Apex, Explained
Quick definition
The highest point of a structured enhancement, placed over the stress area for strength.
A well-built apex sits slightly behind the center of the nail plate, distributing force so extensions flex instead of snap. No apex means the set will crack at the smile line within days.
It's invisible when done right and the entire secret of durable long nails.
