Are the ingredients of Deonatulle antiperspirant safe? Japan is a country with high body odor and body odor rate in East Asia, but you can hardly smell any strange smell when walking on the streets of Japan, because both men and women in Japan use Deonatulle antiperspirant, and its effect can be seen from its popularity alone. Aluminum salt is a commonly used antiperspirant product in the market. The principle of aluminum salt is to directly block sweat glands, which is unscientific. In addition, because the main component of this antiperspirant stone is alunite, alum, as a natural mineral salt existing in volcanic areas, is called "natural deodorant", so the composition is very safe. Alum can form a thin protective film on the skin surface, which can prevent odor, neutralize odor and tighten pores from the root.
