Description

Top up your favourite deodorant with our convenient, letterbox-friendly refill bars now available in all scent and formula variations. 

Each bar is a generous 60 grams - that’s twice the size of most stick deodorant refills - designed to fill your jar to the brim and last around 3 months with daily use.

Simply snap off a piece, press it into your jar using clean fingers or the back of a teaspoon, and you’re all set.

Got a little extra on your hands? Rub it straight onto your underarms—you’re fresh for the day.

Packaged in glassine paper that’s recyclable and home compostable for a simple, low-waste refill.

Less waste. More freshness. Always Simply Effective.

Which Formula?

Classic Formula: Combines bicarbonate of soda and magnesium for powerful odour protection that lasts all day. It’s our go-to blend for most skin types, offering reliable freshness with clean, effective ingredients.

Sensitive Formula: Designed for delicate skin. It’s bicarb-free and uses a higher dose of magnesium to neutralise odour gently—without compromising performance. Perfect for those who prefer a milder touch but still want long-lasting results.

I don’t usually go for reviews but I’ve been using Simply Effective for around 4/5 years and can honestly say I’ll never go back to any other deodorant. The new limited edition coco-sandlewood scent is just perfect for Summer!

How long does each tin last?

Each 5g mini tin will last around 1–2 weeks with daily use. A little goes a long way!

Yes! Every single scent we offer is available in both formulas. Whether you're choosing a full-size jar or one of our eco-friendly refill bars, you'll be able to select the Sensitive option if that's what your skin prefers.

Can I reuse the tins?

Absolutely. Our tins are fully recyclable and reusable, ideal for travel or storage.

Can I travel with these?

Yes! They’re the perfect size for handbags, gym bags, hand luggage, bum bags etc.
