Recognizing these limitations, the dermatology community now emphasizes strategies rooted in deep mechanistic understanding:

• Biologics targeting specific cytokines like IL-4, IL-13, IL-17 facilitate immune modulation rather than broad immunosuppression.
• Regenerative therapies, including exosomes, stem cell treatments, and bioengineered skin constructs, aim to repair tissue damage and restore normal skin architecture.
• Digital diagnostics, AI-powered assessment tools, and wearable sensors enable early detection, real-time monitoring, and dynamic treatment adjustments.

This holistic, personalized approach emphasizes preventive care, long-term skin resilience, and patient empowerment, ultimately shifting the focus from symptoms to disease modification.
