A dermatologist is a doctor who specializes in caring for the skin, which is also the largest organ on the human body. Unfortunately, many people go their entire lives without ever seeing a 
dermatologist. As a result, these people are more prone to developing skin problems that go untreated, such as eczema, rosacea, or even a form of skin cancer. Specifically, there are a few tell-tale signs that it may be time to see a dermatologist Palo Alto area.

A Mole Has Changed Shape or Size
One of the first visible signs of skin cancer is that of a mole that has suddenly changed shape or grown in size. Sometimes, this symptom even occurs before skin cancer is present. Therefore, it's important for people to be mindful of the moles on their bodies and keep an eye on them. Any changes or deviations from a mole's normal state indicate the need to see a dermatologist. Specifically, a biopsy may need to be performed.
Sun Sensitivity Has Developed
Over time, the body can become more sensitive to the sun. In fact, some people even develop a sun allergy as they age. For many, a sun allergy means that an area of skin (usually on the chest or arms) breaks out into a rash or raised bumps that can be very uncomfortable. Those who have recently developed more sun sensitivity would be well served to see a dermatologist for an official diagnosis and to explore possible treatment options.
Presence of a Rash or Itchy Area
Anytime a rash or itchy area of the skin persists for more than a few days without relief, it's a good idea to see a dermatologist. There are lots of things that can cause rashes, so only a 
dermatologist will be able to assess the situation and provide the right treatment option for relief.

Never Been to a Dermatologist
Finally, those who are in their 20s or older and have never been to a dermatologist would be wise to schedule a general check-up, even if there are no obvious signs of a skin problem. Most health insurance plans will cover at least one visit to a dermatologist each year, even if it's not for a known medical problem. From there, one can feel better in knowing that they're taking good care of their body's biggest organ, the skin!
