3. Egogetous na Exogetous:

Gusaza kuruhu biterwa na endogenous na exogen gusaza. Igikorwa cyo gusaza kiganisha ku kugabanuka kwuruhu rwuruhu rwuruhu hamwe nimikorere ya physiologique. Gusaza endogenous bigenwa cyane na gen, kandi ntigisubirwaho, kandi bifitanye isano na radical yubusa, glycosylatine, uruhu rworoheje kandi rwamagana rufite igipimo cyo gutakaza imbaraga. Kuzamura imitwe ya Edrinsic biterwa ahanini nizuba, bifitanye isano no kunywa itabi, umwanda wibidukikije, kwita kuruhuke, uburemere bwuruhu, nibindi.

4. UV:

80% yo gusaza yo mumaso iterwa nizuba. Uv Kwangiza uruhu ni inzira yo kwigunga, gukurikira inshuro, igihe no gukaza guhura nizuba, kimwe no kurinda uruhu.
