The main point is about goals. The authors say the aim is moving from fixing visible signs to protecting skin health over the long run. They credit four areas of science:
-
Epigenetics, how your genes switch on and off over a lifetime.
-
Microbiome science, the study of the tiny living things on your skin and in your body.
-
Nerve and skin biology, how your nerves and skin are linked.
-
Artificial intelligence and other digital tools.
Together, these fields support a view of skin as a living organ that adapts. Treatments should still improve how skin looks. But they should also help skin cells stay resilient, help control inflammation and support the skin's own renewal over time.
The review also wants care to be personal, predictive and proactive: fitted to you, looking ahead and acting early.
