[Pores & Scars] Atrophic Scars and Enlarged Pores: Pico Fractional vs. Potenza — Which Is Right for You?
Hello. I'm Dr. Jung Huh, Chief Director of Ruby Dermatology Clinic, where we help restore your skin's natural, healthy vitality and smoothness.
"My pores keep getting bigger and I'm bothered by the pitted acne scars I've had since I was young. Should I get Pico Fractional or Potenza?"
The question I chose as the topic of this final, 20th Doctor's Note is one of the hottest topics in the clinic: 'comparing combined solutions for pores and scars.'
Pico Fractional and Potenza are both excellent devices for treating pores and pitted scars, but the 'mechanism by which they deliver energy to the skin (light vs. needle radiofrequency)' is completely different. Treatment satisfaction is maximized when the right choice is made based on your scar type, pore depth, and desired recovery time (downtime).
💡 [3-Line Key Summary]
Difference in mechanism: Pico Fractional uses ultra-short laser shock waves (LIOB) to create microscopic cavities in the dermis without damaging the epidermis, regenerating collagen, while Potenza delivers radiofrequency (RF) thermal energy through microneedles that penetrate the skin directly.
Recommendations by scar and pore type: 'Pico Fractional' suits scars with relatively well-defined borders and texture improvement, while 'Potenza' is useful for oily skin with excess sebum, deep pores in the butterfly zone (central cheeks and nose), or accompanying redness.
Synergy combination: Alternating or combining the Potenza CP-25 pumping tip, which has high drug-penetration efficiency, with Pico Fractional by skin layer doubles the recovery speed of pitted scars.
A. Pico Fractional vs. Potenza: Fundamental Differences in How They Work
Both procedures work by creating tiny wounds (coagulation points) in the dermis to regenerate collagen through the skin's self-healing response, but their approaches are completely different.
Pico Fractional (Pico Fractional Laser — LIOB mechanism):
Principle: A picosecond (one trillionth of a second) laser beam is split by an MLA (Micro Lens Array) tip, inducing LIOB (Laser-Induced Optical Breakdown) within the dermis without damaging the skin surface.
Features: By creating extremely tiny cavities (bubbles) within the dermis without peeling the epidermis, it triggers powerful collagen remodeling without surface wounds or scabs.
Potenza (Potenza Microneedle RF):
Principle: Sterile microneedles penetrate the epidermis directly and then emit radiofrequency (RF) thermal energy from the needle tips.
Features: It simultaneously induces sebaceous gland shrinkage and collagen contraction in the dermis, and with a negative-pressure pumping tip, skin booster agents such as Juvelook can be delivered deep into the dermis without loss.

B. Is It Right for Me? Choosing by Skin Concern
1) When Pico Fractional is recommended
You want to soften the borders of pitted acne scars (ice-pick and round types)
You want to smooth out fine surface irregularities and rough skin texture at the same time
You found traditional fractional procedures, with their lingering redness and scabs, burdensome
2) When Potenza is recommended
You are bothered by both enlarged pores, mainly in the butterfly zone, and shiny oil production
You want to fill in depressed areas by infusing collagen skin booster agents such as Juvelook Skin into the dermis in quantity
You want combined care for skin redness or loss of elasticity along with pores and scars
C. Pico Fractional vs. Potenza: A Complete Comparison at a Glance
| Category | Pico Fractional | Potenza RF |
|---|---|---|
| Energy principle | Picosecond laser shock wave (LIOB) | Microneedle + radiofrequency (RF) |
| Main target layer | Upper and mid dermis (LIOB micro-spaces) | Mid and lower dermis (RF thermal coagulation points) |
| Main indications | Pitted acne scars, surface irregularities, texture improvement | Enlarged pores, sebum control, skin booster penetration |
| Downtime | 1–3 days of mild redness (almost no scabbing) | 1–2 days of mild redness and tiny needle marks |
| Drug penetration | Absorption through topical application after the procedure | Direct penetration via negative-pressure pumping tip (CP-25) |
D. Differences in Recovery (Downtime) and Pain
Pain:
Pico Fractional: With numbing cream applied, you feel only a prickling photoacoustic stimulation, so it is relatively easy to tolerate.
Potenza: You feel a heavy sensation of the needles penetrating the dermis along with RF heat, but with sufficient anesthesia you can undergo the procedure comfortably.
Downtime:
Pico Fractional: Redness and tiny pinpoint bleeding may appear right after the procedure, but they subside within 1–3 days and no surface scabs form, so you can return to daily life quickly.
Potenza: Slight redness and embossing appear on the day of the procedure, and you can wash your face and wear light makeup the next day.

E. Recommended Treatment Interval and Plan
Pico Fractional: At 3–4 week intervals, 3–5 or more sessions allow dermal collagen to build up and the borders of pitted scars to soften.
Potenza: At 3–4 week intervals, 3–5 sessions are recommended, and when combined with Juvelook, the pore-tightening effect accumulates progressively.
F. 🔥 The Best Synergy Combinations for Finishing Off Pitted Scars and Pores
Potenza (CP-25) + Juvelook Skin:
The negative pressure created by Potenza's pumping tip pushes Juvelook into the dermis, powerfully stimulating the body's own collagen production from the very base of pitted scars.
Pico Fractional + Potenza Dual-Layering Care:
A combination solution in which Potenza refines the lower dermis for deep, wide pores and sebaceous glands, while Pico Fractional's LIOB mechanism treats surface pitted scars and texture.
G. Dr. Huh's Practical Know-How & Clinical Insights
As I have always emphasized throughout these 20 Doctor's Notes, the essence of every skin procedure is 'customized design based on accurate diagnosis.'
For pores and scars as well, a precise diagnostic system must clearly distinguish the scar type (ice-pick, boxcar, round) and the origin of the pores (excess sebum type vs. reduced elasticity type). For acne scars with deep surface irregularities, I finely adjust Pico Fractional's LIOB energy to break up fibrotic scar bands, and when enlarged pores come with dehydration, I precisely infuse Juvelook into the dermis using Potenza's CP-25 tip. By using these two mechanisms in harmony, you can build a smooth skin foundation that fills in from within, without burdening the skin with irritation.
📌 [Wrap-Up] Pre- and Post-Treatment Precautions
Plenty of hydration and regeneration care: Dermal collagen remodeling is very active after the procedure, so apply regenerating cream and moisturizer thoroughly and often.
Sun protection: UV rays interfere with the formation of regenerating dermal collagen, so apply sunscreen of SPF 50+/PA+++ or higher every day.
Avoid irritation: For one week after the procedure, avoid saunas, jjimjilbang (Korean bathhouses), strenuous exercise, and alcohol-containing toners or scrubs.
