A plasma pen procedure has three phases: prep, a 5-minute active treatment per blemish, and a healing period where a small scab forms and falls away on its own by Day 3 to 7. Clear skin is visible by Week 2 to 3. The steps below walk you through exactly what to do before you pick up the pen, during treatment, and through the full healing window, so you know what to expect at every stage.
If you want to understand how a plasma pen actually works at the tissue level before reading the procedure, that guide covers the mechanism in full. This article is the step-by-step walkthrough.
Key takeaways
Three phases, predictable timeline: prep your skin, treat the blemish in about 5 minutes, then let the scab form and fall away naturally over the next 3 to 7 days.
- Clean and dry skin responds most predictably to the plasma arc. Numbing cream is optional but removes discomfort.
- Start at a conservative power setting. You can always increase intensity on a second pass. You cannot undo.
- The scab is doing its job. Do not pick at it. Picking is the most common cause of prolonged marks.
- New skin is sun-sensitive. Daily SPF 50 from Day 3 through Week 3 protects the result.
- If a spot is changing, bleeding, or shaped irregularly, it is not suitable for at-home treatment. See a dermatologist first.
What happens during a plasma pen procedure
A plasma pen works by delivering a controlled arc of ionized plasma to a blemish. The plasma energy heats and cauterizes the target tissue without touching the surrounding skin. The precision tip is the tool. The power setting determines how much energy reaches the spot. The OcuraLife Plasma Pen has 9 intensity settings so you can match the treatment to the size and depth of the blemish, from a fine skin tag to a more resistant age spot or fibroblast treatment application.
The "5 minutes per blemish" figure is the active treatment time, not the full session time. If you are using numbing cream and treating multiple spots, the session will be longer. Each individual blemish, from first contact to lifting the pen, takes a few minutes at most.
What the plasma arc does to your skin
The ionized plasma arc forms between the pen tip and the skin surface without the tip physically touching the tissue. This micro-arc heats the blemish tissue to cauterize it. Healthy skin immediately around the spot is not affected. The body then begins a natural healing response: a small scab forms over the treated area, the skin regenerates underneath it, and the scab lifts on its own once the new skin is ready. The process is the same mechanism used in clinical electrocautery and laser procedures, adapted for consumer-grade home use. Conditions the pen works on include skin tags, milia, cherry angiomas, age spots, and sebaceous hyperplasia, all of which sit in the upper layers of skin where the plasma arc can reach them effectively.
Step-by-step: prep, treatment, and aftercare
The sequence below follows the three-phase structure of every plasma pen procedure. Follow it in order.
Step 1: Prep your skin
Clean the area you plan to treat with a gentle, fragrance-free cleanser. Rinse thoroughly and let the skin dry completely. Dry skin responds more predictably to the plasma arc than skin with any moisture, cream, or residue on the surface. If you plan to use numbing cream, apply it now and allow the full time the cream's instructions specify, typically 20 to 30 minutes. Do not rush the numbing window. The cream will make the procedure more comfortable and does not affect the result.
Step 2: Choose your power setting
The OcuraLife Plasma Pen has 9 intensity settings. For your first treatment on any area, start at the conservative end of the range. Smaller, shallower blemishes (small skin tag, milia, superficial age spot) need less intensity than larger or thicker spots. If you are treating a blemish for the first time and are not sure of the right setting, err lower. You can always increase the setting on a follow-up pass after you see how the skin responded. You cannot reverse an overly aggressive first treatment.
Step 3: Treat the blemish
Hold the pen tip approximately 1 to 2 mm from the skin surface above the blemish. Apply brief, precise contact to the target spot. Each individual application takes a few seconds. The active treatment for one blemish is typically around 5 minutes total. Work with controlled, deliberate movements. The goal is consistent cauterization of the target tissue, not pressure or speed. Do not press harder or hold longer to force a faster result. The plasma arc does the work at the cellular level. Your job is positioning and precision.
Step 4: Move directly to aftercare
The moment treatment on a spot is complete, the healing phase begins. Do not apply makeup, heavy cream, or any occlusive product to the treated area on the day of treatment. If you are treating multiple spots in the same session, move through each one before starting aftercare. Do not treat spots you are uncertain about. If a spot does not clearly match the profile of a benign blemish you have identified with confidence, stop and see a dermatologist before proceeding.
Aftercare and the healing timeline
The treated area will form a small, dry scab. The scab is the body's natural protective covering while the skin regenerates underneath. Keep it clean and dry. Do not pick at it under any circumstances. Picking is the single most common cause of prolonged healing and post-treatment marks that outlast the blemish itself.
Day 1
Treat and scab forms
A few minutes per blemish. A small protective scab forms the same day. Healing patches protect friction points like glasses or hairline.
Day 3-7
Scab releases naturally
Do not pick. Once the scab is gone, recovery cream supports the fresh skin underneath.
Week 2-3
Skin renewed and clear
New skin burns easily. Apply SPF 50 every morning while the area finishes settling.
If you are treating several spots, spread treatments across sessions rather than all in one go. Watching how your skin responds to the first spot before treating more keeps the aftercare manageable and gives you real feedback on your settings.
The scab is not the problem. Picking the scab is.
How plasma pen compares to clinic options
The at-home plasma pen procedure and clinical skin treatments use the same underlying principle: controlled energy delivery to cauterize or destroy blemish tissue. What changes is the setting and the operator. Understanding what each option actually does helps you decide when at-home treatment is appropriate and when a clinic is the right call.
Electrocautery and laser
Electrocautery and CO2 laser treatments at a dermatology office deliver higher-intensity energy than a consumer plasma pen. They are appropriate for larger, deeper, or more complex lesions and require a trained professional to operate safely. For benign surface blemishes that fit the profile of skin tags, milia, or minor age spots, the mechanism is comparable. The clinic difference is scale and control, not a different biological process. If you are considering a clinic because a blemish is larger than typical or you are unsure of its nature, that is exactly the right call.
Cryotherapy
Cryotherapy for skin tags uses extreme cold rather than heat to destroy the blemish tissue. Both approaches are effective for suitable lesions. Cryotherapy tends to require multiple sessions for full removal and can leave a pale mark at the treatment site. The plasma pen typically resolves a benign blemish in one session with a predictable scab-and-clear cycle. Neither is universally better; both are legitimate mechanisms for benign tissue removal.

How to stay safe: realistic expectations
At-home plasma pen treatment is appropriate for confirmed benign blemishes that fit the profile of the conditions the device is designed for: skin tags, milia, cherry angiomas, age spots, sebaceous hyperplasia, and similar surface lesions. Realistic expectations matter. The procedure involves mild discomfort, a healing scab, and a two to three week clear-up window. It is not painless. It is not instant. And it does not work on every type of skin lesion.
See a dermatologist instead if
- The spot is changing in size, shape, or color.
- The spot bleeds without trauma, or is painful to touch.
- The border is irregular, or the spot does not match the expected profile of a benign blemish.
- You are not confident in what the spot is.
- The lesion is deep, raised beyond a few millimeters, or has returned after previous treatment.
Per the American Academy of Dermatology, any skin growth that is changing in appearance or behavior should be evaluated in person before at-home treatment is attempted. The Mayo Clinic similarly emphasizes professional evaluation for lesions that are new, rapidly changing, or of uncertain type. The NIH MedlinePlus skin conditions reference is a useful general starting point for understanding what different skin conditions look like. None of these sources substitute for an in-person examination when there is any doubt.

The bottom line
A plasma pen procedure follows a predictable three-phase structure: prep your skin and apply numbing cream if you want it, deliver the treatment to each blemish in about 5 minutes per spot, then let the healing cycle run its course. A scab forms, falls away on its own by Day 3 to 7, and clear skin is visible by Week 2 to 3. Start at a conservative power setting. Do not pick the scab. Protect the treated area with daily SPF 50 through Week 3. If a spot is changing, bleeding, or uncertain, see a dermatologist before treating at home.
