• Application Method: According to the manufacturer guidelines on the box, a suitable amount should be applied evenly to a cleansed face and gently massaged until fully absorbed. 
• Safety Guidelines: The packaging explicitly advises conducting a patch test behind the ear before using a new cosmetic product to check for any adverse or allergic reactions. It warns against use on damaged or broken skin.
