Field Notes

JAK inhibitors specifically interfere with pro-inflammatory signaling cascades—and thus also change what accompanying skincare must achieve. What research on the JAK-STAT axis and barrier regeneration...

So-called chrono-peptides synchronize topical active ingredients with the skin's circadian rhythms. What research says about how time-controlled release systems work and what this means for...

Senescent cells accumulate in the skin with increasing age and release inflammatory signaling molecules. What senolytics research teaches us about this — and what it...

While we sleep, our skin regenerates at full speed. Why overnight masks are more than just a hydration trend — and how chronobiology, occlusion, and...

Red and near-infrared light can modulate cellular processes in the skin—from mitochondrial energy production to fibroblast activation. What research on photobiomodulation shows and how red...

Luxury and sustainability were long considered a contradiction. Refill ecosystems show how high-quality cosmetic formulas, circular packaging concepts, and genuine ecological impact can converge.

Today, the connection between stress and skin is scientifically well-established: cortisol weakens the barrier function, neurogenic inflammation activates mast cells, and chronic stress accelerates inflammaging.

Skin quality is often reduced to the right serum. But research shows that environmental influences, sleep, biological rhythms, and targeted care work together as a...

Skincare is usually discussed in terms of the right active ingredients – but a crucial variable is often overlooked: timing. Chronobiology shows that the skin...
