8 Halloween Makeup Ideas Using Products You Already Have

If you’ve ever wished your bath salts had just a little more pizzazz—maybe a bit of bubble and pop—then fizzy bath salts are going to be your new favorite thing. Think of them as a happy marriage between traditional bath salts and bath bombs. They soothe sore muscles and bring a delightful fizz when they hit the water.

Perfect for gift-giving or treating yourself after a long day, this project is easy, affordable, and a fun twist on regular bath soaks. I first whipped up a batch of these for a Mother’s Day pamper hamper, and now they’ve become a staple in my self-care stash.

Let’s dive into the fizzy magic!

What Are Fizzy Bath Salts?

Fizzy bath salts combine the benefits of Epsom salts (magnesium-rich muscle relaxation) with the bubbling fun of citric acid and baking soda—the same duo behind classic bath bombs. The result? A skin-softening soak that also fizzes, foams slightly, and releases your favorite essential oils into the steam of your bath.

Ingredients You’ll Need

• 1 cup Epsom salts

• ½ cup baking soda (sodium bicarbonate)

• ¼ cup citric acid

• 1 tbsp carrier oil (sweet almond, jojoba, or fractionated coconut oil)

• 10–15 drops essential oil (lavender, eucalyptus, rose, etc.)

• Optional: a few drops of natural liquid colorant or mica powder

• Optional: dried flower petals, herbs, or biodegradable glitter

• Glass jar or airtight container for storage

Note: Don’t use food coloring—it can stain your tub and skin.

How to Make Fizzy Bath Salts – Step by Step

Step 1: Mix the Dry Ingredients
In a large bowl, combine the Epsom salts, baking soda, and citric acid. Stir gently with a spoon or your hands to evenly distribute everything.

Step 2: Add Oils & Scent
In a separate small bowl, mix your carrier oil and essential oil(s). If using color, add it to this mixture. Drizzle it slowly over the dry mix, stirring continuously to prevent fizzing.

Step 3: Optional Add-ins
Sprinkle in flower petals (like rose or lavender), a pinch of mica for shimmer, or a dash of glitter if you’re feeling fancy. Stir gently to blend.

Step 4: Dry and Store
Spread the mixture on a tray or plate and let it air-dry for about 1–2 hours. This helps prevent clumping and pre-activation. Then transfer your salts into a glass jar or airtight container.

How to Use Fizzy Bath Salts

Scoop about ¼ to ½ cup into a warm bath as it’s filling. Watch the fizz, breathe in the aroma, and soak for 20+ minutes. Pure bliss.

Tips & Variations

• Sore Muscle Soak: Add 1 tbsp sea salt and a few drops of eucalyptus + peppermint.

• Relaxing Lavender: Lavender oil, dried buds, and a touch of purple mica.

• Romantic Rose: Rose absolute or geranium oil, dried petals, and a soft pink shimmer.

• Kid-Friendly Fun: Tangerine or vanilla essential oil, blue mica, and a sprinkle of eco-glitter (skip the herbs).

Always patch test new products. Avoid citric acid if you have broken skin or very sensitive skin. Store in a cool, dry place to keep the mix fresh and fizzy.

Perfect for Gifting

Spoon your fizzy bath salts into mason jars, tie with ribbon or jute, and add a printable tag (I can whip one up for you—just say the word). They make gorgeous handmade gifts for birthdays, teachers, spa baskets, or holiday stocking stuffers.
