingredient and sits at the bottom of the bottle when not shaken. That’s why if we remove carbon black from the ingredients, the color of adhesive is transparent and you often call this kind of adhesive as “Clear or Invisible Adhesive” 

Which scents can you customize for adhesive?

We can customize 3 scents, including banana, pineapple and vanilla. The drying time for scented adhesives are all 1-2 seconds and highly recommended for advanced lash artists

Can I use lash adhesive for DIY lashes ? 

This adhesive is meant for Salon Use Only or Professional who has gotten a lash artist certificate. Please Never use it for Self-Application or with clusters or strip lashes! 


What is the difference between Protein Remover and Primer?

Our protein remover is used to removes oils, proteins, residues left on eyelashes after using Cream Remover and Shampoo while primer’s main function is to moisturize natural lashes, increase drying time of adhesive and neutralize pH levels to improve the bonding between the natural lashes and the extensions.It is highly recommended to use Primer after Protein remover. The reason is because the protein remover is very drying on the lashes and the lash adhesive will not be able to cure without moisture. That’s why we need primer to moisturize the natural lashes 

Is the lash protein remover different from cream or gel remover ? 

Protein remover is different from cream and gel remover. Cream remover and Gel remover are especially designed to help to remove bonded lashes without damaging the natural lashes while protein remover is used to removes oils, proteins, residues left on eyelashes after using Cream/Gel Remover and Shampoo 


What is the pH of primer?

The pH of primer is 7-8 which is safe for even sensitive eyes

What is the difference between primer and super bonder?

Primer is designed to be used at the beginning of the extension application to get rid of makeup residue, protein and oils from natural lashes. A bonus feature is that it accelerates the drying time of glue, allowing for faster, more effective application.This product also helps to moisturize natural lashes then create a perfect bond between natural lashes and the extensions, as the result improving glue attachment and extending the retention. In addition, it also enhances natural lash growth and recovers damaged lashes, keeping them nourished and strong.Meanwhile, Superbonder adds elasticity to the adhesive and is used at the end of the lash application. The additional flexibility ensures the bonds don't break as easily, hence resulting in better retention. Another function of Superbonder is that it can instantly polymerise the glue, without shock curing. Super Bonder also can lock in the fumes from the adhesive and with the fumes contained, irritation and sensitivity are significantly reduced. Additionally, because the bonds have been sealed, the lashes are instantly safe to get wet. Therefore, your clients don’t need to wait 24 hours after the treatment!

Which scents and colors can you customize for Cream Remover?
