Why is my blackhead not dissolving with cleansing oil?

To organize blackheads with cleansing oil, you need to wet your hands slightly to emulsify the oil into a milky color. If you just apply the oil and massage without this process, the hardened sebum may not soften enough for effective results. Additionally, if the sebum has already hardened for a long time, home care may have limitations in organizing it, so in such cases, professional management may be helpful.
