Ka ili o ka ili ——Malama ili

Ke emi nei ka Hormone me ka makahiki, me ka estrogen, testosterone, dehydroepiandrosterone sulfate, a me ka hormone ulu. Nui nā hopena o nā hormones ma ka ʻili, me ka hoʻonui ʻana i ka collagen content, hoʻonui i ka mānoanoa o ka ʻili, a me ka hoʻomaikaʻi ʻana i ka ʻili hydration. I waena o lākou, ʻoi aku ka ʻike o ka mana o ka estrogen, akā ʻaʻole maopopo ʻole ke ʻano o kona mana i nā cell. ʻO ka hopena o ka estrogen ma ka ʻili e ʻike nui ʻia ma o nā keratinocytes o ka epidermis, fibroblasts a me nā melanocytes o nā dermis, a me nā pūnaewele lauoho lauoho a me nā kelepa sebaceous. Ke emi nei ka hiki o ka wahine ke hana i ka estrogen, e wikiwiki ana ke kaʻina o ka ʻili. ʻO ka nele o ka hormone estradiol e hoʻemi i ka hana o ka papa basal o ka epidermis a hoʻemi i ka synthesis o nā collagen a me nā elastic fibers, nā mea āpau e pono ai no ka mālama ʻana i ka elasticity ʻili maikaʻi. ʻO ka emi ʻana o nā pae estrogen postmenopausal ʻaʻole wale ke alakaʻi i ka emi ʻana o ka ʻili collagen maʻiʻo, akā ʻo ka metabolism o nā cell dermal ka hopena e ka postmenopausal haʻahaʻa estrogen pae, a hiki ke hoʻololi koke ʻia kēia mau hoʻololi e ka noi topical o ka estrogen. Ua hōʻoia nā hoʻokolohua e hiki i ka estrogen topical wahine ke hoʻonui i ka collagen, mālama i ka mānoanoa o ka ʻili, a mālama i ka ʻili o ka ʻili a me ka hana pale o ka stratum corneum ma ka hoʻonui ʻana i ka glycosaminoglycans acidic a me ka hyaluronic acid, i mālama ai ka ʻili i ka elasticity maikaʻi. Hiki ke ʻike ʻia ʻo ka emi ʻana o ka hana o ka ʻōnaehana endocrine o ke kino kekahi o nā mea koʻikoʻi e hoʻoikaika ai i ka hana ʻelemakule o ka ʻili.

ʻO ka hoʻohaʻahaʻa ʻana mai ka pituitary, adrenal, a me nā gonads e kōkua i nā loli ʻano o ke kino a me ka ʻili phenotype a me nā ʻano hana e pili ana i ka ʻelemakule. ʻO ka nui o ka serum o 17β-estradiol, dehydroepiandrosterone, progesterone, hormone ulu, a me kā lākou hormone downstream insulin growth factor (IGF)-I emi iho me ka makahiki. Eia naʻe, ua emi nui nā pae o ka hormone ulu a me ka IGF-I i loko o ka serum kāne, a hiki i ka emi ʻana o nā pae o ka hormone i kekahi mau heluna kanaka i kahi pae kahiko. Hiki i nā hormones ke hoʻopili i ka ʻili a me ka hana, ka ʻili permeability, hoʻōla, cortical lipogenesis, a me ka metabolism ʻili. Hiki i ka estrogen replacement therapy ke pale i ka menopause a me ka ʻelemakule o ka ʻili.
