Description

Technical Field The present invention relates to a keratin removal sponge for a face,

The present invention relates to a sponge for removing keratinous substances present in the skin of a face, and more particularly, to a sponge for removing keratinous substances including a non-toxic raw material which is safe for the skin of the face, A sponge and a method of manufacturing the same.

In general, the keratin formed on the skin of the human hand or feet is a disease caused by excessive pressure applied to a certain part of the skin. If the treatment is not performed at the initial stage or a certain measure is not taken, .

Therefore, various methods have been used to remove keratin, for example, rubbing with a sand or sandpaper attachment, shaving with a cutter, using exfoliating drugs, or receiving medical attention when symptoms are severe And the like.

These keratin materials should be treated by a physician in case of severe illness, diabetes, or other diseases. However, in case of mild cases without pain, you can remove it by yourself.

However, the use of a cutter or a drug is not recommended because it may cause infection at the keratinous area or cause the burn due to the acid component, which is the main component of the drug.
