Product placement
(a) Medicube Smooth and Clear: The product is shown being applied to skin, and its ingredients (Niacinamide, Alpha-arbutin, Kojic Acid) are listed as the reason for the visible skin brightening results. It acts as the primary solution for the skin issues shown. (b) TeaShell: The packaging is shown at the end with the product name and ingredients, acting as the final reveal of the product being used. Removing these would change the video as the specific solution would be unknown.
