LA ROCHE-POSAY, a leading dermo-cosmetic brand from L'Oréal Group's Japanese subsidiary, Nihon L'Oréal K.K. (Shinjuku-ku, Tokyo), has designated April 30th as 'No Spot (4.30) Day.'
In conjunction with this, the official online shop is hosting a limited-time 'Shimi Zero WEEK' campaign. This year, the brand welcomes Sumisho, a cosmetics researcher and YouTuber widely trusted for his expert analysis, to present special content on a dedicated page titled 'The Truth of UV Rays' and 'How to Choose Sunscreens that Shape Your Future Skin.'
