Manufacturing process

~Utilizing the blessings of nature in their natural form~

We maximize the natural nutrients and active ingredients of the egg, from the yolk to the white, the shell, and even the beauty-enhancing shell membrane.

Products undergo rigid testing!


Softshell turtle eggs (and other foods imported to Japan from overseas) must undergo a very stringent testing process. This ensures that only perfectly safe and high-quality eggs are used to make Remain Young.

The ingredients that go into Remain Young have been verified safe through analyses of sampled eggs conducted prior to import.
