A 112-day randomized controlled trial found that a combination cream and serum containing niacinamide, Pro-Xylane, and panthenol accelerated skin barrier repair in the first two weeks after PicoWay laser treatment and produced measurable improvements in skin elasticity, firmness, and wrinkle appearance over the full study period compared to standard care .
Researchers recruited 88 Chinese women undergoing PicoWay laser treatment, a procedure that uses picosecond laser pulses to address skin texture, tone, and aging signs. The study split participants into two groups: one using REGENMEDIC cream and serum (a proprietary formulation) alongside laser treatment, and another using standard post-procedure care with a basic moisturizer. The design allowed researchers to isolate whether the multi-ingredient regimen provided benefits beyond conventional recovery protocols.
The early phase of recovery proved critical. During the first 14 days after laser treatment, the test group using REGENMEDIC products showed measurably lower transepidermal water loss (TEWL), a standard marker of skin barrier function. TEWL is the amount of water that evaporates through the skin, so lower values indicate a more intact barrier. The test group also demonstrated higher skin hydration levels and faster reduction in post-procedure redness compared to controls. These findings suggest the cream's combination of ingredients acted to restore the damaged barrier that laser treatment inevitably creates. Niacinamide, the study notes, supports barrier lipid production, while panthenol (provitamin B5) enhances skin hydration and has mild anti-inflammatory properties. Pro-Xylane, a xylose-derived compound, is included specifically for its purported effects on skin matrix support, though clinical evidence for this ingredient remains limited.
The longer-term outcomes measured over 112 days showed sustained benefits. Participants using the full regimen exhibited increased skin elasticity and firmness compared to the control group, with dermatologists documenting reduced wrinkle depth and improvements in overall skin tone and texture. The control group did improve over time (laser treatment itself drives collagen remodeling), but the test group's gains were larger. Notably, the study found excellent tolerability across both groups with minimal adverse events, suggesting the regimen did not compromise safety.
A key claim the researchers make is that targeting "multiple physiological pathways" simultaneously produces synergistic effects. The logic is sound: rapid barrier repair in early recovery may create conditions that amplify the skin's response to subsequent anti-aging ingredients over weeks and months. However, the study does not isolate which ingredient or ingredient pairing drove which outcome. We cannot tell from this design whether all three key ingredients (niacinamide, Pro-Xylane, panthenol) were necessary, or whether one or two were responsible for most benefits.
If you are planning or have recently undergone laser resurfacing, this study provides evidence that targeted post-procedure skincare formulations can accelerate barrier recovery and enhance aesthetic outcomes. The early emphasis on hydration and barrier repair aligns with dermatological consensus: the first two weeks matter most for preventing complications and setting up the skin for optimal remodeling.
The specific ingredients tested here have varying levels of supporting evidence. Niacinamide (vitamin B3) has robust clinical evidence for barrier support and inflammatory reduction. Panthenol has long been used in dermatology for similar purposes. Pro-Xylane is newer and less well-studied; its inclusion here is based on mechanistic reasoning rather than extensive human trials. If you are considering a regimen, the presence of niacinamide and panthenol in a post-laser moisturizer is likely valuable, though you need not purchase the exact brand tested to access those benefits.
This study was conducted in a specific population (Chinese women) following a specific laser type (PicoWay). Results may not generalize equally to other skin types, ethnic backgrounds, laser platforms, or skin conditions. Additionally, this research was conducted in a clinical trial setting with structured product application and follow-up, which differs from real-world use patterns.
The practical takeaway: systematic, multi-step skincare immediately after laser treatment appears to outperform minimal intervention. Focus on barrier repair first, anti-aging benefits second, and plan for consistency over at least 112 days to see the full magnitude of effect.

Study examined a proprietary formulation combining niacinamide, Pro-Xylane, and panthenol. The individual ingredients have separate bodies of evidence: niacinamide is established for barrier support; panthenol for hydration and soothing; Pro-Xylane is investigational for skin matrix effects. The synergy claim is plausible but unproven from this single trial design.
