It seems that the search results provided are not relevant to the question about "whitening blemish" and whether it is registered with BPOM (Badan Pengawas Obat dan Makanan, the Indonesian Food and Drug Authority). As a result, Im unable to provide specific product details, positive or negative aspects, or the ingredients or materials of the product. If you have a specific product in mind, I recommend checking the official BPOM website or contacting the manufacturer for accurate and reliable information.
