About Us & Editorial Standards
Sara Kim
Licensed Nail Technician & Educator
I’m Sara Kim, a licensed nail technician with 8+ years behind the table specializing in builder gel nails, BIAB, and structured manicures. Every guide on this site reflects real techniques I use on clients—no generic AI filler, no untested claims.
Who I Am
- Licensed nail tech with eight years in salon and studio environments
- Specialize in builder gels (pot and bottle), BIAB, and soft-gel overlays
- Safety-first approach: clean prep, proper cures, and gentle removal
How I Test Products
- I apply each builder gel or BIAB on real clients and practice tips before recommending.
- I record viscosity, self-level speed, brush stiffness, and cure times under a 48W LED.
- I note reactions on sensitive clients and prefer HEMA-free options when needed.
- I compare wear after 2–3 weeks, watching for lifting, cracking, or discoloration.


Editorial Principles
- Accuracy over hype: If a formula needs 120s to cure cleanly, we say it.
- Safety first: We emphasize prep, skin avoidance, and proper removal to protect nail health.
- No pay-to-play: Brands do not buy placement. We cover only products we’d use on clients.
- Regular updates: Cure times, formulas, and best practices change—we update articles as we learn.

Builder gel nails should feel like a protective shell, not a gamble. I publish what works in the salon, adjust when data proves otherwise, and keep safety at the center. Thanks for trusting me with your nails.
