Warts are a type of skin lesion that occur in different ways and appear in different parts of the body. They are usually harmless and can be caused by the Human Papilloma Virus (HPV).
Blackheads and spots on the skin, although they are not as unpleasant as warts, also represent a particularly aesthetic problem in those cases that appear to be chronic. The spots are most commonly caused by pimples and blackheads. Blackheads can occur for many reasons, such as bacteria, exposure to pollutants, hormonal changes, make-up with expired date or of poor quality, lack of hygiene and excess of fat in the skin.
