Interview with the Nail Chemist 🧪 Part 3 | Why Gels Are Failing (TPO Ban, Primers, Press-ons & More)

In Part 3 of this interview series, polymer chemist Gea Lukic and I discuss the chemistry changes reshaping the industry. We dive into the science behind the recent TPO bans, alternative photoinitiators, how acid versus acid-free primers really interact with keratin, and the physics of light behavior in glitters and pigments. We also explore salon safety, dust hazards, the reality of wearing press-ons with uncured products, and how to build a thoughtful, safe kit without over-consuming. ✨ Follow Gea Lukic: YouTube: @thenailschemist Instagram: @thenailschemist (English) | @gealukic (Croatian) TikTok: @gealukic (Croatian) Products I Use: https://www.amazon.com/shop/nailnarra... 💖 Support The Channel 💖 You can support my channel by using my Amazon storefront link above to make purchases at no extra cost to you!
