The SteelFit Difference

Smoother Looking Skin, Less Visible Cellulite

Buns of Steel combines targeted skin-conditioning ingredients with a warming formula to help improve the look of skin texture, firmness, and the appearance of cellulite on the glutes and thighs.

01

Visibly Lifts, Firms & Defines

Buns of Steel® delivers results you can feel and see. It helps bring out your natural muscle tone, reduce the look of dimpled skin, and firm up where it matters most.*

02

Smooths Skin & Reduces the Appearance of Cellulite Dimples

Formulated with Regestril™ and Keratoline™, Buns of Steel® improves elasticity and softens uneven texture over time. It’s the go-to cream for smoothing stubborn areas, reducing the look of stretch marks, and boosting skin confidence.

03

Clinically Studied Ingredients

In a study where women applied 4% Intenslim twice daily for 2 months days, the subjects decreased fat thickness by 24% and circumference and volume by up to 2.77 cm. That’s a dress size!*

What's inside

Ingredient breakdown.

Every key ingredient and the job it does.

01

Intenslim

Intenslim is a specialized active designed to help reduce the visible signs of cellulite and improve skin firmness. It works to target fat storage areas, promoting a more sculpted and contoured appearance.

02

Globularia Cordifolia Extract

This botanical extract helps protect the skin from environmental stressors and supports a more even, youthful appearance. It promotes a healthy skin barrier and a smoother look and feel.

03

Zerumbet Extract

Zerumbet, derived from ginger flower, helps stimulate circulation and supports firm, toned skin. It’s often used in body-contouring formulas to help smooth the appearance of cellulite.

04

Keratoline

Keratoline is an enzymatic exfoliant that helps smooth and soften the skin’s surface. By gently removing dead skin cells, it allows active ingredients to penetrate more effectively and enhances overall skin texture.

05

Caffeine

Caffeine is a natural stimulant that helps increase circulation and support the breakdown of stored fat beneath the skin’s surface. When applied topically, it can help tighten and firm the appearance of the skin, giving it a smoother and more toned look. It’s a key ingredient in targeted firming products because it delivers fast-acting, visible results.

06

Regestril

Regestril is a clinically studied complex that helps reduce the appearance of stretch marks and improves skin smoothness. It works by supporting skin regeneration, helping to restore firmness and resilience over time.

A note from Rob

Why we made Buns of Steel.

Buns of Steel® has always been about more than just looks. It’s about confidence and helping you feel strong in your own skin. I wanted to create something that supports your lower body goals and helps tighten and tone where it counts. Made with clinically studied ingredients, it delivers real results you can see and feel.

Questions, answered.

Does Buns of Steel Actually Work?

Yes! Buns of Steel's main ingredient Intenslim has been shown in human studies to help decrease fat thickness, circumference, and volume in women. In a study where women applied 4% Intenslim twice daily for 2 months days, the subjects decreased fat thickness by 24% and circumference and volume by up to 2.77 cm. That’s a dress size!*

Why does Buns of Steel tingle and burn?

Buns of Steel contains heat-generating compounds to help the active ingredients penetrate deeply into the hypodermis and target your existing body fat. Many people also find this helps create a “mind-muscle connection” that is helpful during leg and glute-focused workouts. Don’t worry: this sensation is temporary and harmless!

When should I apply Buns of Steel?

For best results, we recommend applying Buns of Steel twice per day for at least 4 weeks. Many customers tell us they prefer to apply once before a workout, and then again before bed.

Does Buns of Steel Work Without Thigh Trimmers?

Yes, Buns of Steel’s active ingredients work without having to wear a thigh trimmer. But wearing a trimmer will increase circulation and body heat around your legs, helping Buns of Steel penetrate deeper into the sub-dermal layer.

Do I have to have a low body fat percentage?

No! Buns of Steel can help smooth and firm the look of your skin at any stage.*

Can men use Buns of Steel too?

Yes! All of the active ingredients in Buns of Steel work just as effectively for men as women.
