When you have a cold, your face may swell as your body fights off germs, increasing blood flow to the area. This extra blood can make your face look puffy. Rest, hydration, and a cold compress can help reduce the swelling. However, if it persists or gets worse, it's important to consult a doctor, as it could indicate something more serious than a regular cold.

You may have a combination of shiny skin, hyperpigmentation, pimples on your forehead, and spots on your cheeks. Overactive oil glands are a magnet for pimples which consecutively leave dark marks. Stress, hormones, and your diet could all contribute to making it severe. Tanning or irritating your skin might be responsible for brown spots. To fix your issue, gently clean it every day using cleansing products; you can get some over-the-counter drugs meant for treating acne then apply them as instructed, and protect it against the sun by wearing sunscreen all the time.

You may have a condition named acanthosis nigricans. It can bring about thick, dark, smelly skin in places such as the underarms, and neck.

Adopting a healthier lifestyle is necessary to eat a well-balanced diet and exercise can help improve this condition.
