What is a sealer for eyelash extensions?

Eyelash extension sealer is a specialized product used in lashes extensions. They are designed to apply a layer to individual lash extensions. This sealer performs a role similar to top-coat nail polish for a manicure.  It acts as a barrier that helps the eyelash extensions avoid contact with external factors like dust, oils secreted naturally from your body, humidity, and moisture that can compromise the adhesive bond and lead to premature lash shedding. This protective effect keeps the lashes fresher, ensures better retention of the extensions and helps to prevent them from twisting.

Benefits of Using an Eyelash Extension Sealer

When talking about the benefits of eyelash extension sealer, the first thing to mention is that it prolongs the lifespan of lash extensions. As we mentioned before, by creating a protective barrier around individual lashes, the lash adhesive is shielded against environmental factors, allowing them to last longer. Additionally, using a sealer reduces the need for frequent lash touch-ups. Clearly, reducing the impact on the lashes contributes to their durability.

Furthermore, although the eyelash extension sealer creates a thin coating over the lashes, it does not affect the curl or thickness of the extensions. Instead, it helps maintain the curl and shape of the lash extensions. Using a sealer ensures that the lashes do not droop or lose their soft, gentle appearance.

Some types of eyelash extension sealers also provide a glossy and metallic effect for the lashes. This adds sparkle and enhances the overall look of the lash extensions, making them more attractive.

Moreover, the sealer for eyelash extensions can help reduce irritation for the eyelids and the surrounding eye area. It can prevent discomfort or itching caused by debris accumulating on the lashes.

Types of Eyelash Extension Sealer

There are primarily two types of eyelash extension sealer: coating sealers and adhesive sealers.

  • Coating Sealers: These sealers form a protective layer over the lash extensions. They come in clear or black varieties and can provide a slight sheen to enhance the lashes’ appearance. Coating sealers are usually applied to the lashes after extension application to add an extra layer of protection and shine.
  • Adhesive Sealers: Unlike the coating sealer, the adhesive sealer only covers the attachment points and does not create a layer over the entire lash extensions. It is specifically used to strengthen the bonds between your natural lashes and the lash extensions. After using eyelash glue to attach the false lashes to your natural lashes, a lash technician may apply this adhesive eyelash extension sealer to the contact points to enhance the adhesion of the eyelash extensions. Therefore, the main function of this sealer is to ensure that the lash extensions remain in place for a longer period.This adhesive sealer comes in both black and transparent varieties. The black option not only reinforces the lash bonds but can also enhance the color effect of the eyelash extensions.

Even Though there are some differences in its own functions, both types of sealers play essential roles in maintaining the quality and durability of eyelash extensions, ensuring they remain intact and looking beautiful for an extended period

Q1: When is the suitable time to begin applying eyelash extension sealer?

It is advisable to begin using the eyelash extension sealer after 2 to 3 days from the treatment. This precaution is necessary as the eyelash extension adhesive may still be in the curing phase even after 24 to 36 hours, and using the sealer too soon could potentially cause a blooming effect.
