The research on the ingredients
The Slumber Bar is a cosmetic — a light, moisturizing cleanse wrapped in a cedar-forest scent. But the aromas and oils it's built from have been studied in their own right: lavender in human relaxation research, forest environments in studies of calm, and plant oils in skin-barrier science.
2013: A peer-reviewed review reported calming effects of lavender aroma on the nervous system, linking it with improved relaxation.
Koulivand, Khaleghi Ghadiri & Gorji, Evidence-Based Complementary and Alternative Medicine, 2013 — review of human and experimental studies on lavender and the nervous system.
2010: In controlled field studies, time in forest environments was associated with lower cortisol, lower blood pressure, and calmer nervous-system activity than city settings.
Park et al., Environmental Health and Preventive Medicine, 2010 — the foundational "shinrin-yoku" (forest bathing) research across 24 forests in Japan. The Slumber Bar's fir-and-cedar aroma is crafted to evoke exactly that setting.
2018: A peer-reviewed review described how topical plant oils — including olive, coconut, and shea — support the skin's natural barrier.

Step out of the day, gently
The Slumber Bar is built around a simple idea: the scent of a cedar forest tells your body the day is over. Fir needle and lavender fill the warm steam of an evening shower — the same aromas present in the forest settings researchers have studied for their association with lower stress and calmer nervous-system activity.
Meanwhile the saponified oils do quiet work of their own, cleansing through plant fats rather than harsh detergents so your skin's natural moisture barrier stays intact. Expect a soft, comfortable finish, a light foresty scent, and a shower that starts to feel like the beginning of rest.
- A fir-and-lavender aroma that signals evening calm
- Light, moisturizing cleanse that never strips your skin
- A simple nightly ritual to close the day
