Are Scented Wax Melts as Unhealthy as Scented Candles?

Are scented wax melts bad for your health like scented candles?

Scented wax melts, like candles, release fragrance oils into the air—but without a flame. This has led many to believe they’re healthier alternatives. However, whether wax melts are unhealthy depends entirely on their ingredients.

If they’re made with paraffin wax and synthetic fragrances, they can still emit volatile organic compounds (VOCs) that affect indoor air quality. That said, high-quality, clean-burning wax melts—like the ones offered by Karessa Candles—are far safer and more natural.

What’s the key difference between wax melts and scented candles?

With no wick or flame, wax melts don’t produce soot, making them ideal for those sensitive to smoke. Still, toxic ingredients can be released during warming—just like burning.

Karessa ensures both our candles and upcoming wax melts use natural soy wax and essential oils, offering clean scent without health compromises.

Are wax melts with synthetic fragrance oils dangerous?

Yes, wax melts with synthetic or chemical-based fragrances can release harmful VOCs such as:

• Formaldehyde

• Acetaldehyde

• Benzene

• Toluene

These are linked to respiratory irritation, hormone disruption, and long-term exposure risks—just like with paraffin candles.

To stay safe, choose wax melts or candles made from non-toxic, phthalate-free ingredients—like those in our Karessa collection.

Are natural wax melts safer?

Absolutely. Wax melts made from:

• 100% soy wax

• Beeswax or coconut wax

• Essential oil blends

• Phthalate-free, paraben-free ingredients

…are far less likely to cause irritation, and are more eco-friendly. They are also perfect for homes with kids, pets, or those who are sensitive to synthetic fragrances.

That’s why at Karessa, we’re working on a wax melt line that mirrors our candle standards—natural, soothing, and safe.

Tips for safely using wax melts or candles

• Always choose natural ingredients

• Use electric warmers to avoid open flame risks

• Limit use in small, unventilated rooms

• Avoid any product with strong chemical scent or artificial dyes

Karessa’s gift hampers also make it easy to share wellness-focused fragrance with others, without the worry of unhealthy ingredients.

Final Thoughts

While wax melts may seem safer due to their flameless nature, they can be just as unhealthy as candles if made with the wrong materials. The safest route? Choose natural soy-based products with essential oils—whether you’re burning a candle or melting wax.
