Inside the Formula

When it comes to nail gels, most people think only about colour and shine. But at Sasi Girls, we believe beauty should never come at the expense of your health. That’s why our gels are proudly TPO-free — and even more importantly, powered by next-generation curing technology.


What Is TPO?

TPO (Trimethylbenzoyl Diphenylphosphine Oxide) is a chemical commonly used in gel nail products to help them cure under UV or LED light.

The problem? TPO has been linked to skin irritation, allergic reactions, and long-term sensitivity. While it gets the job done, it’s an outdated ingredient that doesn’t align with modern beauty standards of safety and care.


What Makes Sasi Girls Different

Instead of relying on TPO, we’ve chosen advanced photoinitiators such as Ethyl Trimethylbenzoyl Phenylphosphinate and Hydroxycyclohexyl Phenyl Ketone.

These sound technical, but here’s what they mean for you:

  • Gentler on your skin – fewer risks of irritation or allergic reactions.

  • Smarter curing – flawless results under UV/LED without compromise.

  • Long-lasting luxury – high-gloss, salon-quality nails that are safer for everyday wear.

In short, we’ve replaced outdated chemistry with innovation, giving you the confidence of safe beauty without sacrificing performance.


More Than Just TPO-Free

Our promise goes further than removing one ingredient. Every Sasi Girls formula is:

  • 12-Free – no toxic chemicals like formaldehyde, toluene, or parabens.

  • Vegan & Cruelty-Free – because beauty should never harm animals.

  • Crafted with Premium Imported Raw Materials – ensuring salon-quality shine and durability from home.

This is beauty that’s clean, conscious, and undeniably chic.
