After your morning toner or serum, dispense a generous, even layer onto the face and neck as the final step of your skincare routine, at least 15 minutes before sun exposure. Gently pat and smooth until fully absorbed. Reapply every 2‑3 hours when outdoors, especially after sweating, swimming, or towel‑drying. Can be worn alone as a combined serum and sunscreen, or layered over other non‑oil‑based treatments. Use daily.
