Plasma Pen vs Doing Nothing: Will the Spot Get Worse?

Plasma Pen vs Doing Nothing: Will the Spot Get Worse?

An honest look at what happens when you leave benign skin lesions alone versus treating them, and how to decide which approach is right for your situation.

Plasma Pen vs Doing Nothing: Will the Spot Get Worse?
Published 2026-05-18 · Reviewed by OcuraLife Skin Experts · 7 minute read

Most benign skin spots, including cherry angiomas, skin tags, and milia, will not get worse in a dangerous sense. They will not become cancerous and they will not spread to other parts of your body. What many of them do over time: multiply slowly, enlarge slightly, or become more noticeable. Treating now means the spot is gone in under three weeks. Waiting means it will likely still be there next year, and possibly joined by a few more.

For a full breakdown of what the plasma pen actually does and whether it works, see our complete plasma pen guide.

Key takeaways

Stable does not mean permanent. Most spots stay harmless, but many multiply with age.

  • Cherry angiomas, skin tags, milia, and sebaceous hyperplasia are benign: none will become cancerous on their own.
  • Most spots are stable in size, but many people develop more of the same type over years.
  • Treating now with a plasma pen removes the specific spot permanently in 7 to 21 days.
  • Waiting is a valid choice, but any spot that changes, bleeds, or grows rapidly needs a dermatologist first.
  • The plasma pen is the at-home tool built for this. Five minutes per spot, results clear by Week 2 to 3.

What actually happens when you leave a benign spot alone

The behavior of benign spots over time depends on the type. Here is the honest picture for the four most common ones.

Cherry angiomas

Cherry angiomas are stable once formed. Most will not grow significantly in size over months or years. What does change: adults in their 40s and 50s commonly develop more of them over time. It is not unusual to have one at 38 and six by 45. According to the American Academy of Dermatology, cherry angiomas are benign vascular overgrowths with no malignant potential. The individual spot is safe to leave. The pattern of new ones forming is the part most people find frustrating over time.

Skin tags

Skin tags are generally stable in size once formed. The connection between skin tags and insulin resistance (noted by the Mayo Clinic) means people who develop them often develop more over the years, particularly in friction zones like the neck, underarms, and under-breast area. An individual skin tag left alone will typically stay the same size indefinitely. It will not become cancerous. But the underlying factors that cause them do not go away on their own, which is why many people go from two tags to ten over a decade.

Milia and sebaceous hyperplasia

Milia (the tiny white grains under the skin) can resolve on their own in some cases, particularly in younger skin. Sebaceous hyperplasia bumps (soft yellow bumps with a central dimple) tend to persist. On oilier or more seborrheic skin, both can multiply after 40. Neither spreads in a harmful sense. But left alone, they tend to stay or accumulate rather than clear on their own.

Can spots multiply if left untreated?

The spot itself will not seed new spots. A cherry angioma does not cause other cherry angiomas to form. A skin tag does not reproduce. What does happen: the body conditions that produce them, hormonal shifts, friction, elevated insulin, aging sebaceous activity, continue operating whether or not you remove individual spots. Most people who have three skin tags at 40 will have more by 50. Not because one became many, but because the same body keeps making them. Treating the ones you have now removes those specific lesions permanently. It does not prevent new ones from forming, but it does reduce the current count and the ongoing low-level awareness of each spot every time you look in the mirror.

When waiting is fine and when it is not

Waiting is absolutely fine if the spot is stable, has looked the same for months, and is not bothering you. Many people choose to leave benign spots untreated indefinitely. That is a valid and safe choice for spots that are confirmed benign and unchanging.

Waiting becomes the wrong call when the spot shows any of these:

  • Growing or changing in size, shape, or color over weeks to months
  • Bleeding without being touched
  • Itching persistently without an obvious cause
  • Developing an irregular, rolled, or ulcerated border
  • Looking pearly, glassy, or translucent rather than matte
  • In a location where friction is chronically irritating it

Any of those signals means dermatologist visit first, no at-home treatment until the spot is identified and cleared.

When you must see a dermatologist first

A spot that bleeds on its own, has visible tiny blood vessels running across the surface, looks pearly or translucent, or has been slowly changing over months is not a candidate for at-home treatment until a professional has looked at it. Per MedlinePlus, skin conditions that change over time are worth medical review. For the full safety picture on at-home plasma pen use, see is the plasma pen safe? If you are not certain what the spot is, identify it before you treat it.

Safety first

Never use a plasma pen on a spot that bleeds without trauma, has visible blood vessels on the surface, is pearly or glassy in appearance, or has been changing over weeks to months. Those are flags for a dermatologist evaluation, not an at-home device. The plasma pen is for confirmed benign, stable, identified spots only.

Treating vs waiting: a realistic side by side

Treating now (plasma pen) Waiting
The treated spot Gone in 7 to 21 days. That specific lesion does not come back. Still there. May stay the same or grow slightly over time.
New spots forming Unaffected. Same underlying causes continue. Unaffected. Same underlying causes continue.
Time investment 5 minutes per spot, one treatment session. Ongoing monitoring for any changes; a derm visit if something changes.
Safety Requires correct identification first. Safe for confirmed benign spots. Always safe for genuinely benign, stable spots.
Day-to-day awareness Decision made. Resolution visible by Week 2 to 3. Spot stays in your peripheral awareness each time you see it.

Neither column is inherently wrong. The choice belongs to you. The table gives you the honest read on what each path actually means.

What treating now actually looks like

The five-minute treatment

One five-minute treatment per spot with the OcuraLife Plasma Pen. The pen's precision tip delivers plasma energy directly to the lesion, targeting and carbonizing the spot at the cellular level without affecting the surrounding skin. No clinic visit, no appointment, no referral needed.

The healing window

A small protective scab forms over the treated spot. It falls off naturally between Day 3 and Day 7. Do not pick at it. By Week 2 to 3, clear skin is visible where the spot was. The pen has 9 power settings, so the intensity matches the size and type of each spot. Full details on what to expect at each stage of recovery are at plasma pen healing stages.

FAQ

Frequently asked questions

Common questions from people weighing whether to treat now or wait.

The questions people ask before deciding

Tap each question to reveal the answer.

Will a cherry angioma get bigger if I leave it alone?

Most cherry angiomas remain stable in size once they form. They are benign vascular overgrowths with no malignant potential. What does change over time for many people: more cherry angiomas tend to appear with age, so you may go from one or two to several over a decade. The individual spot is unlikely to grow dramatically, but the overall count often increases without treatment.

Can skin spots spread to other people or other parts of the body?

Benign skin spots like cherry angiomas, skin tags, milia, and sebaceous hyperplasia are not contagious and cannot spread from one person to another. They also do not spread across the body in the way an infection would. New spots of the same type may appear elsewhere over time because the underlying skin and hormonal conditions that cause them continue, but each spot forms independently.

Is it dangerous to leave a benign spot untreated for years?

No, leaving a confirmed benign spot untreated is not medically dangerous. Cherry angiomas, skin tags, milia, and sebaceous hyperplasia are all benign and do not become cancerous on their own. The only scenario where leaving a spot becomes a concern is if you are not certain it is benign, or if it begins to change over time. In either case, a dermatologist should evaluate it. A stable, identified benign spot is safe to leave indefinitely.

What makes a spot stable versus one that might need medical attention?

A stable spot has looked the same for at least several months: same size, same color, same shape, no bleeding, no itching. A spot that warrants medical attention is one that has changed in any of those dimensions over weeks to months, bleeds on its own, has visible blood vessels on the surface, or looks pearly or translucent rather than matte. If a spot meets any of those criteria, see a dermatologist before considering at-home treatment.

How do I know if a spot is safe to treat at home with a plasma pen?

A spot is a candidate for at-home plasma pen treatment when it is confirmed benign, located somewhere you can see and access clearly, not showing any red-flag signs (bleeding, visible blood vessels, pearly appearance, rapid change), and you have reviewed the device safety guidelines. The OcuraLife Plasma Pen is designed for confirmed benign blemishes including cherry angiomas, skin tags, milia, and sebaceous hyperplasia. It is not for use on moles or any spot that has not been clearly identified as benign. See is the plasma pen safe? for the complete safety guide.

The bottom line

Most benign spots will not get worse in any medically serious sense if you leave them alone. Some will multiply over time. Some may grow very slightly. Cherry angiomas, skin tags, milia, and sebaceous hyperplasia are all safe to leave if they are stable and identified. The choice to treat now is a comfort and clarity decision, not a medical emergency.

When you are ready to treat, the at-home option built for this is the OcuraLife Plasma Pen: five minutes per spot, results visible by Week 2 to 3, no clinic appointment needed. For the full picture on how it works and what to expect, see Does the Plasma Pen Actually Work?
