A general rule is to apply products from thinnest to thickest texture. A typical morning routine: gentle cleanse, water-based serum (if used), moisturiser, then sun protection. In the evening, replace sun protection with a nourishing overnight care.
Just as important: don't overcomplicate. Multi-step routines with many actives can tire sensitive skin. A "less but right" approach is more sustainable. EVİA offers personalised protocol support for clinicians.
