If you have dark, crusty brown spots that are slightly raised, join the crowd — 83 million Americans have them. They are called seborrheic keratosis lesions, and they can be waxy, raised, flat, or like a wart. They’re ugly, but at least they’re benign.
No one is thrilled when these brown spots appear, but in most cases they’re just the result of aging. In the past, dermatologists could excise these spots, or freeze or burn them off, but that often left a scar in place of the spot.
Dr. Smith now offers a first-of-its-kind liquid treatment for seborrheic keratoses, Eskata. Eskata removes these unsightly spots in just one or two visits. Eskata only became available in April 2018 after receiving FDA approval in December 2017.
What Is A Seborrheic Keratosis?
Seborrheic keratosis (SK) is one of the most common noncancerous skin growths in older adults. They are brown, black, or light tan and usually appear on the face, chest, shoulders, or back. SKs are slightly elevated and can look waxy or scaly. They can be very small or as big as an inch in diameter.
Where Do Seborrheic Keratosis Form?
SKs can show up anywhere on your body, except the palms, soles of the feet, and the mucous membranes. They are most common on the face, neck, and hairline, however.
What Causes Seborrheic Keratosis To Form?
The cause of SKs is unknown, but they are not thought to be related to sun exposure as pre-cancerous lesions (such as actinic kerasoses) are. SKs are normally painless and don’t require treatment or even attention. SKs are not contagious, but do tend to run in families, so there is likely some sort of genetic tendency toward developing them.
What Is Eskata?
Eskata is a high-concentration (40%) hydrogen peroxide-based topical solution that was developed specifically to remove raised seborrheic keratoses. Eskata includes an applicator for targeted treatment of SKs. The FDA approved Eskata to treat SKs on December 14, 2017.
How Does Eskata Work?
After Dr. Smith has determined your brown spot is not cancer or pre-cancerous, she carefully applies the highly concentrated hydrogen peroxide liquid to each targeted lesion with the included applicator. Then she waits one minute and reapplies Eskata. She repeats this four times to complete the treatment. Afterwards, the lesion will scab over and then peel off. You’ll see Dr. Smith again after around 3 weeks. If your treated raised SKs are not clear, she can apply one additional treatment. Some SKs are gone after one treatment, but others may require a second treatment. They may not completely clear, but should dramatically be reduced in visibility.
Is There Recovery Time With Eskata?
There isn’t any recovery necessary. Treatments are completely topical. You simply wait for Eskata to cause the lesion to scab and then peel. You may opt to have a small bandage over the SK while it is being treated with Eskata for aesthetic reasons.
What Are The Side Effects With Eskata?
Eskata is not to be used near the eyes. Eye problems can occur if this product gets in the eyes. These include ulcers or small holes in your eyes, scarring, redness, irritation, eyelid swelling, severe eye pain, and permanent eye damage, including blindness.
The most common side effects with Eskata are itching, stinging, crusting, swelling, redness, and scaling. These are all localized to the treated area.
How Much Does Eskata Cost?
The cost of this product varies depending on the amount used. Dr. Smith will discuss the costs with you and give you an estimate, depending on the SKs you seek to treat.
