If lash adhesive leaves a white residue, it typically means that the adhesive has not fully dried or cured. When the adhesive is applied to the lash band, it needs time to dry and create a strong bond. If the adhesive hasn't fully dried, it can leave a white residue on the lashes or skin. This residue is often visible and can be unsightly.
There are a few reasons why lash adhesive may not fully dry or cure. First, it could be due to the type of adhesive used. Some adhesives dry faster like iLevel Lab Non-Shake Volume Adhesive, and some may require a longer drying time such as iLevel Lab Mrs. Bond Adhesive, depending on the humidity or temperature in the room. Second, the amount of adhesive applied can also affect drying time. Applying too much adhesive can cause it to take longer to dry or not dry at all. Finally, applying lashes too quickly after the adhesive is applied can prevent it from fully curing.
To prevent white residue from lash adhesive, make sure to use a high-quality adhesive that dries clear and is suitable for your skin type. Be sure to follow the instructions provided by the adhesive manufacturer, including the recommended drying time. Additionally, use a small amount of adhesive, and allow it to dry completely before applying lashes.
