Cherry angiomas are benign. The real question is which removal method costs less, causes less discomfort, and works reliably without requiring a clinic visit. This page compares the plasma pen and cryotherapy side by side on mechanism, downtime, pain, and suitability so you can choose the right path for your situation.
For a broader look at how the plasma pen stacks up against other modalities, see our plasma pen vs laser comparison. This page is the cryotherapy question, answered in full.
Key takeaways
Both methods work. The difference is where you do it and what the skin pays afterward.
- Clinical cryotherapy uses liquid nitrogen to freeze the angioma; the plasma pen uses a targeted ionized arc to carbonize it.
- Cryotherapy requires a dermatologist visit; the plasma pen is an at-home device.
- Cryotherapy carries a higher hypopigmentation risk, especially in darker skin tones, according to published dermatology literature.
- Both treatments typically resolve a cherry angioma in one to three sessions for small lesions.
- OTC freeze kits are not the same as clinical liquid nitrogen cryotherapy and are less studied for cherry angioma removal.
How cryotherapy works on cherry angiomas
The mechanism
Cryotherapy destroys tissue by rapid freezing. When liquid nitrogen (approximately -196 degrees Celsius) contacts the cherry angioma, ice crystals form almost instantly inside and around the vascular cells. The crystals rupture cell membranes, and the body then reabsorbs the destroyed vascular tissue over the following one to three weeks.
According to the American Academy of Dermatology, cryotherapy is a well-established in-office treatment for benign vascular lesions. The freeze must be precise: too shallow and the angioma persists; too deep and the risk of post-inflammatory hypopigmentation rises, particularly in skin of color.
What a clinical cryo session looks like
A dermatologist applies liquid nitrogen via a spray canister or cotton-tipped applicator directly to the angioma surface. The freeze typically lasts 5 to 10 seconds. Patients report a sharp cold sting during the application and a burning sensation immediately after. A blister or crust commonly forms within 24 to 72 hours. The lesion typically resolves in 1 to 3 weeks. For larger angiomas (above 5 mm), a second session may be needed.
Liquid nitrogen is classified as a medical gas and is not available for consumer purchase. This makes clinical cryotherapy a derm-office-only procedure.
How the plasma pen works on cherry angiomas
The mechanism (plasma ionization)
The plasma pen delivers a controlled arc of ionized gas directly to the cherry angioma surface. The plasma energy carbonizes the superficial vascular cluster at the cellular level without breaking the surrounding skin barrier. This is mechanically analogous to electrodesiccation, which the AAD recognizes as an effective treatment for cherry angiomas, though the plasma pen is an at-home beauty device and not a medical instrument.
A small protective scab forms over the treated spot. It falls off on its own between Day 3 and Day 7. By Week 2 to Week 3, the skin underneath reveals clean, clear results. Treatment time per angioma is approximately 5 minutes.
The at-home difference
Because liquid nitrogen is clinic-restricted, self-treatment via cryotherapy is not a real option. The plasma pen fills that gap. It has 9 adjustable power settings, allowing you to calibrate the treatment intensity to the size and depth of each angioma. No appointment, no clinic, no commute.

Plasma pen vs cryotherapy: the side-by-side
The table below covers the key decision variables. The plasma pen column is highlighted because this cluster focuses on at-home options. The OTC freeze kit column is included for completeness, not as a recommendation: consumer freeze kits use nitrous oxide at much lower temperatures than clinical liquid nitrogen, and their effectiveness on cherry angiomas specifically is not well documented in the literature.
What the clinical evidence says
Clinical data on cryotherapy for cherry angiomas
According to a study published in the Journal of Dermatological Treatment, cryotherapy and electrodesiccation were both effective for cherry angioma removal, with most lesions clearing after one to two sessions. The study noted that post-treatment hypopigmentation occurred at a higher rate with cryotherapy, particularly in patients with Fitzpatrick skin types IV through VI. These findings are consistent with guidance from the Mayo Clinic, which notes that cryotherapy for benign skin lesions carries a risk of temporary or permanent skin lightening at the treated site.
For cherry angiomas specifically, cryotherapy is considered a standard clinical option. The AAD does not list cryotherapy as contraindicated for cherry angiomas, but recommends clinical assessment before treatment to rule out other vascular lesions that require different management.
Plasma pen for vascular lesions
The plasma pen is a consumer at-home device, not a medical instrument, and does not claim to provide medical treatment. Its mechanism of action on cherry angiomas, targeted surface ionization destroying the superficial vascular cluster, is mechanically similar to electrodesiccation, which dermatology literature recognizes as effective for these lesions.

Pain, downtime, and side effects: the honest comparison
What to expect with cryotherapy
Patients typically report a sharp cold sting during the freeze (5 to 10 seconds) and a burning or throbbing sensation in the 20 to 30 minutes afterward. Redness and swelling are common for 24 to 48 hours. A fluid-filled blister may develop and burst within one to three days. According to published dermatology references, hypopigmentation (light spot where the angioma was) can persist for weeks or become permanent, with elevated risk in darker skin. Multiple visits are sometimes required, each carrying a repeat exposure to these effects.
What to expect with plasma pen
During the 5-minute treatment, most users describe a mild warmth or brief sting at the spot. A small scab forms at the surface and falls off on its own between Day 3 and Day 7. No picking or scrubbing is needed. By Week 2 to Week 3 the treated area shows clear skin. The 9 adjustable power settings let you dial in intensity to the size of each angioma, which helps minimize both discomfort and the risk of over-treatment.
When to see a dermatologist first
Not every red spot is a cherry angioma. Before treating at home with any method, confirm the lesion is a benign cherry angioma. Book a dermatologist if:
- The spot bleeds on its own or when lightly touched.
- The border is irregular or changing in shape over weeks.
- The lesion is growing rapidly or has an unusual texture.
- You have multiple new spots appearing quickly, which may warrant evaluation for underlying causes.
- You are not confident in the identification.
Cryotherapy is a proven clinical option. The plasma pen is the proven at-home option. The gap between them is the clinic visit, the cost per session, and the hypopigmentation risk in darker skin.
Which option fits your situation
The right choice depends on three factors: access to a dermatologist, skin tone, and how many angiomas you are treating.
Choose the plasma pen if
- You want to treat at home on your own schedule, without a clinic visit or appointment.
- You have one to several small cherry angiomas that are clearly confirmed benign.
- Cost efficiency matters: a one-time device purchase covers multiple angiomas now and future ones.
- You want adjustable control over treatment intensity.
Choose clinical cryotherapy if
- You prefer a dermatologist to perform the procedure.
- You have a large or deep angioma that warrants clinical assessment before treatment.
- You are already seeing a dermatologist for another reason and can add it to the visit.
A note on skin tone
Published literature, including references cited by the American Academy of Dermatology, notes a higher hypopigmentation risk with cryotherapy in skin of color (Fitzpatrick types IV-VI). If this applies to you, discuss this risk specifically with your dermatologist before choosing cryotherapy. The plasma pen's adjustable settings provide more granular control, which may reduce this risk at home, though individual results vary and self-treatment always carries its own considerations.

The bottom line
Cryotherapy is a well-established clinic procedure for cherry angiomas. It works, it is fast in the chair, and dermatologists have used it for decades. The tradeoffs are the office visit, the cost per session, and an elevated hypopigmentation risk in darker skin that published literature has documented.
The plasma pen is the at-home answer to the same problem. One device, adjustable settings, no appointment, no commute, a 5-minute treatment per spot, and a predictable scab-to-clear timeline of Day 3-7 through Week 2-3. For anyone who wants to handle confirmed cherry angiomas on their own schedule, it is the practical choice.
