I formulated this because I needed it myself — for my own sensitive, psoriasis-prone skin.
For those who love their tan bold, rich and beautifully bronzed, RBF Cosmetics Ultra Dark Self Tanning Foam delivers our deepest, most intense colour yet. Designed to achieve a flawless, natural-looking ultra dark finish, this lightweight foam develops evenly for a salon-quality tan you'll feel confident wearing.
Created with sensitive skin in mind, the fast-drying formula glides effortlessly onto the skin using an instant colour guide to help achieve streak-free, even coverage every time. The result is an ultra-dark bronze that develops over 4–8 hours, lasts up to 7 days and fades naturally without patchiness or orange tones.
Whether you're a dedicated self-tanner or preparing for a holiday, event or competition, Ultra Dark gives you the confidence of a deep, flawless glow that looks as good as it feels.

The Founder's Promise
I created this because I was tired of fake tan that irritated my own sensitive, psoriasis-prone skin. Every formula exists to solve a real problem — mine, and hopefully yours too.

Build Your Routine
The RBF tanning mitt is essential for a streak-free result — it's the same tool Janice uses with every professional client, included in every routine below.
No — RBF tanning foams are formulated for a natural, no-orange colour and are designed to apply evenly without streaking when used with our tanning mitt. Every foam includes a colour guide so you can see exactly where you've applied it.
No — once developed, RBF tanning foam won't transfer onto clothing or bedsheets. We recommend loose, dark clothing for the first few hours after application while the colour guide washes away.
Medium suits first-time tanners and fair-to-medium skin tones; Dark suits medium-to-olive tones wanting a deeper colour; Ultra Dark suits those wanting maximum depth. See our Shade Guide for full detail.
Yes — our formulas are alcohol-free, paraben-free, and developed through years of real experience with sensitive and reactive skin.
Wait at least 6–8 hours before showering. You can get dressed once the product is dry to the touch (usually within minutes), in loose, dark clothing.
