What should be avoided during the first 24 hours after an eyelash extension application?

Avoiding water exposure during the first 24 hours after an eyelash extension application is crucial because it allows the adhesive used to bond the extensions to your natural lashes to cure properly. Water can interfere with the setting process, potentially weakening the bond and leading to premature shedding of the extensions.

Within this timeframe, it's essential to keep the lashes dry to ensure a strong and durable hold. The adhesive typically reaches its optimal strength after this initial period, making it important to refrain from any activities that may introduce moisture to the lashes, such as swimming or steam exposure.

While heavy makeup can be problematic, as it may require thorough cleaning of the eye area, and sleeping on your back may also impact the retention if your lashes come into contact with bedding, those factors are secondary to the immediate concern of water exposure affecting the adhesive's performance. Using a fan is generally acceptable and can even help in drying the adhesive quickly.
