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

The Brightening Serum

"Whilst I don’t use this product on a daily basis when I do my skin feels and looks amazing. It is not an oily serum and gently folds into the skin leaving it looking bright and clear."

— Deborah N. (5/5)

Very pleased.

"I had my first bottle in the space nk advent calendar last year and I’ve really noticed a difference in my skins texture, it’s a nice light formula too. I’ve just bought my second bottle."

— Zoe S. (5/5)

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."

— Pavli M. (5/5)
