Bath salts are a product derived from sea salt or rock salt. While they have only become popular in the Western world in recent years, their invention isn't recent at all. Bath salts have been used in different cultures for thousands of years, both for their health benefits and their aesthetic properties.

Many believe that bath and regular salts are similar, but this isn't true: their mineral contents are different. Unlike table salt, the salts used to make this product are rich in magnesium, sodium, calcium or potassium. They can improve your skin's overall health, strengthen its protective barrier and alleviate certain skin conditions.


  • Bath salts can come from different sources and offer various effects depending on their chemical composition and the aromas added to them.
  • Not all are composed of natural ingredients. Some are enriched with synthetic perfumes, silicones, and other petroleum derivatives.
  • It is important that you take your skin type and the results you want into account before buying bath salts. Every product is different.

Shopping Guide: Everything you should know about bath salts

Bath salts are a very common product in most bathrooms, and yet they remain quite mysterious for the public. As we mentioned earlier, many people still believe that table salt and bath salts are the same product. In the following section, we've answered some key questions regarding bath salts to help you better understand them.

What are bath salts and what are they used for?

Bath salts are soluble inorganic substances that are combined with hot water — generally in the bath — to reap the benefits of their health properties and to relax. They are often mixed with other components, such as essential oils, for example. This helps enhance their effects or add their properties to those of the salts themselves.

Although their name derives from their resemblance to common salt, they have a different chemical composition. They can be classified into two groups, depending on their origin: sea and rock salts.

Sea salt is created by the sun evaporating seawater, while rock salt is found in underground deposits.

Why should I use bath salts?

Quality bath salts contain several of the elements that your body needs, such as magnesium, iron, sodium or calcium. Combined with hot water and essential oils, mineral-rich salts help relieve muscle and joint pain linked to overexertion or even arthritis.

Sodium is combined with water to maintain the hydration of the outer layer of the skin and can be used to treat various skin conditions, such as eczema or psoriasis. The aromatic properties of most bath salts also contribute to mental relaxation and can be very useful for people suffering from insomnia.

Type of bath salts Properties
Relaxing The combination of minerals, hot water and essential oils present in many bath salts provides a sense of relaxation and relieves stress.
Magnesium Magnesium found in bath salts has moisturizing properties.
Good for blood flow Hot water opens pores and promotes the penetration of minerals such as zinc, potassium and calcium into your skin.
Detoxifying Pores open and the bath salts' minerals cleanse your skin of toxins.
Pain relief Some products can even relieve arthritis-related pain.
Antimicrobial The presence of sodium and other minerals in these products acts as a natural preservative on your skin.

How should I prepare a bath with my salts?

Getting ready to have a full-on bath with your salts or simply to dip your feet in is very straightforward. First of all, you'll have to put the plug of the bathtub in. You can then pour in your bath salts. Our advice is to put them under the water jets so that they dissolve better and release their aroma if they're perfumed salts.

How much you should use will mostly depend on your tastes and the type of bath you want to have, but around 100 grams is a good middle ground. The water temperature should be the hottest that you can comfortably handle. Once the tub is full, turn off the water, dive in and enjoy.

Do bath salts have other uses?

They can actually be used in many different ways. If you believe that bath salts are only good to be put in the bath, you might think that this product isn't all so useful after all. However, you should know that they have many different uses, all of which are beneficial both to your health and to your appearance.

  • You can use them as a face mask if you mix them with a little water to create a paste.
  • They can be used as a body scrub when mixed in equal proportion with water or with a carrier oil, such as olive oil, almond oil or coconut oil.
  • If you dissolve bath salts in hot water and then let the blend cool down, you'll have a natural, antibacterial facial lotion, ideal for acne-prone skins.
  • You can even use them to improve your oral hygiene if you mix them with baking soda. This formula has a whitening and disinfectant effect on the teeth.
  • They are also used to treat nails and cuticles. All you have to do is dissolve them in a bowl of hot water and dip your hands in for a few minutes.

What types of bath salts are there?

In addition to sea salts and rock salts, there are three subcategories of bath salts: the Epsom salts, which come from the UK region with the same name; the Dead Sea salts, which indeed come from the Dead Sea; and the Himalayan salts, which are extracted from areas close to the Himalayan mountain range. Even more types exist, but these are the most frequently used.

Type of bath salts Properties
Epsom salts They are colorless, rich in magnesium, and can relieve muscle and joint pain. They remove toxins from the body and exfoliate the skin.
Dead Sea salts Dead Sea salts are colorless, rich in potassium and calcium, prevent fluid retention and improve blood flow. They help osteoarthritis and psoriatic arthritis.
Himalayan salts They are pink due to their high iron content. They improve blood flow and reduce muscle inflammation.

What type of bath salts should I use?

As you can see, each type of bath salts offers different properties — although some are commonly shared. This is why you must choose a specific type depending on your needs and goals. In any case, we strongly encourage you to always opt for products that are as natural as possible and without synthetic ingredients such as perfumes.

People looking to relieve muscle and joint pain should opt for Epsom salts. Dead Sea salts, on the other hand, are particularly useful for skin conditions and to improve the texture of the skin, even if it is healthy. Finally, Himalayan salts are what you need for a relaxing bath before heading off to bed.

What are the effects of the different aromas?

While not all bath salts are scented, they generally are and therefore often used in aromatherapy. Each aroma has a specific impact on your mood, which is why you should choose your bath salts depending on the sensations you want to experience. We recommend that you buy salts whose aromas are extracted from natural ingredients.

Aroma Uses
Lavender or mint The smell of lavender or mint are recommended to relieve stress or to help fall asleep.
Citrus Citrus fruits have the ability to give you energy, which is why they are most recommended for a morning dip.
Eucalyptus Eucalyptus works particularly well for relieving congestion, so it's ideal when you have a cold or suffer from allergies.
Lemongrass Lemongrass bath salts are useful if you have headaches or jet lag.

How can I use bath salts if I don't have a bathtub at home?

It is increasingly common not to have a bathtub at home. We live in an extremely fast-paced world, we have time for nothing and it is true that taking a shower is much faster than taking a bath. But don't you worry: you don't need a bathtub to reap all the benefits of bath salts.

If you mix them with carrier oils to create a thick paste, you can use them in the shower as a body scrub. The steam from the hot water will help dissolve the salts and you'll be able to enjoy their properties and their aromatic vapors. You can naturally soak your hands and feet in bath salts to relax them after a long day.

Are there contraindications to using bath salts?

The bath salts themselves present no contraindications. However, too frequent or too long immersion baths can be harmful, especially if you have sensitive skin or if you have blood flow problems. This is because it can dehydrate your skin or give you this heavy feeling in the joints.

You shouldn't bathe in very hot water ― with or without bath salts ― more than once a week, and you have to save water, too! You are not advised to spend more than half an hour immersed in the bathtub. When you get out of the bath, make sure to apply your usual moisturizing cream or oil to reduce the risk of dry skin.

Shopping Criteria

Dipping in bath salts is a very relaxing experience that can relieve muscle aches and leave you with a revitalized feeling on the skin. As you know, many different products are available out there and picking the right one can be quite a challenge. In the section below, we'll look at five key factors to help you make the best purchase:


This is naturally the most important factor you should consider when shopping for your very own bath salts. We recommend that you opt for products with all-natural ingredients, since they are less dangerous to your skin and are less likely to trigger or worsen allergies. They also tend to be more effective.

As we mentioned earlier, we advise you to go for bath salts with essential oils if you're looking for a scented product. That being said, if you fall for scentless bath salts, keep in mind that you can add the aroma yourself by mixing in a few drops of your favorite essential oils.


You now know that the different aromas featured in bath salts all offer varying properties and health benefits. Nowadays, you can choose from a very broad selection of scents: herbal, floral or fruity are the most popular. While you can let yourself get carried away by a pleasant smell, know that you'll also enjoy all its effects, too.

If you like to change things up from time to time, your best option will be to purchase scentless bath salts. You can then combine them with different essential oils. Remember to check their properties and mix them up to enhance their mental, healing and medicinal properties.

Avoid synthetic perfumes, as they can favor the appearance of skin allergies.


Bath salts can come in a wide variety of colors. On the one hand, the color may be influenced by the chemical composition ― as we said earlier, Himalayan salts have a pink color due to their high iron content. On the other hand, however, colors may be added using natural or synthetic dyes.

The colored salts dye your bath water and can increase their effects, while being aesthetic at the same time. We encourage you to opt for salts that have been colored with natural ingredients, such as herbs and flowers.

You can add a few drops of food coloring in your whitish salts to give them the hue you want.

Crystal size

While we generally think that the texture and size of bath salts are coarse and large, this actually isn't always the case. Nowadays, you can find bath salts on the market with small, medium, large or very large crystals. You'll want to favor specific sizes depending on how you want to use them.

If you want to use your bath salts as a body scrub by mixing them with essential oils, for instance, you should go for small crystals. Larger ones will be ideal for your immersion baths. Finally, you may want to opt for medium-sized crystals to dip your feet and hands in a vat, as they will dissolve better.


We discussed earlier the most common origins of bath salts: Epsom, the Dead Sea, and the Himalayas. As you know, each one has a different composition, a varying purity index, and therefore different properties. Himalayan salts, for example, are rock salts formed at very high pressure and are considered to be the purest.

One thing you'll have to pay particular attention to when shopping for bath salts is that they're actually from where they claim to be. Manufacturers can sometimes manipulate their labels to make you believe that you're purchasing Epsom salts, for instance, when it is actually common salt with properties similar to those of Epsom salts. You should always carefully read the label.


Humans have long known about the health properties of bath salts. This product is now found in many bathrooms around the world, and it is important that you know that every salt is different. Their properties vary depending on their origin, their chemical composition or the essential oils that are added to the formulas.

We hope that our shopping guide helped you better understand the vast world of bath salts. As you now know, the benefits you could reap from buying a bottle of bath salts are aplenty, and you should be clear about what type of salts you want and what effects you're looking to achieve.
