Care & Tips

Refillable products are changing the way we shop for home fragrance and self-care, and for good reason. From luxury candle refills and reed diffuser refills to refillable bath & body essentials, choosing refills is one of the simplest ways to reduce waste without compromising on quality.

At True Grace, we believe sustainability and luxury should work together beautifully. Our refill collection is designed to help you reuse the vessels you already love, minimise unnecessary packaging and enjoy the same signature fragrances with a lighter footprint.

If you’re wondering how refills work, whether candle or diffuser refills are right for you, or why refillable products are more sustainable, you’re in the right place.

Why Choose Refills?

Refilling is a small shift that makes a meaningful difference over time.

When you choose refillable candles, diffuser refills or bath & body refills, you:

  • Reduce single-use packaging
  • Extend the life of your favourite vessel
  • Lower your environmental impact
  • Shop more consciously without sacrificing indulgence

Our diffuser refills are bottled in 100% recycled PET, and all refill packaging is fully recyclable through standard kerbside recycling, making it easier to make a more sustainable choice.

It’s not about doing everything perfectly. It’s about choosing better, where you can.

Candle Refills

Luxury candle refills allow you to reuse your existing candle jar while enjoying the same beautifully crafted fragrance and premium wax blend.

How do candle refills work?

Candle refills are designed to fit inside your original vessel once it’s been cleaned and prepared. Simply remove any remaining wax, place the refill inside and enjoy the glow all over again.

For a full step-by-step guide, read our detailed article on how to use candle refills.

Are candle refills better for the environment?

Yes! Refillable candles reduce the need for new jars and excess packaging, helping to lower waste and material usage over time.

They’re ideal if:

  • You love the ritual of lighting a candle
  • You enjoy a warm, atmospheric glow
  • You want a sustainable alternative to replacing the entire product
Diffuser Refills

Reed diffuser refills offer long-lasting fragrance without the need to replace the entire bottle.

How long do diffuser refills last?

A quality diffuser refill can last several weeks to months, depending on room temperature, airflow and how often the reeds are turned.

Are diffuser refills more sustainable?

Our diffuser refills are bottled in 100% recycled PET and are fully recyclable after use. By reusing your original glass vessel, you significantly reduce waste compared to buying a completely new diffuser each time.

They’re perfect if:

  • You prefer continuous fragrance without a flame
  • You want low-maintenance scent
  • You’re scenting hallways, bathrooms or workspaces
Bath & Body Refills

Refillable bath & body products bring sustainability into your everyday routine.

Instead of replacing your bottle each time, simply top it up with a refill pouch or bottle — reducing packaging waste while keeping your bathroom beautifully stocked.

Are refillable toiletries hygienic?

Yes, as long as the original bottle is rinsed and dried before refilling, refillable bath and body products are just as safe and effective as buying new.

They’re ideal if:

  • You go through hand wash or body wash regularly
  • You want to reduce plastic waste in your bathroom
  • You prefer consistent fragrance and formulation
Candle or Diffuser: Which Is Best for You?

It depends on how you like to scent your space.

Choose a Candle If:

  • You enjoy the ritual of lighting and extinguishing
  • You want ambience and soft lighting
  • You tend to scent living rooms or bedrooms

Choose a Diffuser If:

  • You prefer constant fragrance
  • You don’t want an open flame
  • You’re scenting smaller or high-traffic areas

Many of our customers use both; candles for atmosphere in the evening, diffusers for effortless daytime scent.

There’s no wrong choice. Just different ways to enjoy fragrance.

Frequently Asked Questions About Refills
What are luxury refills?

Luxury refills are replacement inserts or top-ups designed to fit into your existing candle jars, diffuser bottles or bath & body containers, allowing you to reuse the original packaging.

Are refills cheaper than buying new?

Refills can offer better value over time, as you’re not paying for a new vessel each time, while also reducing waste.

How do you clean a candle jar for a refill?

Allow the wax to cool fully, remove any remaining wax and wick base, and gently clean the jar before inserting your refill. See our full guide above for detailed instructions.

Why are refillable products more sustainable?

Refillable products reduce the need for new materials, lower packaging waste and encourage longer product lifecycles, making them a more environmentally conscious choice.
