About Giusto Beauty
Beauty should never compromise health.
Giusto Beauty was founded by Jamie Justo, a licensed esthetician with over 13 years of professional lash and brow experience. After watching countless artists struggle with harsh chemistry, damaged client lashes, and ingredient labels that read like a warning, Jamie set out to build something different.
Why we built BOOST
Most lash lift systems on the market still rely on ammonium thioglycolate, sodium bromate, ethanolamine, and synthetic fragrance — ingredients with known irritation potential and well-documented hair damage. They work, but they come at a cost.
BOOST is the first lash lift and brow lamination system formulated with EWG green-grade raw materials and built around pure cysteamine — scientifically proven to have the lowest cytotoxicity of any lifting compound on the market. The result: a damage-free lift that’s gentle enough to use even at the tips of the lashes, with results that hold longer than traditional chemistry.
Built for licensed professionals
Every BOOST Kit ships with our complete online certification course at no additional cost — because clean-beauty chemistry without proper training doesn’t help anyone. We also offer in-person 1:1 and small-group training in San Diego, plus a Train-the-Trainer program for advanced certified professionals who want to teach in their own communities.
The Giusto promise
- EWG green-grade raw materials in every product
- Free from thioglycolate, ammonia, sodium bromate, parabens, ethanolamine, and synthetic fragrance
- Vegan and cruelty-free
- Made for licensed professionals, with the consumer in mind
