The gap

WHY CELLULITE CAN STILL SHOW

Cellulite is influenced by connective tissue, skin firmness and the shape underneath — not simply body fat or how hard you train.

Connective tissue
01

Connective tissue

Fibrous bands connect the skin to the tissue underneath. The way fat and connective tissue interact can create the uneven surface we recognize as dimpling.

Skin firmness and Elasticity
02

Skin firmness and Elasticity

When skin becomes thinner or less elastic, the structures underneath can become more visible. Hormones, age and changes in body composition can all influence how the surface looks.

The Shape Underneath
03

The Shape Underneath

Building the glutes and hamstrings can improve the shape beneath the skin. It will not remove cellulite, but more muscle can help the area appear stronger, fuller and more defined.

    The Straight answer

    What it does, What it doesn't

    Most creams promise things no topical can deliver. Here’s the truth: Buns of Steel® supports how the skin looks and feels — it does not replace the work happening underneath it.

    What it does

    • Delivers 4% Intenslim™, the level evaluated in clinical studies
    • Includes Regestril™ to support the appearance of stretch marks
    • Uses Keratoline™ to gently exfoliate and smooth the skin’s surface
    • Supports smoother, firmer and more toned-looking skin with consistent use

    What it doesn't

    • Permanently remove cellulite
    • Replace training, nutrition or weight loss
    • Lift, enlarge or reshape the glutes
    • Produce overnight or identical results for everyone

    What's inside

    WHAT MAKES THE FORMULA WORK

    The formula combines 4% Intenslim™ with targeted firming, smoothing and exfoliating ingredients for the glutes, hips and thighs.

    01
    Intenslim

    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

    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 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

    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

    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

    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.

    How to use

    Twice a day,
    Give it time

    Apply consistently twice daily. The clinically studied research behind Intenslim™ evaluated two months of use, so think of this as a body-care routine — not an overnight fix.

    1
    Apply to clean, dry skinMassage a thin, even layer over the glutes, hips and upper thighs. Avoid broken skin and sensitive areas.
    2
    Massage firmly until absorbedUse circular motions until the product has absorbed. A warming or tingling sensation may occur.
    3
    USE MORNING AND EVENINGApply twice daily, including on non-training days. Allow the product to absorb before getting dressed.
    Pair it with lower-body trainingResistance training builds the shape underneath, while Buns of Steel® supports how the skin over it looks. Applying before training can also enhance the warming experience.

    FAQ

    What women ask before they buy

    Will this get rid of my cellulite?

    No topical can permanently remove cellulite because it is influenced by the structure beneath the skin. Buns of Steel® is designed to improve its appearance by supporting firmer, smoother and more hydrated-looking skin. The Intenslim™ supplier study evaluated twice-daily use for two months, and individual results varied.

    Do I have to be lean for it to work?

    No. Cellulite appears across a wide range of body types and fitness levels. Buns of Steel® can support smoother, firmer-looking skin wherever it is applied, regardless of where you are in your journey.

    Why does it tingle and warm up?

    The formula can create a temporary warming or tingling sensation that varies from person to person. Start with a small amount and patch test before first use. Wash the area and discontinue use if the sensation becomes uncomfortable or irritation develops.

    How long until I see something?

    The Intenslim™ supplier study evaluated twice-daily use for two months. Some customers first notice changes in how hydrated or smooth their skin feels, while visible changes may take longer. Consistency matters, and individual results vary.

    Can I use it while pregnant or nursing?

    Speak with your healthcare provider before use while pregnant or nursing. They can advise you based on the ingredients and your individual circumstances

    Will it stain my clothes or sheets?

    No, but let it absorb fully first. It's a non-greasy formula that dries down quickly and won't stain fabric.
