The moisturizing and supple feeling is completely different! It warmed me up from the inside out! I thought it would have a strong scent because it's mugwort, but it wasn't at all, which surprised me! It's colorant-free and fragrance-free, so I'm happy that I don't have to worry if my family joins in after me. lol Also, I didn't really notice it until now, but the hand bath is also very pleasant, so I recommend it! As we're approaching the time of year when it's easy to get sick with the change of seasons, I want to warm my body properly and take care of it. I'll continue to use it♪
I go to a mugwort steaming salon, and I bought this hoping to be able to combat and improve my coldness while bathing at home. When it arrived, I was surprised at how smaller it was than I expected, but the instructions said to use two capfuls, so I don't think I'll run out quickly. There's no particular scent to it while bathing, but I felt a gradual warmth within about 10 minutes, and the warmth continued even after I finished bathing. I plan to continue using it.
It's warm
I love mugwort steam baths, but in winter it's hard to get around. I want to go to a mugwort steam bath, but it's a hassle to get there. So I tried "shiyu Mugwort Bath Essence," which allows me to easily "warm up with mugwort*3." Shake well and then pour two capfuls. It's clear, has no scent, and doesn't have that fizzy feeling. There's no green smell that's typical of mugwort. (I love the smell of mugwort) It doesn't change the appearance of the bath at all. So much so that when my husband came home and asked if he could add some bath salts, he said, "Oh! There are bath salts in it!" The scent is very easy to use, even for people who don't like the feeling of the water changing. I start sweating profusely when I'm taking a leisurely half-bath. *This is purely my personal opinion. It's a bath salt I'd like to continue using during my relaxation time*3 due to the bathing effects.
As a child, bath time is my only time to relax, and I've tried so many different bath additives! I'm always soothed by the color and the scent. Shiyu was labeled "mugwort," so I wondered what the scent and color would be, but its cute appearance also made me decide to buy it! It doesn't smell like mugwort at all, nor does it have any strange medicinal scent; it's colorless and transparent! At first glance, it's hard to tell if it's working, but after a bath, I feel warm and cozy, and it lasts! Amazing! My son, who used to have trouble falling asleep, now falls asleep easily by 9 p.m.—perhaps because of the pleasant warmth. I work remotely during the day, so I often use shiyu for foot baths while working at my desk. Even when my feet get cold from the air conditioner, a shiyu foot bath is so relaxing and soothing. As the weather gets colder, I plan to enjoy a warm and cozy bath with shiyu this winter!
