Is this grammatically correct? What does it mean and can it be rephrased? I have a very sensitive skin and my skin reacts with the weather

The sentence has a small grammatical error; it should be "I have very sensitive skin" instead of "I have a very sensitive skin." The use of "a" is incorrect here because "skin" is an uncountable noun. The meaning of the sentence is that the speaker's skin is easily affected or irritated by changes in the weather. Here are a few rephrasings of the sentence: 1. "I have very sensitive skin that reacts to the weather." 2. "My skin is very sensitive and tends to react to weather changes." 3. "I have sensitive skin that responds to different weather conditions."
