By adjusting the pH level of the natural lashes to pH 7 with this primer, the extension glue sticks tighter and faster and the application procedure is easier.
There are various types of lash cleaners such as alkaline or acidic pH types.
If the natural lashes become alkaline, the cuticles will open easily, which may cause the adhesive to get into the peeled cuticles and make it difficult to provide good retention. Alkalinity also causes the adhesive to shock-cure.
So, I always use this product before procedures to prevent damage and to give better retention.
