What is L – Cystine?

Do you want to have a complexion that shines like a white iridescent pearl? If so, 威信 ISHIN Premium is the supplement for you!

What makes 威信 ISHIN Premium so special? The secret is L-Cystine, an amino acid which stimulates the production of glutathione, an antioxidant that exists in the body which several studies have shown produce a skin whitening-effect. L-Cystine is a widely used whitening supplement in Japan.

But that’s not all— L-Cystine also activates your skin’s turnover, which gives you a brighter complexion, and has an antioxidant effect that stimulates the activity of glutathione peroxidase enzymes, which protect the skin from reactive oxygen species (ROS). It also represses the activity of tyrosinase enzymes, which come from ROS and are involved in the production of melanin.

When you incorporate 威信 ISHIN Premium in your daily supplement regimen, not only will you feel healthier, you’ll get the added side effect of healthy glowing skin that shines.
