Need to write a 300-word report about the structure and biochemistry of the stratum corneum and relate it to the function of the barrier. There is no introduction and conclusion included in this writing so you crucially need to get straight to the point and be concise as it is only limited to 300 words. I have also attached a file on the marking criteria you need to follow to aim for good grades. As you can see, the first and second 'content and ideas' rubric is crucial to follow as it is worth at least 30 points.There are two main parts to this writing:Comprehensively outline the structure and show a sophisticated understanding of the biochemistry of the stratum corneum and explain why this is a good barrier (always relate everything you are saying to the barrier function). (This part is 60% of what is explained in this writing, so focus more on this more than the other which is written below)Explain how the skin treatment 'crystal microdermabrasion' disrupts/impairs the barrier and how it recovers following this procedure. (again, do not write anything about the procedure process, get straight to the point). (Could be a couple of sentences or a very small paragraph).Everything explained has to be related back to the function of the barrier (if it doesn't, then don't include it in this writing). Relate at all times.Everything said needs to be explained in-depthly and in detail. (Why and how) But as scientifically as possible, do not put unnecessary words as you need to think about the word count.in regards to the marking criteria rubric, do not worry too much about the 'referencing' and 'presentation'. Do not use images. and you need at least 15-20 references from peer-reviewed journal articles. No less than 15. They need to be relevant; the peer-reviewed journal articles have to be no less than 5 years old. Because I attend an Australian school, those are the rules of good research. Good research is needed!!As this is 300 words, 25 words more than the general order requirement, I will pay extra once completed and if this is outstanding quality, I will give a good tip.
