It has no scent and is colorless and transparent.
Somehow the bath water feels thick and moisturizing.
A luxurious 15-minute bath in a "beauty serum" [Product Name] BARTH Neutral Bicarbonate Bath Additive BEAUTY [Usage/Texture] When dissolved in hot water, it creates fine bubbles, giving the water a smooth, viscous texture. It's fragrance-free and color-free, allowing you to fully appreciate the quality of the ingredients. [Favorite Points/Benefits] Not only does the bath's bicarbonate ions warm you from the inside out, but its greatest feature is its inclusion of collagen and hyaluronic acid. After your bath, your skin will feel moisturized and smooth, just like after applying serum, retaining moisture even in dry seasons. [Recommended Use] Add three tablets to lukewarm water (37-40°C) and soak for at least 15 minutes. We recommend rubbing the water into your face and hair for total body care.
I still didn't understand the effect.
I don't like soaking in the bathtub for 15 minutes, so I hope it will be effective in a shorter time. After the bath, I feel very warm and my skin feels moisturized. Since it is fragrance-free and color-free, I hope it will come out with a relaxing scent!
