assalamualaikum.
apa khabar iman anda? harapnya still baik lagi alhamdulillah :)
post kali ni nak cakap pasal kedut.hehe.
apa tu kedut? kedut tu adalah kondisi di mana berlaku pengecutan di bahagian yang lembut dan kenyal seperti kulit manusia. kedut biasanya terjadi bila kita sudah tua atau berendam lama2 dalam air.
(sumber: minda )
readers pernah mandi sungai,laut atau rendaam lama lama dalam bath tub tak?
*angguk*
ya! jika ya, pasti anda pernah merasai pengalaman kulit jari tangan dan tapak kaki mengecut. kenapa jadi macam tu? haa.. nak tau tak kenapa? kenapa ya? kenapa hanya di 2 spot tu sahaja kedutan jelas kelihatan? kenapa bukan di bahagian muka atau perut?
apa yang bakal saya kongsikan dengan readers adalah berkenaan assignment yang saya terima seminggu lalu. memandangkan saya telah melakukan pencarian dengan bertanya kepada pakcik google, apa salahnya saya berkongsi dengan readers jugak hehe. interestingkan ilmu Allah ni :)
okay saya start..
at our uppermost layer of skin cell, ada keratin protein. eh macam pernah dengar. hehe. ya. anda betul. keratin protein can be found at our hair. boleh juga dapat dekat kulit dan kuku. this keratin protein is a really good absorber of water. keratin protein can be densely found at our hands and feet.this is because keratin makes this areas tough to withstand hardwork. subhanAllah :)
so, if we immerse in the water for a long time, our keratin protein that found on the uppermost skin will absorb water more. lots of keratin at hand and feet make the absorption of water become increase.
then, skin will swell, but the skin layer beneath this upper skin do not swell :) it still attach to the upper layer and follow the increment. so, the increment yang sebabkan wrinkling of skin. because the skin try to arranged themselves with the increment.
different case if we are in sea water. ayaq laut kan masin,so mesti la banyak kandungan garam, yang mana kandungan air sangat rendah. hehe, jadinya, lebih masa diperlukan untuk proses pengedutan berlaku (ada ke nama proses cenggitu. hehe)
the conclusion is, if we immersed in both fresh water and sea water for a some period of time, we can see our skin wrinkle. but, the rate of wrinkling for both situation are different. fresh water is more faster as compared to sea water.
*done with my lab report !*
actually, there are many factors that contribute to why our skin wrinkle. kadang2 pasal low amount of sebum, genetic factors and others. and and and, severe expose to sun also can be one of the factor.
plus, if we are getting older, it is normal if our skin get wrinkle. That is the sign we are run out of time.
ya. peringatan Allah itu cantik. benar. sangat cantik.
p/s: maaf jika saya menulis dengan mencampuradukkan 2 bahasa. hee :P
