3-Free Builder Gel (HEMA, TPO & HPMA-Free)
Stellar Gel 3-Free is a self-leveling builder gel system formulated without HEMA, TPO or HPMA.* Those are the three ingredients most often linked to sensitivity in gel. Made in the USA, professional only, and built by a working nail tech.
Builder gel, BIAB, structure gel: the same job under different names. Stellar's 3-Free line covers all of it, with nine builder gels across four systems plus the bases and top coat that go under and over them.
The four builder gel systems
- Structure Gel 2.0: our soft builder gel in a bottle (BIAB). Thin viscosity, enhanced self-leveling, primer and base built in. Soak-off. Clear, Blush Veil and Pink Petal. 18 ml.
- Structure Gel: the original formula, slightly thicker than 2.0. Self-levels for durable overlays and short-to-medium extensions. White. 18 ml.
- Hard Structure Gel: 1-step builder that self-levels quickly and cures to a high shine, top coat optional. Clear and Blush Veil. 30 ml jar.
- Hard Structure Fiber Gel: milled fibers encapsulated for maximum strength on medium-to-long extensions. Clear, White and Rose Petal. 30 ml jar.
The rest of the system
Rubber Base 3-Free works as a base coat or a lightweight structure gel in one bottle, ideal for thin and brittle nails. Stellar Bond Base 3-Free is our acid-free primer, and Stellar Shine Top 3-Free seals the set. The line also includes 3-Free colours across crèmes, cat-eyes and glass gels.
