3. Mphamvu yoletsa matenda

pH ya nembanemba ya sebum ili pakati pa 4.5 ndi 6.5, yomwe ndi asidi wochepa. Asidi wofooka uwu umathandiza kuti ulepheretse kukula kwa tizilombo toyambitsa matenda monga mabakiteriya ndipo umadziyeretsa wekha pakhungu, motero ndi chitetezo cha mthupi pamwamba pa khungu.

Kutulutsa kwa tinthu ta sebaceous kumayendetsedwa ndi mahomoni osiyanasiyana (monga androgens, progesterone, estrogen, adrenal cortex hormones, pituitary hormones, etc.), omwe androgens amalamulidwa kuti apititse patsogolo kugawidwa kwa maselo a tinthu ta sebaceous gland, kuwonjezera kuchuluka kwawo, ndikuwonjezera kupanga kwa sebum; Ndipo estrogen imachepetsa kutulutsa kwa sebum mwa kuletsa kupanga kwa androgens zamkati, kapena kugwira ntchito mwachindunji pa tinthu ta sebaceous glands.

Chowunikira khungu la Meicetingagwiritsidwe ntchito kuzindikira kuti nembanemba ya sebum ndi yathanzi kapena ayi. Ngati nembanemba ya sebum ndi yopyapyala kwambiri, ndiye kuti khungu lidzakhala losavuta kukhudzidwa ndi zinthu zakunja. Chithunzi chidzajambulidwa pansi pa kuwala kopingasa ndipo kutengera chithunzichiMeicetDongosolo limagwiritsa ntchito njira yopezera zithunzi zitatu - kukhudzidwa, malo ofiira, ndi mapu otenthetsera. Zithunzi zitatu izi zingagwiritsidwe ntchito pofufuza mavuto akhungu osavuta.
