Almost everyone has experienced a rash at one time or another; that itchy, red patch of skin is unmistakable. However, if rashes keep appearing and you're not sure why, seeing a dermatologist is necessary to determine the rash's cause and the appropriate treatment. At Advanced Desert Dermatology in Peoria, AZ, Dr. Vernon Mackey sees many patients with rashes. Below, he discusses some of their common causes.
What is a rash?
A rash is the skin's reaction to a stimulus. It can change the way the skin looks and feels, but it is often reddish or pinkish colored due to increased blood flow to that area. The characteristics of a rash often help your dermatologist determine its cause. For example, the rash associated with measles starts at the head and spreads downward. It is usually flat and red but surrounded by clusters of small papules, or bumps.
An allergy is present when the body's immune system overreacts to a normally harmless substance. Food, medication, metals, animal dander and various plants can all cause allergic reactions, and exposure to many of these can cause a rash, which may or may not be itchy, to develop in response. Although there are medications that can help suppress immune reaction, your Peoria dermatologist may suggest avoiding that which triggers your allergies as the most reliable solution.
Rashes can also develop as a side effect to certain medications. This is a common occurrence when taking steroids; it often appears as an all-over reddening of the face. There are antibiotics that can also make the skin extremely sensitive to sunlight, increasing the likelihood of a severe sunburn.
Numerous other things can cause rashes: chafing, psoriasis or eczema, even pregnancy. Some people break out in a rash when they're nervous or anxious. The good news is that a quick consultation with your dermatologist can help diagnose most of these causes and they can be easily treated.

Your skin is your body's most prominent organ, making it essential to properly care for it, especially during the summertime when UV levels can wreak havoc on exposed skin. While basking in the sun can feel sensational, the effects of sun exposure may not be as agreeable over time. When you decide to hit up the beach in your new swimsuit, your dermatologist urges you to take extra precautions to protect your skin.
Many beach and pool goers often complain of sunburn, which is a visible reaction of the skin’s exposure to ultraviolet (UV) radiation, the invisible rays that are part of sunlight. Signs of sunburn may not appear for a few hours and the full effect to your skin may take up to 24 hours to appear, but when you have a sunburn, you will know it! Ultraviolet rays can also cause invisible damage to the skin. Excessive or multiple sunburns cause premature aging of the skin and can lead to skin cancer. According to your dermatologist, some of the most common symptoms of sunburn include:
- Swelling of the skin
- Dry, itching and peeling skin days after the burn
Sunburns typically heal on their own in a couple of weeks, but there are ways to alleviate the pain caused by them. It is often recommended that you take a cool bath or gently apply cool, wet compresses to the skin when sunburn develops. You many also take a pain reliever to help with the pain, but it is also important to rehydrate your skin to help reduce swelling by applying aloe.
Visit your dermatologist for more information on how to protect your skin this summer and to find out what to do when you suffer from sunburn. Remember, skin cancer is one of the most common forms of cancer in the United States, so protecting your skin this summer can help protect you for a lifetime.
While basking in the sun can feel sensational, the effects of sun exposure may not be as agreeable over time. This summer when you decide to hit up the beach or pool in your new swimsuit be sure to take extra precautions to protect your skin. Your dermatologist is available to provide you with tips on how to further protect your skin from harm.

Ouch! I think I have Sunburn
If acne has you feeling down, find out some of the best tips for reducing your breakouts.
Nothing is worse than waking up to a pimple. Sometimes it feels like they crop up practically overnight. They often show up at the worst of times, too: for a date, school pictures or your wedding. Of course, you may not realize that some of your daily habits could actually be promoting breakouts. Our Peoria, AZ, dermatologist, Dr. Vernon Mackey, pinpoints some things you may be doing wrong so you can maintain healthier skin.
Giving Up on Products too Soon
While everyone wants an overnight solution to acne, there just isn’t one. It takes skin time to respond to treatment, so patience is key when trying out products. Remember, any new acne product you try can take up to 12 weeks to see results. If you aren’t seeing results after 12 weeks, then you may want to talk to our Peoria skin doctor about another skincare line that might work better.
You Lather on Multiple Products
If one acne-fighting product might give you clearer skin then wouldn’t three products be even better? Hold up! By including too many different products at once you could actually just end up irritating and exacerbating your condition. Acne products can be drying, which can sometimes make acne worse. Play it safe and just stick to one acne-fighting cleanser or product at a time.
You Rub Your Skin Raw
Okay, maybe that’s an exaggeration, but you feel like the harder you scrub your skin the more bacteria and crud you’ll remove. Unfortunately, this aggressive scrubbing is actually doing more harm than good. Be kind and gentle to your skin when washing it, and remember that you don’t have to wash your skin more than twice a day.
You Want to Tackle the Issue Alone
While it’s certainly noble to try and solve acne all by yourself, you have to be able to admit when it’s time to get professional help. If you are experiencing frequent or painful pimples, if acne is affecting your self-esteem or if the treatments you are using just aren’t working, then it’s time to give us a call.
Are you frustrated by your acne? Looking for something that will finally tackle your acne problems? Then it’s time to turn to the skincare expert at Advanced Desert Dermatology in Peoria, AZ, to help you get the smoother, healthier skin you want.
The scar from when you fell off your bike as a child, from a recent car accident, from a surgery or even from acne may be a constant and painful reminder of events you'd rather forget. While you may not feel any physical pain from these wounds, scars can make you feel self-conscious or embarrassed, particularly if they are located on exposed skin.
The good news is dermatologists now have many treatments available to significantly reduce the appearance of scars, no matter what their cause was!
Scars are an abnormal healing response of the skin to injury, resulting in atrophic scars, which are skin depressions, or hypertrophic scars and keloids, which are elevated. The larger the surface area of skin affected, the greater the chance of a noticeable scar. Scars occur with equal frequency in men and women, although they most often develop between the ages of 10 and 30. While scars can be disfiguring physically, psychologically or both, significant itching and burning can also accompany hypertrophic scars and keloids.
How Do Scars Form?
Scars form when the dermis--the deep, thick layer of skin--is damaged. The body forms new collagen fibers to mend the damage, resulting in a scar. The new scar tissue will have a different texture and quality than the surrounding tissue. Scars typically form after a wound is completely healed.
There are a variety of different kinds of scars, but most are flat and pale. However, in cases when the body produces too much collagen, scars can be raised. Raised scars are more common in younger and dark-skinned people. Some scars can even have a sunken or pitted appearance, which occurs when underlying structures supporting the skin are lost. Some surgical scars may have this appearance, as do some scars formed from acne.
By visiting your dermatologist, you can better understand your scars and the treatments available to help diminish their appearance.
