英文小作文：

My favorite color is blue, which is why I am always drawn to things that have a hint of this color. However, recently I have noticed that my skin has started to show signs of discoloration, which has caused me some concern. I have tried various products to help reverse this change, but so far nothing has worked as effectively as I would have liked. I am hopeful that this issue will resolve itself soon, but until then, I am trying to stay positive and focus on other aspects of my appearance that I am more confident in, such as my smile and my personality. I am reminded that beauty is not just skin deep, but rather it is a combination of many factors that make someone truly beautiful. So, while my skin may be changing, I am still confident in the overall image that I present to the world.
