5. TRANSINO Whitening Tablets Premium: 1-Month Trial Review

Every year from June to September, the sun is so fierce it feels like it's going to bite. The correspondent, who is used to only using an umbrella for shade, always fails to escape the fate of getting tanned or even sunburned, and it takes the whole winter to naturally whiten back. This year, I'm going to try eating for 30 days TRANSINO Whitening Tablets Premium...Let's see if skin-whitening through "diet" is actually more effective than skin-whitening through "topical application."
6. First experience with TRANSINO Whitening Tablets Premium! No side effects so far.

At first glance, TRANSINO Whitening Tablets look snow-white, but upon closer inspection, they have a very, very pale pink tint. They are circular with a diameter of about 0.5 cm and a thickness of about 0.2 cm. Being a medium-small size, most adults can swallow 3 tablets directly with water. The special correspondent took them once in the morning upon waking up and once before going to bed at night, and did not experience any side effects after finishing the first day.
7. TRANSINO Whitening Tablets Premium 2-Week Follow-up

Left image: 7 days after taking whitening pills, Right image: 14 days after taking whitening pills
For the first 2 weeks of taking whitening pills, my body didn't feel any abnormalities, and I haven't noticed any whitening or brightening effects on my skin yet. This is probably because 2 weeks is still less than the skin's roughly 28-day turnover cycle, so the period of use and observation needs to be extended. Meanwhile, the previous sunburn still leaves a noticeable color difference.
8. Menstrual changes after taking TRANSINO White C Premium

My period came right on the 25th day of taking them, which was 4 days longer than my last cycle, but since the correspondent's menstrual cycle is naturally very irregular, it's hard to conclude that the delay was caused by taking the whitening pills.

Surprisingly, the menstrual flow was noticeably lighter than before. Normally, it lasts the full 7 days, but after taking the whitening pills for about 3 weeks, I didn't need to use any protection after the 4th day. This might be related to how "high-dose Vitamin C" can help with blood clotting functions. Incidentally, the menstrual cramps still lasted the full 3 days, completely unaffected by the whitening pills.
9. TRANSINO Whitening Tablets Premium 1-Month Follow-up

Left: 21 days after taking whitening pills, Right: 28 days after taking whitening pills
After finishing a 30-day supply of whitening pills and comparing the results to a photo taken right after getting a sunburn, I noticed that the tan lines have faded significantly. And compared to previous summers when going out just a few times would immediately darken my skin by several shades, this year, after starting the whitening pills, even though I went out to walk the kids more often than in the past (unable to use an umbrella for shade), the overall degree of skin darkening was much less. Even my family member, the Special Correspondent, said, "You're the only one in the whole family who doesn't seem to have gotten tanned at all!"
10. Hands-On Review of TRANSINO Whitening Tablets Premium: Whitening Effects & Side Effects Comprehensive Evaluation

Compared to before, the tan lines have become blurred and the overall skin tone has also brightened.
Taken this time TRANSINO Whitening TabletsConducting a real-world test, I took a full 30-day supply starting in mid-July. Now, nearly 2 months have passed as of writing this article, and the whitening effects I experienced mainly manifested in two aspects: "resistance to tanning" and "accelerated brightening recovery."
Ultimately, I’m satisfied with the results I’ve seen from Daiichi Sankyo’s TRANSINO, and I’ll continue to keep an eye on this product in the future.

Changes during the menstrual period are also one of the whitening pill side effects that the correspondent cares quite a bit about. Although, aside from longer intervals between cycles and a lighter menstrual flow, there were no other discomfort symptoms or bleeding outside of the menstrual period, just to be safe, it was decided not to continue taking them after finishing the 30-day supply.

Recently, many major Japanese food and supplement companies have also been successively launching high-dose vitamin C tablets or similar skin-whitening drinks. I will have a chance to share the physical changes I experienced after taking them with you all!
