10 Best Bath Salts and How to Use Them Correctly
The 2024 Met Gala was last night, and amidst the surprise of Sydney Sweeney’s black bob and Maria Sharapova’s gown made of Boll & Branch bed sheets, we also got the news that Jessica Biel bathed in a whopping 20 pounds of bath salts ahead of the event. Yes, you read that right—20 pounds of Epsom salts. In a TikTok Biel posted on the evening of May 5 (the day before the Met Gala), the actress can be seen dumping five four-pound bags of Dr. Teal's Epsom Salts ($5) into her tub before her bath. She adds that she makes the water “as hot as you can take it” and soaks in her salty concoction for 30 minutes.

What are bath salts
“Bath salts are typically made from magnesium sulfate, also known as Epsom salt, or Dead Sea salt,” says Marisa Garshick, MD, FAAD, a board-certified dermatologist at MDCS Dermatology and assistant clinical professor at the NewYork Presbyterian Weill Cornell Medical Center. “They dissolve in water bath water and are thought to have many benefits including stress relief [and] reducing joint pain, muscle stiffness, anxiety, and headaches, as well as skin conditions like dry skin and eczema.”
While more evidence is needed to support these claims, there’s no denying the pleasure that a dip in the tub can offer you; according to one small study1, drawing a warm bath can lessen stress and uplift the mood. And if bath salts can compound the joy you experience, then why not add them to the mix?
What to look for
When shopping for bath salts, you’ll usually have the option between ones made with Epsom salt or sea salt, both of which come with their own unique benefits. As mentioned, Epsom salt is made up of magnesium sulfate, which acts as an anti-inflammatory ingredient. “Magnesium helps reduce inflammation caused by E-selectin, which is a molecule that causes inflammation in the endothelial layer of the skin,” says New York-based board-certified dermatologist Dendy Engelman, MD. She adds that, in reducing inflammation, magnesium can also improve overall skin health.
Sea salts, on the other hand, are rich in minerals that you wouldn’t typically find in Epsom salt. “Sea salts contain magnesium as well as many other mineral salts like potassium, calcium chloride, sodium, and bromide,” says Francesca Fusco, MD, a board-certified dermatologist at Wexler Dermatology in New York. “For patients with inflammatory skin disorders like eczema, a soak in Dead Sea salts2 may reduce inflammation and enhance hydration,” she says, referencing a 2005 clinical trial3 published in the International Journal of Dermatology. Whatever your preference, you’ll want to ensure these ingredients—whether Epsom salt or Dead Sea salt—are listed at the top of a product list, says Dr. Garshick.
Many bath salts are also scented using synthetic fragrances, natural fragrances (like essential oils), or a combination of the two, but you may want to steer clear of additives if you have sensitive skin. “These can be irritating and pose a potential risk for an allergic reaction or contact dermatitis,” says Dr. Garshick. Otherwise, the right scent can work to elevate the experience. Lavender, for example, is a popular scent that can help you drift off to sleep, while energizing scents like ginger and eucalyptus can provide a jolt of energy.
How to *correctly* use bath salts
They’re pretty easy to use! Once you have your salts, simply pour in the recommended amount into warm bathwater. Dr. Garshick also recommends soaking for up to 15 minutes unless otherwise directed and using bath salts up to three times per week.
The 10 best bath salts for full-body bliss
Key ingredients: Epsom salt, lavender oil
This Epsom salt soak from Dr. Teal’s has Dr. Garshick’s stamp of approval for relieving stress and muscle pain—and I love it, too. Its lavender scent wafts from the bag, and it lingers when the salt is poured into warm bathwater. Be it from the Epsom salt, the soothing scent of lavender, or both, I leave my bathtub in a state of bliss, which makes drifting off to sleep much easier. One bag will last you a long time, and you can shop it in two sizes. The 3-pound option costs less than $6, making it budget-friendly and accessible for bathing enthusiasts of all budgets.

Pros:
- Scented with soothing lavender

For a little under $5, you’ll receive a 4-pound bag, making it the most budget-friendly pick on the list.

There are three scents to choose from, each with a distinct vibe to elevate your bath experience. The first is No. 1, a warm blend of amber, clove, and tonka bean. Then there’s No. 2, which combines pink pepper with California lemon and cedarwood. The last option is No. 3, a fresh fragrance with a woody base of sandalwood and Haitian vetiver.
Scent: No. 1 (amber, cedar leaf, clove, lemongrass, medjool date, tonka bean), No. 2 (pink pepper, gurjun balsam, California lemon, Virginia cedarwood) and No. 3 (eucalyptus, sandalwood, cassis, Haitian vetiver)

You can select from two options—the Muscle Soak, which contains peppermint that provides a cooling sensation to alleviate muscle aches, or the Sleep Soak, which is infused with lavender to offer you some peace of mind. Even though it skips out on synthetic fragrances, it’s formulated with fragrant oils, so keep that in mind if you’re sensitive to essential oils. While there is only one size available, the 24-ounce bag should last you up to three baths.

Size: 24 oz.
Pros:
- Contains Epsom and Dead Sea salts
- Infused with 300 mg of sustainably sourced CBD
- Vegan and cruelty-free

Key ingredients: Sodium chloride, magnesium sulfate, colloidal oatmeal
If your muscles are as tight as a fist, you might want to try Tenoverten’s bath soak, which is recommended (and used) by Isabella Boylston, a professional ballet dancer based in New York. “The bath ritual is honestly as much about relaxing my mind as it is about my physical body,” Boylston previously told Well+Good, and the bath soak delivers on several fronts.
It’s made with Epsom salt and arnica extract—two ingredients that help Bolyston relieve muscle aches—and a bevy of skin-soothing ingredients, like colloidal oatmeal, jojoba oil, and aloe. There is also the scent (a blend of eucalyptus and peppermint essential oils), which is meant to be reminiscent of “a spa day,” said Bolyston. In addition to being vegan and cruelty-free, the formula is also eight-free, so it’s formulated without harsh chemicals like formaldehyde and xylene.
Scent: Eucalyptus and peppermint
Size: 16 oz.
Pros:
- Aids in muscle recovery and relaxation
- Helps to moisture skin
- Eight-free formula
- Vegan and cruelty-free
Cons:

Key ingredients: Epsom salt, CBD, meadowfoam seed oil
Prima packages Epsom salt as fizzy bath bombs. Besides Epsom salt, the bomb releases moisturizing meadowfoam seed oil and 25 milligrams of broad-spectrum CBD oil into your bathwater to eliminate the need for body lotion after your soak. Couple that with its eucalyptus and lavender scent, and you’re promised to emerge from the tub in a more relaxed state of mind. One bath bomb will set you back $15, but for a few more dollars, you can purchase it as a set of four. Plus, you can rest easy knowing that the product is made vegan and cruelty-free.
Scent: Eucalyptus and lavender
Size: 6 oz./ bath bomb
Pros:
- Helps to moisturize skin
- Infused with 25 mg of broad-spectrum CBD
- Vegan and cruelty-free

Key ingredients: Dead Sea salt
If you want the most bang for your buck, consider this option from Yareli. It packs Dead Sea salt flakes imported straight from Israel in a 15-pound bag, and it’ll only set you back just a little over $33. What’s more, the product is EWG-verified, vegan, cruelty-free, and made with no unnecessary ingredients. It’s also available in 3- and 5-pound bags, and in six options, including an unscented version, which is ideal for those who are sensitive to fragrance. If anything, it might leave behind some residue after your bath—a tradeoff for those who want something that is as easy to clean as it is to use.
Scent: Unscented, almond, eucalyptus, lavender, rosemary mint, tea tree
Size: 3, 5, and 15 lbs.
Pros:
- Largest option on the list

Key ingredients: French gray sea salt, French green clay
If you want to make your bath as luxurious as possible, opt for bath salts made from Pursoma, a brand that prioritizes making products using quality ingredients. We love the Digital Detox, which contains organic gray sea salt and green clay both harvested in France, and leaves out fragrance, parabens, and sulfates. The ingredients work together to soothe skin and whisk away dead skin cells. One tradeoff: it’s expensive—a bag of the stuff (which only has enough product for one bath) will set you back $28, but this is the price to pay for its quality.
Scent: Fragrance-free
Size: 10 oz.
Pros:
- Ideal for people who are sensitive to fragrance
- Helps to exfoliate skin
- Free of parabens and sulfates
- Available in several variations
Cons:
- Priciest option on the list
- Single-use size
Key ingredients: Himalayan and Dead Sea salts, palo santo, lavender, and vetiver essential oils, butterfly pea flowers
What sets the Sounds Mystic Bath Salts from the others on the list is its versatility. Use it as you would a bath salt, or mix it with honey and massage it into your skin as a body scrub. It’s made with a combination of Himalayan and Dead Sea salts and is scented with a woodsy-floral blend of palo santo, lavender, and vetiver. To add to the experience, the product contains butterfly pea flower, which will tint your bathwater an otherworldly sapphire blue (don’t worry, it won’t stain the tub). If anything, we wish it came larger, but the manufacturer indicates that one packet will last up to five baths. Also, be sure to store as instructed—the product contains no additives or preservatives, and when exposed to light or oxygen, it’ll affect its quality and color.
Scent: Palo santo, lavender, and vetiver
Size: 6.7 oz.
Pros:
- Both a bath soak and body scrub
- Contains Himalayan and Dead sea salts
- Free of additives and preservatives
- Available in several variations
Cons:
- Smallest option on the list
