The Overboard star teamed up with experts at Max Benjamin to create the Calm candle, which features a blend of lavender oils with three wicks.
A portion of the proceeds from the sales will benefit the actress' charity The Hawn Foundation, which works to teach social and emotional skills to children.
Hawn says, "I created this candle to give something beautiful to people. I chose the name 'calm' because a calm environment means less stress and anxiety. Knowing that scents have powerful effects on the brain, I chose lavender for the sense of well-being it engenders.
"Together the name and the scent of this wonderful candle convey our essential message to children and parents alike: that their well-being, their sense of calm and confidence is of the utmost importance!"
