■ About the TV Commercial
Mouth ulcers are common among men and women in their 20s and 30s. Many people cite "fatigue" and "stress" as causes of mouth ulcers, and the need for daily treatment of mouth ulcers is increasing. Against this backdrop, Daiichi Sankyo Healthcare, based on the knowledge cultivated through its "Traful®" series of over-the-counter mouth ulcer medications, produced new TV commercials to convey the existence of "Traful® BB Charge c," a vitamin supplement* effective for mouth ulcers caused by fatigue and stress. Continuing to cast Kotomi Tachibana of "CANDY TUNE" as the image character from the "Traful® Direct a" commercial, the new commercials deliver the message, "Traful® BB Charge c is a vitamin supplement* effective for mouth ulcers caused by lack of sleep and fatigue," by portraying her tenderly caring for existing mouth ulcers and taking Traful instead of leaving them untreated.
■ TV Commercial Story
◆ Traful® BB Charge c "Kōnai E-n" commercial
Kotomi Tachibana appears with a puppet "Ko-Kot-chan" dressed in matching outfits. "Ko-Kot-chan" rhythmically sings the phrase, "Got one! Kōnai E-n!" and surprisingly, there's a painful-looking mouth ulcer inside "Ko-Kot-chan's" mouth! Tachibana-san worries about "Ko-Kot-chan's" distressed expression. Afterwards, she energetically sings the same phrase again. Finally, Tachibana-san and "Ko-Kot-chan" smile brightly, cutely conveying the message, "A vitamin supplement* effective for mouth ulcers," through song and dance.
*Vitamin B2B6 main ingredient formulation
◆ Traful® BB Charge c "Hakken! Kōnai En" commercial
In this commercial, Tachibana-san plays a busy designer. As she works from morning till night, an arrow indicating "lack of sleep mouth ulcer" appears near her mouth. The next day, as she slumps, saying "I'm tired~", an arrow indicating "fatigue mouth ulcer" appears. Asked, "Leave it? Or Traful it?", she charges up with vitamins from "Traful® BB Charge c" and falls asleep with a smile. On a different day at noon, Tachibana-san enjoys a meal deliciously, her mouth ulcer having healed. Through Tachibana-san's relatable portrayal, the commercial expresses that "Traful® BB Charge c" is effective for mouth ulcers caused by lack of sleep and fatigue.
