Stonhart Promo Codes — Up to $299 OFF June 2025

Two licensed estheticians founded Stonhart with the intention of providing pros in the aesthetic industry with high-quality products, education, and new ideas. Stonhart set out to launch their first product line more than four years ago. Finding a them lab that could produce adhesive for lash extensions that is both safe and effective was their initial objective. They spent a lot of time looking before they found their ISO-certified, FDA-registered lab with skilled chemists and launched their first product, their well-liked lash extension adhesive. Since then, they've expanded into skincare, brow henna, and lash and brow lifting products through their network of manufacturers, bringing quality to all product categories.
