What is a Bath Bomb? What They Do & How To Use

Mar 13, 2025

Do you remember taking bubble baths as a kid? They were the ultimate treat. Warm water, endless bubbles, maybe even a rubber duck if we’re feeling nostalgic. Fast forward to today, and this thing called a “Bath Bomb” has seemingly stole the show.

This is no surprise to me.

Think of a bath bomb as the next-level to the bubble baths you loved as a kid. The moment a bath bomb hits the water, your ordinary soak turns into a spa day at home.

But bath bombs aren’t just a neat little Tik-Tok viral sensation. They look great on your Instagram story, but they don’t get the credit they deserve when it comes to clean beauty.

So, let’s change that. I’m here to break it all down when it comes to bath bombs, your skin, and your overall health.

Let’s dive in!

 

What Is a Bath Bomb?

A bath bomb is a compacted mixture of dry and wet ingredients that fizzes when dropped into water. As it dissolves, it releases a blend of essential oils, colors, and skin-loving ingredients to enhance your bath.


A Brief History

 

Bath bombs as we know them today were invented in 1989 by Mo Constantine, the co-founder of Lush Cosmetics. Inspired by the fizzing reaction of Alka-Seltzer tablets, she created the first bath bomb to elevate bath time with a multisensory experience. Since then, bath bombs have evolved into a skincare and wellness staple, with a variety of formulations designed for relaxation, hydration, and even aromatherapy.

 

What Makes Bath Bombs Fizz?

 

 

The signature fizz of a bath bomb comes from a simple but effective chemical reaction between two key ingredients: baking soda (sodium bicarbonate) and citric acid. When these dry ingredients come into contact with water, they react to create carbon dioxide bubbles, producing the delightful effervescence that bath bombs are known for.

Different Types of Bath Bombs

Not all bath bombs are created equal. Here are a few popular varieties:

  • Single-layer bath bombs – These are simple, classic bath bombs that dissolve evenly in water, adding fragrance and color to your bath.

  • Multi-layered bath bombs – Designed for a longer-lasting experience, these bath bombs dissolve in stages, revealing different colors and scents as they break apart.

  • Surprise-filled bath bombs – Some bath bombs contain hidden surprises, like dried flowers, skin-conditioning butters, or even small trinkets for a fun bath-time experience.


Are Bath Bombs Good for Your Skin?


Yes, bath bombs can be a powerful addition to your skincare routine. They vary in ingredients, offering different advantages on the skin, including:  

  1. Moisturization– Bath bombs can hydrate and soften skin when they contain ingredients like shea butter, coconut oil, or goat milk. These nourishing elements help combat dryness and leave skin feeling smooth.

  2. Skin pH Balance – Most bath bombs have a slightly acidic to neutral pH, which is generally safe for skin. However, those with harsh detergents or artificial additives can strip the skin’s natural moisture barrier.

  3. Epsom Salt– Bath bombs containing Epsom salt can help relax muscles and reduce inflammation. This makes them a great option for post-workout recovery or stress relief.

Are they overhyped? 

Some bath bombs are purely for aesthetics, offering only color and scent. However, high-quality bath bombs with natural oils and minerals provide genuine skin benefits.

 

How to Use a Bath Bomb Properly

 

Using a bath bomb is easy, but just in case you’re unsure, follow these steps.

  1. Prepare Your Bath – Fill your tub with warm water. Hotter water speeds up the fizzing process, but make sure it’s a comfortable temperature.

  2. Drop It In – Place the bath bomb in the water and watch it dissolve, releasing its colors, scents, and skin-nourishing ingredients.

  3. Stir for an Even Blend – Swirl the water with your hands to mix the oils and fragrances evenly for a more immersive experience.

  4. Soak and Relax – Stay in the bath for 15-30 minutes to allow your skin to absorb the moisturizing and therapeutic ingredients.

Pro Tip: If you don’t have time for a full bath, drop a bath bomb into a basin of warm water for a relaxing foot soak. This is especially beneficial for tired, achy feet or post-workout recovery.


How to Choose the Best Bath Bomb

 

Not all bath bombs are created equal. Now that I think about it, not all skincare products are created equal. All a brand has to do is slap on “natural” or “organic” and quiet honestly, those words have little meaning nowadays. What does have meaning is the ingredients on a product label. 

To make sure you avoid irritation and have a spa-level experience, look for high-quality, skin-friendly ingredients.

Ingredients

  • Goat Milk – Provides deep hydration and gentle exfoliation.

  • Essential Oils – Offer natural fragrance and aromatherapy benefits.

  • Epsom Salt – Soothes sore muscles and promotes relaxation.

  • Natural Colorants – Mica, beetroot powder, or clay prevent staining.


What To Avoid

 

  • Synthetic Dyes – Can stain skin and bathtubs.

  • Sodium Lauryl Sulfate (SLS) – A harsh foaming agent that may cause dryness.

  • Glitter/Microplastics – Hard to clean and harmful to the environment.


Do Bath Bombs Expire?

 

Yes, bath bombs do expire, typically losing their fizzing power after six months. Over time, exposure to air and moisture can weaken their effectiveness, making them less bubbly and fragrant.

 

Storage Tips for Longer Freshness

  • Keep them dry – Store in an airtight container to prevent moisture from activating the fizz prematurely.

  • Avoid heat and sunlight – Keep bath bombs in a cool, dark place to preserve essential oils and fragrances.

  • Use fresh ones first – If you have multiple bath bombs, use the older ones first to enjoy the full experience.


Bath Bombs for Different Needs

 

Different ingredients offer unique benefits, making some bath bombs better suited for specific skincare or relaxation needs. Here are the best bath bombs by Ingredient:

Why Goat Milk is a Top Choice in Bath Bombs


Goat milk is an almost magical ingredient in bath bombs, offering hydration, exfoliation, and skin-soothing benefits. It makes a real difference for your skin through:

  • Deep hydration – Packed with vitamins and fatty acids, goat milk deeply moisturizes, helping to restore dry, cracked skin.

  • Gentle exfoliation – Contains lactic acid, a natural exfoliant that removes dead skin cells for a smoother, softer feel.

  • Perfect for sensitive skin – Free from harsh chemicals, it’s ideal for eczema, psoriasis, and dry skin, providing relief without irritation.
