Chelsea here, Luna’s in-house esthetician. Let’s talk about the benefits of bath bombs today and how each ingredient in them affects the skin!

Luna bath bombs have the following ingredients:
-Citric acid
-Sodium bicarbonate
-Essential oils and fragrance oils
-Food grade color and oxides
-Shea butter

These may be familiar ingredients to you, but how do they benefit the skin? Let’s start with citric acid! Citric acid is a derivative from citrus fruits and is a weak acid. Most commonly it is used as a preservative and to add a tang to food items. For Luna bath bombs, they are used for not only preservation and emulsifying, but it is great for the skin! Citric acid helps slough off dead skin cells, which in turn helps with CRF or cell renewal factor. Citric acid may help with mild acne, clogged pores, pigmentation, dark spots, wrinkles, and sun damage/tanning. Citric acid is also a source of vitamin C, which aids in collagen production!

If you like to bake then you’re familiar with sodium bicarbonate or baking soda as it’s more commonly known. Sodium bicarbonate helps to balance skin pH. It is also antiseptic and anti-inflammatory, helping to sooth redness from irritated skin. Sodium bicarbonate is also alkaline in nature, which can help soothe sunburns and subsequent blistering.

Essential oils and fragrance oils are moisturizing and can be soothing to the skin. Lavender, for example, is a great moisturizing oil and anti-inflammatory, working to help soothe irritated skin from acne, psoriasis, and eczema. Adding essential oils and fragrance oils to bath bombs help to soften the skin and provide a layer of moisture. After enjoying a Luna bath bomb, apply a layer of humectant lotion to your skin to help lock in the moisture to help improve skin health. As an esthetician, I suggest avoiding lotions with strong fragrance concentrations as these usually contain higher amounts of alcohol, which will dry out the skin and can cause irritation. Look for fragrance-free and cruelty-free lotions, there are many great over-the-counter options including Cetaphil.

As for Luna bath bomb colors, we use synthetically prepared iron oxides, which are approved for use in cosmetics in the USA, decreasing the risk of mercury, arsenic, and lead that can be found in iron oxide naturally. FD&C colors are made the same way, to ensure there are no contaminants in food from color. Many of these food grade colors are also water soluble, very important for bath bombs or the color may not rinse away and you risk staining tubs. Food grade colors are the most stable for bath bombs, providing the best shelf life as herbs can interact with oxygen and moisture, deteriorating and looking quite bad. If your bath bomb has glitter in it, it is made from mica, a naturally occurring mineral. Bath bombs with mica may leave a shimmer on the skin after bathing for an extra glow.

And last, but not least, is shea butter. Shea butter is not only moisturizing but is soothing and anti-inflammatory due to its lupeol cinnamate compound. Shea butter may also help prevent wrinkles and to help keep the skin taut as we age. It is also non-comedogenic so it will not clog pores.

Now that you know more about what goes into a Luna bath bomb, draw yourself a bath and enjoy!
