Recovery and Pigment Safety in the 2026 Split-Face Acne Scar Trial: What the Trial Means for People With Skin of Color

The 2026 split-face trial points to brief recovery and low, short-lived pigment risk for skin of color. For readers with Fitzpatrick types III–V and indented acne scars, treated skin improved more with no lasting pigment harm reported.

A split-face trial treats one side of the face and compares it with the other side. This trial enrolled Asian adults with moderate-to-severe atrophic scars, meaning indented scars. It compared fractional microneedle radiofrequency plus transdermal poly-L-lactic acid against control over six months, as reported by Dermatology and Therapy.

Who was studied and what improved?

Participants had Fitzpatrick types III–V, skin that tans easily and can darken after injury. All had moderate-to-severe indented scars.

Dermatology and Therapy reports greater gains in texture and scar volume at six months on sides treated with poly-L-lactic acid. More participants reported at least 75% improvement on the treated side. That outcome reflects visible texture change, not complete scar removal.

How long did recovery take?

Recovery was brief for most participants. After the first treatment, one participant (4.2%) had mild redness that cleared within one month, as detailed in the study report.

Another participant (4.2%) had an acne flare that cleared within five days. The same report notes a similarly brief, transient pattern after the second treatment. That short course helps with planning work, school, or events.

Did dark spots appear?

Mild postinflammatory darkening, meaning dark spots after inflammation, occurred in two participants (8.3%) and cleared within one month, according to the safety results. The report lists no infections, raised thick scars, or serious adverse events.

Baseline risk remains higher for skin of color. Dermatology Times notes prior literature citing up to 90% of darker Fitzpatrick types developing dark spots after acne, plus keloid and melanocyte-reactivity risks, in its trial coverage.

What limits and device risks matter?

This was a focused group: Asian adults with Fitzpatrick types III–V, followed for six months. Results may not predict outcomes for other tones, scar types, or longer periods. A separate 47-person laser study across Fitzpatrick types I–VI also reported scar improvement.

Serious device harm remains possible with radiofrequency microneedling. Global Cosmetics News, reporting an FDA safety communication from Oct. 15, 2025, warns of burns, scarring, fat loss, disfigurement and nerve damage sometimes needing medical or surgical repair in its safety report.

What should you do before booking?

Daily habits affect pigment risk. The American Academy of Dermatology advises against picking, popping or squeezing acne because it delays clearing and raises scarring and dark-spot risk. It also advises avoiding tanning, seeking shade, and protecting sun-sensitive skin.

Use a dermatology visit to match the trial to your skin and history. Ask about experience with your Fitzpatrick type, pigment prevention, device settings, and aftercare. Bring a list of past dark spots, keloids, and tanning habits to that visit.
