Identifying the cause of red spots on skin can prove to be difficult. Sometimes red spots and red bumps on your skin may mean nothing and go away without any treatment. Other times though, red spots, bumps, dots or patches may be signs of something more serious. There are a lot of different things that can cause red bumps on your skin and they can be really annoying if they end up being itchy. Keep in mind that this is a general list and is not meant for self diagnoses.
The most common reason for having red spots on your skin is due to acne. It is estimated that 90% of people have suffered from acne at some time in their life. The problem is that people pick at the acne and zits to try and get rid of them. This can lead to a red or brownish area around where the acne was. The good news is that the redness from acne is not permanent and will fade given a little bit of time.
The second most common reason for having red spots on skin is bug bites. When you get bitten by a bug such as a gnat, mosquito or flea they inject their saliva into you. This causes your skin to form a red spot or bump and it will usually be very itchy. It is wise NOT to scratch at any red sores you have because that tends to make them worse rather than better.
Having any form of dermatitis is likely to leave red spots on your skin. These can range in variety and be very mild or extremely bad. Dermatitis is basically just a condition of the skin that has been caused by a reaction. Some common causes of dermatitis include: infections, allergic reactions, skin conditions, poison ivy or poison oak and many other things.
If you have a kid with multiple red itchy bumps on their skin then they most likely have Chickenpox. Chickenpox is a viral infection in which a person develops extremely itchy blisters all over the body. It used to affect almost all children but in recent times it has been brought under control thanks to the Chickenpox vaccination. If your child does have chickenpox then there is no need to worry, it only lasts a few days and will generally go away on its own.
The last cause I want to discuss is called folliculitis. Folliculitis is inflammation of one or more hair follicles. It can happen anywhere on the body and may or may not be itchy. The cause of folliculitis is when your hair follicles get damaged by rubbing against your clothing or from shaving. When they get damaged it allows bacteria, usually staph, to infect the follicle and then cause some red spots on skin.
These are just some of the most common reasons for red spots or red bumps to appear on your skin. There are many many many other possibilities so keep that in mind when looking for the cause of your red dots on skin. Other things to keep in mind are if you started using any new detergents or soaps lately, started eating any different foods or have come in contact with any strange plants.
If you are still unsure about the reasons you have red areas on your skin then I would always recommend seeing a doctor or specializes in skin care such as a dermatologist. They are a medical professional and should be able to help you with all your skincare needs!
