What causes lichen planus?
Lichen planus is not contagious and cannot be spread from person to person. In fact, it typically appears when the immune system starts attacking the skin or mucous membrane. Certain things can trigger it including:
- Certain OTC pain medications (e.g. ibuprofen)
- Medications used for arthritis, hypertension, or cardiovascular disease
- Hepatitis C
- Viral infections
- Certain allergens
- Genetics
- Stress
- Certain chemicals or metals
Should I see a dermatologist?
If you have developed a purple rash or bumps that resemble lichen planus it’s worth it to pay a visit to your dermatologist to find out what’s going on, especially if you notice any unusual bumps on the genitals.
To determine that you do have lichen planus, we will need to biopsy some skin cells to diagnose lichen planus and to also determine whether it’s being caused by an underlying infection or an allergen. From there, further testing may be needed.
How is lichen planus treated?
So, you found out from your dermatologist that you have lichen planus. Now what? In some cases, this condition may just go away on its own; however, it’s important to recognize that there is no cure for lichen planus but there are ways to help alleviate certain symptoms such as burning or pain. Common treatment options that your dermatologist can recommend or prescribe include,
- Antihistamines: To help with itching
- Corticosteroid creams: To reduce inflammation and redness
- Oral or injectable steroids: This treatment is more effective for persistent, recurring, or more severe bumps
- Photochemotherapy: Light therapy can be effective for treating oral lichen planus
Even the healthiest of the skin may not always look its best due to aging, acne scars, and sun exposure. If you wish to rejuvenate your face to have a younger, brighter look, talk to your dermatologist at Dawson Dermatology in Honolulu, HI. Drs. Douglas Chun, Kevin Dawson, and Sarah Grekin offer the latest in medical and aesthetic dermatology. Microdermabrasion is one of their easiest and most effective services.
Just what is microdermabrasion?
Microdermabrasion is a medically-supervised aesthetic treatment that exfoliates the skin on the neck and face. The gentle procedure employs a mildly abrasive cream and a small handheld tool to remove the top layer of skin, revealing smoother, more evenly pigmented, and brighter skin beneath. Microdermabrasion promotes skin cell growth as well.
Your dermatologist at Dawson Dermatology in Honolulu, HI, recommends microdermabrasion for healthy men and women who wish to reduce the appearance of:
- Fine lines and creases
- Areas of hyperpigmentation (melasma) on the cheeks and neck
- Acne scars (Microdermabrasion is not advisable for active acne.)
- Age spots
- Dullness
Microdermabrasion also removes excess oil, dead skin cells, and whiteheads/blackheads.
The American Academy of Dermatology reports that people of all skin textures may undergo this in-office procedure successfully. There is no appreciable downtime, and you may see only slight redness and puffiness afterward. Also, as it heals, your skin may feel more sensitive to the sun.
Is microdermabrasion permanent?
No, it is not permanent, but the treatment yields significant results. However, one treatment is insufficient and results do not last indefinitely. Most people have several weekly treatments, and likely, your dermatologist will ask you to use a moisturizer before and between your treatments at Dawson Dermatology. Sunscreen lotion of SPF 15 or high is a must-have on a continuing basis. Microdermabrasion may be just part of a comprehensive skin makeover.

Most people don’t know what impetigo is. Maybe you haven’t even heard of it. This contagious bacterial skin infection is most often seen in babies and children; however, adults can catch this infection, too. Dermatologists often see a rise in impetigo cases during the summer. How does impetigo even happen in the first place?
Well, our skin is home to millions of bacteria. Most of them are actually good bacteria that help you stay healthy; however, bad bacteria can develop on the skin too. If these bad bacteria can get into a wound or opening in the skin, this can cause impetigo.
What are the symptoms?
Impetigo causes red bumps mostly on the arms, legs, and face. These bumps will eventually turn into blisters that will crust over. The skin under and around the blisters may look raw. At first, you may only notice one or two spots; however, the condition will continue to spread. Bumps may itch or also be tender.
Who is at risk for impetigo?
As we said, we often see this condition in children and infants; however, certain factors can also put adults at risk. You may be more at risk for impetigo if you have been diagnosed with,
- Scabies
- HIV/AIDS
- Liver conditions
- Diabetes
- Eczema or dermatitis
Since many skin conditions cause painful blisters to form it’s important to see a dermatologist right away for a proper diagnosis. When you come into the office, our skin doctor will ask you questions about your symptoms and medical history to help rule out what conditions it could be. A physical examination performed by a qualified dermatologist is often all that’s needed to make a diagnosis; however, we may collect fluid from the blister to look for the presence of bacteria.
How do you treat impetigo?
It’s important to see a doctor for treatment because impetigo will require antibiotics. Depending on the severity of the blisters, your dermatologist may simply prescribe an antibiotic cream, while those with more widely affected areas or more severe symptoms may require oral antibiotics. Once you start taking the medication you should recover within a week.
If you or your little one is dealing with symptoms of impetigo you must see a dermatology professional right away for a proper diagnosis and treatment.
