It is amazinggg!!
This Beauty of Joseon Dynasty Cream from HIRAYA COS is a winter skincare lifesaver. It’s rich and nourishing without being too thick, so it absorbs quickly and keeps my skin hydrated all day long. Even in the coldest weather, my skin feels soft, smooth, and deeply moisturized. If you're looking for a reliable moisturizer to keep your skin healthy through winter, this one’s a winner!

Face cream
The cream is supergood.I liked it

Absolutely obsessed
My skin is glowing after using this for a few weeks - I’ve had multiple people comment on how good my skin is looking AND my massage therapist told me she thought I was 23 (I’m almost 30). 10/10

Just what I needed for winter
Would recommend this product. I have combo skin and it’s very dry during the winter and this helps my skin feel moisturized
