I am Sara Kim, a licensed nail technician with 8+ years behind the table. If you are new, start with the Builder Gel Nails guide to see how I explain technique, safety, and product choice. Everything on this site reflects real salon experience, not generic AI content — and this page explains exactly how that promise is kept.

Who I Am

  • Licensed nail tech with eight years in salon and studio environments
  • Specialize in builder gel, BIAB, and structured manicures
  • Safety-first approach: clean prep, proper cures, and gentle removal
  • Every article on this site carries my byline, and my author page lists all of them

How I Test Products

  • I apply each builder gel on real clients and practice tips before recommending it.
  • I track viscosity, self-level speed, brush feel, and cure times under a 48W LED lamp I have owned since 2023, so cure numbers are comparable across reviews.
  • I note reactions on sensitive clients and prefer HEMA-free options when needed. The American Academy of Dermatology's overview of contact dermatitis is the reference I point clients to when a reaction shows up.
  • I compare wear after 2 to 3 weeks, watching for lifting, cracking, or discoloration, and I log the day a set fails rather than rounding up.
  • Products I have not personally applied are described as such; a "best" list on this site never includes a product I have only read about.

Editorial Principles

  • Accuracy over hype: if a formula needs 120 seconds to cure, we say it.
  • Safety first: prep, skin avoidance, and safe removal are always emphasized.
  • No pay-to-play: brands do not buy placement or ratings, and no brand sees an article before it is published.
  • Regular updates: cure times and best practices change; we update accordingly and show the real "Updated" date on each page.

How Articles Are Produced (Including AI)

Articles on this site are researched and drafted with AI assistance, then edited by me before publication. The AI does the tedious part — collecting brand cure charts, organizing an outline, tightening prose. What it cannot do is the part that matters: the wear-test results, the dated anecdotes from the chair, the product verdicts, and the corrections when a formula changes. Those are mine, and I take responsibility for every published claim. If an article reads like it was written by someone who has never held a builder gel brush, that is a bug, and I want to hear about it.

How This Site Is Funded

Some links are affiliate links. When you buy through them, we may earn a commission at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. This does not change our verdicts; it keeps the site running while we remain independent. Product prices shown on the site are pulled from Amazon's product data and refreshed daily, with the "as of" date shown under each product block — if a price looks off, Amazon's page is the source of truth.

We do not sell sponsored posts, and we do not accept free product in exchange for coverage. If that ever changes, this page will say so first.

Corrections and Updates

  • When a reader or a brand points out an error, I verify it against the product and fix the article, then update its visible "Updated" date.
  • Cure times are re-checked whenever a brand reformulates or when I change lamps, and the affected pages are revised together.
  • Old guides that have been merged into newer ones redirect to the current page rather than lingering as duplicates.

Key Mistakes We Avoid

  • Publishing untested claims about cure times or product performance.
  • Recommending products without noting viscosity, brush feel, and allergy considerations.
  • Allowing affiliate revenue to overrule safety or honesty.
  • Leaving content stale; we revisit articles when formulas or best practices change.

Final Note from Sara

Builder gel nails should feel like a protective shell, not a gamble. Thanks for trusting me with your nails. If you need the full foundation again, return to the Builder Gel Nails guide and start from the basics, or browse the buyer's guides when you are ready to choose a product.
