Have to use transitional words for your work to flow. In the beginning middle end. you don't want to seem as if it all goes together, you don't need evidence or commentary that doesn't make since. transition words are very needed to help your paper make since and flow all together.
what do you mean by this I don't understand
I think so, but not really but dark spots usually go away over time, instead there are creams made to use for the dark spots and it helps quite a lot. I can list some for you that I use such as Mdacne and hydroquinone cream I prefer hydroquinone cream more since its more effective and cheaper. Hope this helps:) Have a good day/night.
