This condition occurs when your skin produces excess pigment, resulting in dark spots. It often appears after a pimple has healed. To treat it, you can use products containing ingredients like vitamin C or retinol, which can help fade the dark spots over time. Remember to always apply sunscreen to protect your skin from further damage.

Jellyfish stings are common and can leave scars, swelling, and itching even after the pain subsides. Applying antihistamine creams can help with itching and oral antihistamines are recommended for swelling. If symptoms persist, a local methylprednisolone injection may be considered. It's best to avoid swimming and running until the scars heal to prevent further irritation.
