There are mainly three types of skin problems that occur:-
1.Spots/Acne- This is known to be the most common skin problem. This occurs when a hair follicle is stopped from growth due to the fact that it is blocked by oil. It can generally form a black spot.Sometimes, if germs get in, then it is known to be a swelled spot.
2.Moles- Generally the moles that are black or red and occur in large numbers are known as the normal moles. All other types are known to be harmful.
3.Tattoos- They are known to be harmful to our skin because the ink that is used goes deep into our skin which allows it to remain for a long time.This does not allow the skin to renew itself and some types of tattoos have been linked to skin cancer.
