HOT TAB is essential for the "Bicarbonate Warm Bath Method," which involves soaking in mildly warm water for 15 minutes. It has gained widespread support since its release.
We hope that during your relaxing bath time, both your mind and body will feel refreshed, allowing you to go to bed with a warm body. Let's create a healthy body and enhance beauty with daily baths!
For all products, dissolve the tablets in lukewarm water (96.8°F - 105.8°F), using three tablets for 160 liters (four tablets for 200 liters) of water. In summer, enjoy a relaxing soak at around 96.8°F, and in winter,
we recommend soaking at up to 105.8°F for 15 to 30 minutes or longer using the bicarbonate warm bath method.
