Step 1- Preparation

You will be asked to remove your contact lenses and your makeup. Once your skin and eye area is clear, your eyelids and eyelashes will be degreased using a fibre-free applicator soaked in a primer.

Step 2- Application

The thinner part of the fake eyelash is dipped in glue with a tweezer attached to the natural lash. It can be done by attaching false eyelashes from the bottom, the top or from the side.

Make sure that the adhesive is distributed by swiping the fake eyelash along your natural eyelash a few times.

It is important to set the false extension on the natural lash at least 1 mm away from the eyelid.

Step 3- Drying

A pump may be used to speed up the drying process. Now, make sure no two fake eyelashes or natural eyelashes are stuck together. Use a tweezer to segregate any extensions from neighboring lashes.

Do not try to pull or seperate in a vertical manner, do it in a horizontal manner.

Let dry, spray some distilled water, wait till it dries again and perform another round of segregation.

Now that you’re done with your eyelash extension process, avoid touching the lashes for 24 hours to allow the glue to fully dry and make sure they don’t get wet during that 24 hours either.
