A split-face trial tests skincare alongside picosecond laser treatment
Thirty-five participants received the same laser sessions while each side of the face followed a different topical regimen. The paper reports useful measurements alongside commercial affiliations that readers should see.

Why it matters
Procedure outcomes depend partly on recovery and barrier support, an area often discussed with more confidence than comparative evidence supports.
What we don't know
The study was small and tested a branded product bundle, so it cannot isolate one ingredient. Two authors list L'Oréal Taiwan affiliations, while the paper declares no related conflict of interest.
What was compared
Thirty-five adults with facial photoaging underwent three 755-nm picosecond alexandrite laser sessions. One cheek received a control recovery regimen; the other added a branded antioxidant, tranexamic-acid, and lipid-restoring routine.
How to read it
A split-face design reduces some person-to-person variation, but a bundle of several products makes the active contribution hard to isolate. A single-center result also needs replication across more skin tones, settings, and devices.
Laser treatment is a medical decision. Product layering after a procedure should follow the treating clinician’s instructions, not a generalized routine copied from a study abstract.
