The Brightening Eye Cream

From £26

People in Japan have long believed that a true healthy glow comes from deep within.

They often turned to nutrient-rich ingredients from the kitchen to nurture their bodies and complexions. Japanese plum (nanko ume), known as the queen of plums, was once used in at-home beauty rituals to help brighten skin, creating an inner glow referred to as kagayaki.

Reviews

Fabulous

"I have used Tatcha for years so decided to try this serum as a new addition to my morning routine. My skin is definitely brighter from using and it drys quickly into the skin and then layers beautifully with my next products. Doesn’t cause any pilling and makeup applies well on top. Also got the matching eye cream but finished. Another fabulous product for everyday and really happy with my results so far."

The best vitamin C serum I have ever tried

"I’ve been absolutely loving this serum. My skin has looked so much brighter and more radiant since I started using it, and it gives me that healthy glow without feeling heavy or greasy. I’ve also noticed that some of my pigmentation marks have started to fade, and my overall skin tone looks much more even. It absorbs really quickly and layers beautifully with the rest of my skincare and makeup. It’s definitely become one of those products I look forward to using every day. A bit of a splurge, but honestly worth it for the results."
