Acne is caused by a normally harmless bacteria which lives on the skin. When a hair follicle gets blocked it causes either a white or black head and this bacteria can then infect the follicle and cause a number of acne related reactions including papules, nodules, pustules and cysts. lymecycline is an antibiotic in the family of tetracycline antibiotics and it specifically targets and destroys the bacteria which causes moderate to severe acne.
There are many myths around acne which are entirely untrue such as acne being contagious or being caused by dirty skin and poor hygiene. In terms of healing acne, the only way to get rid of it is to treat it effectively with medication such as the antibiotic lymecycline though the type of treatment recommended will be based on the acne you have.
