What it is
A scar forms when inflammation reaches deep enough to destroy collagen in the dermis, and healing fills the gap unevenly. Under-filling leaves atrophic scars in three shapes: icepick (narrow pits under 2 mm wide, deep and V-shaped), boxcar (wider depressions with sharp vertical edges), and rolling (broad waves tethered down by fibrous bands under the skin). Over-filling builds raised hypertrophic scars, more common on the jaw, chest and back.
Flat red or brown marks are a different thing: post-inflammatory erythema and hyperpigmentation, leftover vessels and melanin rather than missing tissue. They fade over weeks to months and respond to pigment topicals and vascular lasers. True scars need remodeling. RF microneedling passes insulated needles into the dermis and fires radiofrequency heat at the tips, triggering new collagen while the surface stays mostly untouched. Fractional lasers vaporize microscopic columns of tissue toward the same end.
The numbers: in a split-face randomized trial, 3 sessions of RF microneedling cut scar scores 44 percent, statistically matching fractional CO2 at 42 percent, with shorter redness and fewer pigment problems. In a 397-patient cohort, 88 percent of fractional RF patients reached at least 25 percent improvement by month 6. The honest ceiling: no modality reliably exceeds 50 to 60 percent improvement in controlled data, and in one series about 1 in 6 patients saw no change. Smoother is realistic; gone is not.
What you may be noticing
- Shadowed pitting that shows in side lighting or on video calls
- Small deep pits on the cheeks, as if the skin was pierced
- Wider depressions with sharp, defined edges
- A rolling, uneven surface that smooths out when you stretch the skin
- Flat red or brown marks that slowly fade on their own (pigment, not scar)
- Foundation that settles into texture instead of covering it
How we approach it
- 1
Photos and intake online
You photograph your skin in good side lighting and complete the intake from your phone.
- 2
Phone consult
A call covers your history, skin tone, downtime tolerance and which approaches fit, before anything is booked.
- 3
Plan options in writing
You see RF microneedling and laser resurfacing compared side by side, with session counts and exact prices.
- 4
Exam, then same-day treatment
The in-person exam California requires before any energy device is folded into your first visit, and your first session follows immediately.
- 5
Sessions with photo tracking
Sessions run 3 to 8 weeks apart with standardized photos, because scar change is too slow to judge in a mirror.
The evidence
- Split-face randomized trial, 30 completers: RF microneedling cut ECCA scar scores 44 percent versus 42 percent for fractional CO2, with shorter erythema, pain and scab duration and fewer PIH events. Source →
- Propensity-matched cohort, 397 patients, Fitzpatrick III to IV: 88 percent of fractional RF patients reached at least 25 percent improvement at 6 months, versus 72 percent for fractional laser. Source →
- Prospective series, 40 completers, Fitzpatrick III to V: Goodman-Baron score fell 12.65 to 8.3 over 4 sessions; 7 of 40 saw no improvement. Source →
- 2024 systematic review, 16 studies: current evidence does not justify delaying energy-based devices during or after isotretinoin. Source →
Straight answers
- Are my marks scars or pigment?
- A useful home test: stretch the skin gently. A true atrophic scar keeps its shadow because tissue is missing; a flat mark that blends away when stretched is usually pigment or leftover vessels, which fade over months and respond to topicals or a vascular laser rather than remodeling. The in-person exam confirms which you have before any device fires.
- RF microneedling or laser resurfacing?
- A split-face randomized trial found no significant efficacy difference: 44 percent scar-score reduction for RF microneedling versus 42 percent for fractional CO2 over 3 sessions. RF microneedling had shorter redness, faster scab clearance and fewer pigment events; resurfacing can do more per session at the cost of roughly a week of visible recovery. Skin tone, scar shape and downtime tolerance decide it.
- How many sessions, and when do I see results?
- Published protocols cluster at 3 to 4 sessions, 3 to 8 weeks apart. Change builds slowly: in a 397-patient cohort, the share of patients with at least 25 percent improvement rose from 73 percent at month 1 to 88 percent at month 6. Judge at month 3, not week 2.
- Does it hurt?
- With numbing cream, published series report around 5 to 6 out of 10 at scar-depth settings, then 2 to 4 days of redness and swelling and flaking through about day 7. Worth knowing: the FDA's October 2025 safety communication on the RF microneedling device class reports burns, scarring, fat loss under the skin and nerve injury; a physician performing the exam and setting the parameters is the mitigation, and that is how this practice runs.
- I'm on isotretinoin. Do I have to wait?
- Usually not anymore. A 2024 systematic review of 16 studies concluded current evidence does not justify delaying energy-based treatment during or after isotretinoin, and the 2017 ASDS consensus reached the same for non-ablative devices. Fully ablative resurfacing still waits about 6 months. Dr. Mueller makes the call at your exam.
- What does it cost?
- RF microneedling is $425 a session or $1,140 for three. Mid-depth laser resurfacing is $850 and deep resurfacing is $1,400. Every number is itemized on the pricing page; nothing is added at checkout.
- Can scars be removed completely?
- No, and anyone claiming that is selling. Controlled data tops out around 50 to 60 percent improvement, which in practice means texture that reads smooth at conversation distance but is still findable up close. In one 40-patient series, about 1 in 6 saw no improvement; you hear that before you pay for a series.
