Bottom Lash Extensions: Procedure, Cost, And Aftercare

Bottom lash extensions are a popular beauty trend that can enhance the natural look of your eyes and give them a more defined appearance. Various lengths, thicknesses, and curls of extensions made of synthetic materials such as mink or silk are individually applied to match your natural lower lashes.

What Are Bottom Lash Extensions?

The eyelash extensions for bottom lashes are typically shorter and thinner than the upper ones. Bottom lashes added length and definition can open up a person’s eyes, making them appear even more significant and dramatic without seeming “fake.” Additionally, bottom lashes reduce the risk of an imbalance from only having upper lashes, especially when worn with eye makeup.

How Do Bottom Lash Extensions Work?

Applying lower lash extensions is similar to upper lash extensions but in the opposite direction. Lash extensions will be applied toward the skin to follow the natural growth of the lower lashes, resulting in the tip of the lash extension curl facing down toward the skin.

With typically fewer lower lashes than upper lashes, the process takes much less time, usually around 30 minutes, and only requires attaching 40-50 extensions to the bottom row to improve the set dramatically.

Bottom Eyelash Extensions Procedure

The lash artist uses tweezers to pick up each extension, coats it in lash adhesive, and adheres it to your natural lashes. One extension is glued to per one natural lash.

Who Can Get Lower Lash Extension?

Everyone can use lower lashes extensions, but the following three clients will adore them more than anyone else.

Mascara Lovers

Some people can’t part with their mascara-boosted lower lashes. Most mascaras are not lash extension friendly and can harm retention, even though we can understand the urge! For people like this, getting lower lash extensions is an excellent option because it reduces the chance of mascara clumping with upper lash extensions.

Mega Volume Lash Clients

The main goal of lash extensions on bottom lashes is to balance the top and bottom lashes. The addition of lower lashes can easily balance the focal point and improve the quality of lashes if she feels like they are a little too dramatic.


This is a huge benefit for brides, who need to look great and are likely to cry a lot. In addition to enhancing their appearance, a bottom eyelash extension can help them avoid embarrassing situations where they appear to have raccoon eyes.

Prepping Before Applying Eyelash Extensions To Bottom Lashes

1. The first step is to pull up the upper lashes, so they don’t interfere with the lower ones. Layer two strips of tape with the adhesive parts facing each other. Leave a small amount of the adhesive side on the ends. If you use tape with a solid adhesiveness to hold the upper lashes in place, you risk unintentionally ripping off the upper lash extensions when you remove the tape.

2. Put the eye pad in place, so you’re applying bottom lashes; the eye pad placement will differ slightly. Because the lower lashes will be visible, apply mascara by placing an eye pad underneath them. The placement will remain the same, but it will be below the lash line so that the bottom lashes rest on top of the eye pad. If you have thick or noticeable eye bags, you can use tape or a soft patch (thinner, stretchier eye pad) under the bottom lashes.

Prime The Bottom Lashes

Bottom lashes touch our faces more directly than upper lashes do. They are more susceptible to the effects of facial oil. Use a lash primer to prime the lower lashes. Lower lashes are primed similarly, just like upper lashes.

Which Lashes To Use?

To maintain a natural appearance, bottom lashes should be less curly than top lashes. So for the bottom lashes, a J or B curl should work. Depending on the client’s natural lash condition, the best thickness for a classic lower lash set is between 0.10 and 0.15mm. For a lower volume set, you can also use more lashes (2–3) per bottom lash. Between 5-7 mm is the ideal length for bottom eyelashes. Lashes that are too long may appear overdone.

How To Apply Bottom Lash Extensions

Apply them in the opposite direction (upside down) from how you would apply the top lashes. The tip of the lash curl should be facing the skin when applying the bottom lashes.

As a result, after selecting and flipping your lash extension, you can select the bottom natural eyelash to which you want to apply the extension. The inner corners of the set should always be shorter than the outer corners.

How to Remove Eyelash Extensions?

It is essential to take extra precautions to prevent remover from accidentally getting in the eyes, and because of this, having your extensions removed professionally is always preferable to doing it yourself.

Some steps your lash artist will apply to remove bottom lashes extensions are:

  1. Use a professional eyelash extension remover don’t use home remedies to remove eyelash extensions. They can quickly dissolve the lash glue.
  2. Use an eye pad to protect the skin around the eyes.
  3. Use a lash glue remover.
  4. The lash artist will use tweezers or a swap to remove the extensions after a brief waiting period.
  5. Make sure there is no residue left after taking all the extensions out.
  6. Finally, the lashes will be brushed into place after drying.

How Long Does The Treatment Last?

This procedure is much quicker than the upper eyelash extensions, which take up to 2.5 hours on average. Applying an extension to each bottom lash would be excessive because they are less dense than the upper lashes. 15-20 extensions are sufficient for a more natural effect (some add 30–40, depending on the condition of the bottom lashes). So the procedure usually takes no more than 30 minutes.

How Long Do Bottom Lash Extensions Last?

They only last up to 14 days (2 weeks), which is one of the most significant drawbacks of bottom eyelashes extensions. Since lower eyelash extensions are smaller and more likely to fall off when you rub your eyes or wash your face, they don’t last as long as upper eyelash extensions, which typically last 6 to 8 weeks.

After three to four weeks, it will be necessary to have infills performed to maintain the complete set and prevent it from appearing sparse.

Lower Lash Extension Mapping

For the entire set of lower lash extensions, you can use lash extensions of various lengths. Depending on how you want it, you can achieve either a staggered or a uniform look.

Maintenance Of Bottom Lash Extensions

You must take care of them and fill them up regularly to keep them looking nice. Cleaning or washing the lash extensions regularly is one of the most crucial aspects of maintenance. Sebum, oils, and dust will build up if you don’t, which could cause an infection or harm your natural lashes. Clean lashes carefully with a brush and a specially formulated cleaner like lash foam or micellar water.

Other maintenance advice includes brushing your eyelashes frequently and avoiding products with oils and mascara. Maintenance guidelines for bottom eyelash extensions are more relaxed. You need to be cautious when washing your face around them.

Do Bottom Eyelash Extensions Harm Your Natural Lashes?

Eyelash extensions are usually glued to the natural lashes rather than the skin. The most frequently asked question is whether extensions will harm natural lashes because natural lashes must support the weight of the extensions.

No, if they are correctly done. This calls for the lash technician to carefully consider the extensions’ length, the amount of adhesive they apply, and the condition of the client’s natural lashes. If excessive adhesive or weighty extensions are applied, they might not support the weight and can cause harm.

Can You Use Makeup on Bottom Lash Extensions?

Yes, you can apply makeup to your bottom eyelash extensions just like with your top lashes.
The same advice, such as sticking with water-based makeup, is still valid.

Oil-based makeup is notoriously challenging to take off, and it will damage your natural lash and the lash extension.

Eyelash Extension Aftercare

The aftercare is the same because the bottom and upper eye lash extensions are applied together. It’s not particularly difficult, but keeping your lashes dry for the first 24 hours following the procedure is crucial.

It would be best if you refrained from taking long showers, swimming, steaming, and crying. Avoid oil-based products and eye makeup, especially mascara.

Bottom Lash Extensions Cost

The Cost of lash extensions range from $30 to $100. The price varies according to the number of lashes applied, the salon’s location, and the lash artist’s level of expertise. Keep that in mind if your pricing is based on the number of extensions, as you can anticipate adding between 15 and 30 extensions per eye.

Bottom Lash Extensions – Key Takeaways

Bottom lash extensions make your eyes stand out as if you are wearing subtle eyeliner, although it seems like a small change. They give the eyes a wider appearance and balance between the top and lower lash extension. Although they require some upkeep, the significant impact is worth it. Although they last less time than top lash extensions, it’s not a deal breaker if you love makeup and need them for a special occasion.
