What is the most sensitive part of the body?

Lips, tongue, nipples and earlobes, the most sensitive of which is ears, will turn red as long as they are touched lightly. Some people's skin is very sensitive. As long as they are exposed to the sun, their skin will turn red and even get a rash. Sensitive skin is thin and fragile, so pay attention to sun protection. Do not eat stimulating, spicy and seafood food, do not smoke or drink. Sensitive skin should choose skin care products with mild quality and simple ingredients, preferably extracted from pure natural plants, and preferably used in small packages, so that it is not necessary to use a lot at a time.
