Magnesium bath salt in a glass tube with a cork lid, scented only with essential oils and enriched with sweet almond oil. At least 36 g — enough for a foot soak or a small bath. Four blends, matching Azur's soaps:
-
Sunset Dreams — lavender, eucalyptus and orange
-
Lavender Fields — lavender and rosemary
-
Wild Flower — grapefruit and rose geranium
-
Sauna Feels — eucalyptus
Contains sweet almond oil — a tree nut
Worth putting near the top. Sweet almond oil is a tree-nut derivative and this is a whole-body product. Cosmetic almond oil is refined and very low in protein, and reactions are uncommon, but if you have a diagnosed tree-nut allergy this is one to raise with your allergist rather than take on trust.
An honest word about magnesium in the bath
Magnesium bath salts are almost always sold on the promise that the magnesium "helps relax tired muscles". You will not read that here, and it seems fairer to explain why than to leave it out silently.
Magnesium is genuinely essential in the body, and it genuinely is involved in muscle function — that part is not in dispute. What is in dispute is whether magnesium salts dissolved in bathwater cross the skin in any meaningful quantity. The skin's outer layer is an extremely effective barrier to charged ions, which is precisely its job, and the studies claiming transdermal magnesium uptake are small, mostly industry-linked, and not well controlled. There is no authorised EU health claim for magnesium applied to skin.
What is unambiguously true is that a warm bath relaxes muscles. Heat increases local blood flow, reduces muscle tone and is genuinely, measurably soothing. Add a scent you like and twenty minutes of not doing anything, and the effect is real — it is simply the bath doing it, not the mineral crossing your skin.
That is a good enough reason to buy bath salts. It does not need improving on.
Essential oils in water — the safety part that matters
Essential oils do not dissolve in water. Poured neat into a bath they float as droplets on the surface and make contact with skin and mucous membranes at full strength, which is how people end up with irritation in places they did not expect.
Blending oils into a salt is a partial solution — it disperses them as the salt dissolves, which is far better than pouring oil straight in. It is still worth stirring the water thoroughly before getting in, and worth knowing that a bath with oils in it is slippery. Hold something when you get out.
