The article talks about how to have healthy and glowing skin. The doctor says that too much sun can be bad for our skin because it can damage our body's building blocks called DNA. So, we should use sunscreen when we go outside and protect our skin from the harmful rays of the sun.

The doctor also talks about how smoking is not good for our skin or our whole body. Smoking can make our blood carry less oxygen to our skin, which makes it look bad and age faster. The doctor advises us to avoid smoking and things that can harm our skin like the sun, a bad diet, and being lazy.

Lastly, the doctor mentions something called cannabis, which some people use as medicine or for fun. He says we need to be careful because it's still new and not well understood yet. But he thinks it might have some good effects on our skin too. Read from source...

1. The author does not mention any scientific evidence or references to support the claims made in the article, such as the effects of ultraviolet radiation on DNA, the role of cardiovascular system in skin health, and the impact of cannabis on skin. This makes the article unreliable and lacking credibility.
2. The author uses emotional language, such as "surprising truth", "glowing skin", and "photoaging", to persuade the reader without providing clear or logical arguments. This is a manipulative technique that can confuse or mislead the audience.
3. The author does not consider the possibility of other factors influencing skin health, such as genetics, lifestyle choices, dietary habits, and environmental conditions. This creates a one-sided and incomplete view of the topic, ignoring potential causes and solutions for different skin types and issues.
4. The author focuses mainly on the negative aspects of smoking, cannabis, and tanning, while neglecting to mention any benefits or advantages that these substances or activities might have for some people's skin. This is a biased and unbalanced perspective that does not acknowledge the diversity and complexity of human skin and preferences.
5. The author ends the article with a question from the reader, but does not provide any answer or explanation, leaving the reader unsatisfied and confused. This shows a lack of professionalism and competence in addressing the reader's needs and expectations.
