Cleanse: Start with a clean, dry face.
Apply: Use the dropper to apply 1–2 pumps (or a few drops) to the face and neck.
Target: You can apply it to the whole face for general brightening or focus specifically on areas of darkening.
Timing: * If this is the Day Serum, apply in the morning and always follow with SPF.
If it is a Night Serum (containing Hydroquinone or Tretinoin), apply only in the evening.
Frequency: If you are a new user, start by applying on alternate nights for the first week to ensure your skin tolerates the active ingredients before moving to daily use.
