It can not only reduce the swelling, but also make the internal tissues that have been suppurated out of the body as soon as possible, which is called ripening, and generally 3-4 days can achieve the desired effect. However, if the location of the infection is deeper, the effect time may be appropriately extended. After applying for a period of time, the local skin surface may break down, and it is recommended to clean well to avoid the aggravation of local infection. While applying ichthyolipid ointment, you can take some antibiotics orally as prescribed by the doctor for a comprehensive treatment, the effect will be more satisfactory.
