What serves as the primary defense against bacteria in eyelash extension procedures?

Unbroken skin is critical in serving as the primary defense against bacteria during eyelash extension procedures. When skin is intact, it provides a barrier that protects the underlying tissues from pathogens, including bacteria that may be present on the surface. This barrier is essential in preventing infections and ensuring a safe application of eyelash extensions.

Natural lashes, while they do provide some protection by preventing debris from directly contacting the eyelid, do not serve as the primary defense mechanism against bacteria. Eyelash extensions themselves can't defend against bacteria; they can even become a breeding ground for bacteria if not applied or maintained correctly. Water, although it has some cleansing properties, is not a sufficient defense mechanism against bacteria during these procedures.

Maintaining unbroken skin is vital for both client safety and the effectiveness of the eyelash extension process. Proper sterilization practices and hygiene during application also play a significant role alongside the natural protection provided by the skin.
