His Majesty King Charles III's bathing routine made headlines last year after one bath oil got his official stamp of approval with a royal warrant. 

Far from your average bubble bath, the under-the-radar Olverum Bath Oil received the prestigious mark of recognition for its commitment to quality and craftsmanship, supplying goods to royal households for at least five years. And now you can have a bath fit for a king or queen for less, thanks to the W-Wellness exclusive discount code.

If you've ever wondered how the royals unwind or what's in the bathrooms of the royal households, then the chances are you'll find a little bottle of this green bath oil. 

The Olverum Bath Oil may look unassuming, but the little bottle has been loaded with a blend of 10 botanicals, all designed to help carve out a moment of calm in your day. 

Not only does it smell like a five-star spa, but the highly concentrated blend of eucalyptus, fir needle, lavender, rosemary, and geranium stimulates the vagus nerve to restore inner balance. The result? Quite possibly the most soothing bath I've ever had. 

When it comes to bath products, not all are created equal. The Olverum Bath Oil differs because it has a functional fragrance, meaning it uses specific science-backed ingredients that trigger certain neurological pathways.

Not just delighting the senses, these ingredients interact with the brain pathways, particularly those within the limbic system and autonomic regulation centres.

Helping to illicit a mood change, such as preparing the mind for rest or sleep, it means this little bath oil could be a game-changer for soothing the body and the mind. 

The bath oil has been made with natural essential oils that wouldn't look out of place in a luxury spa. All 10 of the botanical ingredients have been lovingly chosen, including eucalyptus and fir needle to open airways and clear the mind, lavender and rosemary to help calm and reduce tension, whilst geranium is said to balance mood. 

Each 60ml bottle provides enough for up to 12 indulgent baths, while the 125ml bottle lasts for up to 25

Baths for me are a rare evening indulgence, so Olverum's heady bath oil is perfect for saving for those big nights in.

At £46.50 for 125ml, these little drops feel a little akin to liquid gold, but the highly concentrated formula means you only need half a capful per bath. 

The brand recommends agitating the water with your hand to disperse the oil before you get in, which, while it doesn't create mounds of bubbles, it does release the most intense, heavenly scent. 

The bath oil will sit pride of place in my bathroom, perfect for those pampering evenings in

Better still, virtually all of the oil was absorbed by my skin, leaving no greasy residue in the bath after use. The added Vitamin E left my skin feeling gorgeously soft and delicately scented, which stayed on me for hours after the bath, much like leaving a five-star hotel spa.  

While an investment, a bath oil that helps support your mind and skin with carefully selected essential oils and skin-loving ingredients, whilst simultaneously easing you into restorative slumber, feels like a worthy spend, and one that left me feeling like royalty.
