Summary
How To Use CBD Bath Bombs

If a long soak in the bath is your idea of heaven, you’re probably familiar with these fizzy bath time accessories. CBD bath bombs are used in the same way as a regular bath bomb so incorporating them into your bathtime ritual could not be easier. Simply fill the tub with warm water and drop it in while you’re in the bath so you can enjoy the fizzing and foaming as the product dissolves. Soak in the bath for as long as you like, but we’d recommend staying for at least 20 minutes to absorb all of the goodness.
Warm water
An ideal water temperature is around 36-37 degrees for most people. When paired with warm water, the cleansing and soothing nature of bath salts (a bath bomb staple), and the potential benefits of CBD, make a CBD bath bomb the perfect addition to your self-care routine.
Blood tends to rise to the surface of the skin when immersed in warm water. The blood vessels on the skin undergo a process named vasodilation which helps the skin regulate its temperature. When the body starts to warm up, it promotes sweating and the skin’s surface can become pink with increased blood flow. The sweat glands open up (a bath should never be hot enough to have you sweating excessively) allowing dirt and toxins to unclog from your pores. Vasodilation may also enable more nutrients to enter the skin’s tissues.
Can CBD Be Absorbed Through The Skin?
CBD applied topically won’t absorb into the bloodstream, but when applied liberally to a localised area, CBD can transfer through the dermis (skin cell layers) to cannabinoid receptors via the pores. On its own, CBD is hydrophobic, making it hard for the cannabinoid to get across the aqueous layer of the skin.
Luckily, with bath bombs, this challenge can be overcome. Since our pores are more permeable in the presence of warm water, baths can facilitate CBD entry via the pores. This is through a type of absorption called ‘percutaneous absorption’, where a product, like dissolved CBD, can enter the pores by a method known as ‘passive diffusion’.
When CBD absorbs into our skin, through our pores, it can interact with the ECS receptors on the skin’s surface. The skin has the largest amount of CB2 receptors on its surface (with some CB1 receptors there too). The CB2 receptors on the skin’s surface are responsible for moderating:
- Sebaceous glands;
- Skin temperature;
- Skincell growth, proliferation and differentiation.
This is because there are ECS receptors on many of the keratinocytes, cutaneous nerve fibres, melanocytes, dermal cells and sweat glands on the skin’s surface. Applying CBD to the skin’s surface activates the ECS receptors on the skin only.
Benefits For Skin
There are many possible benefits that come with caring for your skin with regular spa rituals. Bath bombs come blended with many skin-loving ingredients like essential oils, shea butter and himalayan salt that can go a long way in keeping the skin looking and feeling healthy.
Terpenes
Many brands will use natural terpenes to scent their product. Terpenes are aromatic compounds that are primary constituents of essential oils. In a bath bomb, which promotes relaxation and tension relief, you might find signature scents of lavender, also known as the terpene, linalool. Linalool is incredibly relaxing to the system and has been used in aromatherapeutic massages for years as a soothing, uplifting medium to calm the mind and muscles. This is just one example, there are over 100 terpenes found in cannabis all with their own benefits and unique aromas.
Can I Put CBD Oil in My Bath?
While there’s no harm in adding CBD oil in your bath, diluting CBD oil in a bath full of water is not an effective use of money or CBD.
While CBD applied topically won’t absorb into the bloodstream, a CBD bath bomb releases CBD plus other ingredients like essential oils to give you a relaxing spa experience while targeting ECS receptors in the skin.
What Are The Most Popular CBD Bath Bomb Ingredients?
From Epsom, magnesium and Himalayan salt, to the many combinations of plant oils - there’s a CBD bath bomb for every mood! Some of the most common ingredients you’ll find in quality CBD bath bombs are:
- Salt (Epsom, magnesium, Himalayan);
- Baking soda;
- Coconut oil or shea butter;
- CBD extract;
- Essential oils (e.g. lavender, orange, eucalyptus, rosemary);
As is often the case, natural ingredients are best. Aromatic essential oils naturally scent your bath and often have skin-benefiting properties. Some bath bombs are citrusy for a refreshing experience, while others have heady aromas of rose and sandalwood - it’s simply down to your personal preference. Because the ingredients used to create bath bombs are easy to source, it's even possible to create your own.
When buying bath bombs, check the ingredients list for artificial ingredients and chemicals. Bath bombs should only contain ingredients that are kind to the skin and that won’t upset the natural PH of the body.

How To Choose CBD Bath Bombs
Just like other CBD products, it’s important to choose CBD bath bombs from reputable brands - but how do you sort the wheat from the chaff? To choose the very best CBD products, check for the following:
- Legal levels of THC.
- Made from naturally-grown hemp (hemp grown without pesticides and fertilisers is safer and less toxic).
- A Certificate of Analysis (COA). Your CBD product should have been tested by a lab, preferably third-party, to be sure that the CBD content marries up with what’s on the label.
- Made with natural ingredients.
- Backed with positive and verified reviews.
How To Shop For CBD Bath Bombs
As well as the above, it’s also important to buy from a company that’s upfront about where it sources its hemp and how it makes its products. The more information a company can provide, the better. One factor that makes CBD bath bombs different to your regular bath bomb is CBD strength. If you’re new to CBD, you might want to start with one in the low-to-mid range (between 25 and 50mgs per bath bomb). If you’re looking for a stronger effect, some bath bombs come in even higher strengths but expect to pay more.

How Often Should You Use CBD Bath Bombs

There’s no hard and fast rule regarding how often you should use CBD bath bombs. We’d say use a bath bomb whenever you feel the call for some quality me-time. As a general rule, twice a week usage of these bath bombs would work well.
Does CBD Soap Get You High?
No, not only do legal CBD bath bombs not contain enough THC to get you high, but topical CBD products, with the exception of CBD patches, don’t pass into the bloodstream so you don’t need to worry about any possible psychoactive effects.
Can CBD Bath Bombs Be Harmful?
CBD bath bombs made with natural, well-researched ingredients should not cause any harm, however, always check the label if you have any intolerances or sensitivities to certain ingredients. Avoid products that contain artificial and potentially harmful elements like acetone, phthalates, ethanol, and ethyl acetate. Bath bombs, especially CBD bath bombs, are all about wellness so avoid artificial fragrances, dyes, additives and preservatives as they can cause redness, itchiness and scaling skin.
Safety and Side Effects
CBD is generally considered to be safe, as reported by the World Health Organisation, however, some people may experience minor side effects. Potential side effects like drowsiness, appetite changes and GI upset are associated with ingesting CBD. When applied topically, it is more often other ingredients that can cause irritation and side effects. It’s important to exercise caution with any new-to-you topical product. Even natural ingredients like essential oils may irritate sensitive skin. To avoid upsetting the PH of the vagina, it’s best to use products that are fragrance-free and hypoallergenic.

So, find the right CBD bath bomb for you and get relaxing!
FAQ
How Do I Use a CBD Bath Bomb?
It’s as simple as any bath bomb - either crumble the bath bomb under the tap, as the water fills your tub, or add the bath bomb to your already full tub of water and then run your hand through, so all dissolves!
Can Full Spectrum CBD Bath Bombs Get Me High?
No - full-spectrum CBD bath bombs, even with trace amounts of THC, can’t get you high. The cannabinoids never enter your bloodstream, when they’re soaked in, topically. But, even if you were still scared of any unlikely chance of getting high by your bath bomb, don’t worry. Studies actually show that CBD can negate the intoxicating effects of THC. So lie back and relax!
Are CBD Bath Bombs Okay For Sensitive Skin?
Always check the label if you have sensitivities to certain ingredients like essential oils. However, most natural bath bombs will be suitable for sensitive skin. Always dilute the bath bomb in enough water so it fully dissolves if you are sensitive to baking soda and Epsom salts. The manufacturer may advise against use if you have particularly sensitive, broken or irritated skin. Always read the label.
How Long Should I Soak In a CBD Bath?
We recommend soaking in your CBD bath for ten to twenty minutes (although, if it suits you, you can sit in your bath for longer!)
Do CBD Bath Bombs Expire?
Although we recommend using your newly purchased CBD bath bomb as soon as possible, if you want to save yours, we suggest you look at the estimated expiration date (which usually comes with the packaging). To give you a rough idea of how long you should store your bath bomb, many CBD-infused ones tend to expire after six months of purchase.
Are CBD Bath Bombs Good For The Environment?
Most CBD bath bombs are, yes! In all their dissolvable, natural states, are fine for the environment. Just avoid bath bombs with glitter in them as most glitter is non-biodegradable.
Are Bath Bombs Vegan?
Just like any other selfcare products, CBD bath bombs can be formulated with many different ingredients so always check the label. While most CBD bath bombs will be vegan, some companies may use non-vegan ingredients like honey, beeswax or milk.
What To Pay Attention To When Using Bath Bombs?
While many bath bombs look good enough to eat, they’re for external use only. Avoid contact with your mouth and eyes and keep out of reach of children.
What Are CBD Bath Bombs Made Of?
What makes CBD bath bombs different to other bath bombs is of course the ingredient, CBD! Depending on the brand, bath bombs are usually made with salts (like Epsom or magnesium), citric acid, essential oils and a variety of other ingredients depending on what the bath bomb is targeting (e.g. relaxation, muscles, moisturising).
What Makes CBD Bath Bombs Fizz and Dissolve?
Baking soda and citric acid are the ingredients most often used to make bath bombs fizz and melt when dropped in water.
How Long Can I Keep a Bath Bomb Before Using It?
Other than CBD, there are other ingredients used to make the bath bombs. These include baking soda and citric acid, which make the bath bombs fizzle when they get in to contact with the water.
How Safe Are Ingredients Used In Making CBD Bath Bombs?
We choose reputable brands that make high-quality CBD bath bombs with the best ingredients. When dissolved in the bath and assuming there are no allergies or sensitivities, the ingredients are safe for your skin and will not damage your bathtub or drainage system.
Are CBD Bath Bombs Safe During Pregnancy?
We do not recommend CBD bath bombs to pregnant women as there hasn't been enough research on this population.
Can I Use CBD Bath Bombs On My Kids?
Always check the manufacturer's instructions, however, most bath bombs can be used for children that are two years and over. However, always supervise bath bomb use and ensure it’s not placed in the eyes or mouth. It’s important to note that children’s skin is more sensitive, so avoid them if you're unsure about any of the ingredients.
Can CBD Bath Bombs Dry The Skin Out?
Quite the opposite - many CBD bath bombs are moisturising for the skin. Look for ingredients like shea butter and coconut oil if you’re after a moisturising experience.
Will CBD Bath Bombs Irritate My Skin?
Avoid using topical products on broken skin unless it’s specified it’s okay. It’s important to know if you have any sensitivities or allergies to specific ingredients before using a product. Despite this, products that use natural ingredients will usually be perfectly safe and beneficial for the skin.
Will Bath Bombs Stain My Tub?
If you’re worried about staining the bathtub, choose neutral coloured bath bombs and bath bombs formulated with natural ingredients. Some more vibrantly coloured bath bombs may leave a ring of colour, but this can be easily wiped off once the bath has drained.
Are CBD Bath Bombs Legal?
Yes! Bath bombs with CBD are perfectly legal as long as they meet certain requirements like the source (low-THC hemp) and the amount of THC (no more than 1mg). We make sure all of our CBD products meet legal requirements so you can shop with ease.
How Much CBD Is In a Bath Bomb?
This entirely depends on the brand and the product but most CBD bath bombs will contain 25mg-50mg per bomb. This variety gives consumers the freedom and flexibility to choose the right CBD concentration that works best for them.
