Does that little skin growth keep snagging on your necklace, rubbing under your bra strap, or showing up in every close-up photo? Many bumps and spots are harmless, but they can still be annoying, uncomfortable, or make you feel self-conscious.
Electrodesiccation is a quick, in-office treatment that can safely remove certain benign skin growths using controlled heat from an electrical current. On this page, you’ll learn what electrodesiccation is, what it can treat, what to expect during your visit, and how to care for your skin afterward.
At ProDerm Skin & Surgery in Austin, electrodesiccation is performed by Dr. Sydney Larkin Proffer, a board-certified dermatologist with advanced fellowship training in both Mohs micrographic surgery and cosmetic dermatology. Her background supports careful lesion selection, precise technique, and results that prioritize both skin health and appearance.
What Is Electrodesiccation?
Electrodesiccation is a minor dermatology procedure that uses a small instrument to deliver a controlled electrical current. The current gently dries out and destroys targeted tissue, allowing the treated growth to be removed or to naturally slough off as the area heals.
Because the treatment is focused and fast, it’s commonly used for select superficial lesions when your dermatologist determines it’s appropriate.
What Can Electrodesiccation Treat?
Electrodesiccation may be used to treat a range of noncancerous growths and surface-level concerns. Your provider will evaluate your skin to confirm what the spot is before recommending any removal.
- Skin tags (acrochordons)
- Seborrheic keratoses (waxy, “stuck-on” growths)
- Cherry angiomas (small red bumps)
- Select benign lesions that are raised or irritated
- In some cases, certain precancerous lesions when clinically appropriate
If a spot looks unusual, changes over time, or has concerning features, your dermatologist may recommend a biopsy instead of electrodesiccation to ensure an accurate diagnosis.
Benefits of Electrodesiccation
- Quick treatment: often completed in minutes
- Minimal bleeding for many lesions
- No stitches needed for most treatments
- Little to no downtime
- Can improve comfort and cosmetic appearance
The best results come from choosing the right lesions for the right method—something a trained dermatology team is uniquely equipped to do.
What to Expect During Your Appointment
First, your provider examines the area and confirms the diagnosis. If electrodesiccation is a good fit, the skin is cleaned and numbed with local anesthetic.
Next, the instrument is applied to the lesion in brief, controlled touches. You may feel slight pressure, but most patients are comfortable once numb. Multiple spots can often be treated in the same visit, depending on location and size.
Recovery, Aftercare, and Results
After treatment, the area may look pink or slightly swollen, then form a small scab. This is normal and part of healing.
- Keep the area clean and dry as instructed
- Avoid picking or scratching the scab
- Use petroleum jelly or other recommended ointment to support healing
- Protect the area from sun exposure to reduce dark marks
Most patients heal in about 1–2 weeks, though larger spots may take longer. The final appearance continues to improve over several weeks.
