Achieve your dream skin while you dream with the help of a very special ingredient found only in Japan, available only at Kita Skin.

Sacran is your sleep's new best friend

Superior hydration

Hydration capability is measured by an ingredient's moisture retention capacity a.k.a how much water an ingredient can hold relative to its weight.

Sacran holds 6,000 times its weight in water, giving it the highest hydration capability of any ingredient ever.

Proper hydration at night is vital for preventing dryness and dehydration in the morning, and Sacran hydrates the best.

Overnight moisture balance

Minimising transepidermal water loss (TEWL), a.k.a how effective an ingredient prevents moisture loss from your skin, is the second measure of hydration capability.

When applied, Sacran uniquely forms a protective and breathable mesh on your skin which locks in hydration and minimises TEWL far better than any other ingredient.


This is vital at night when your skin loses the most moisture, so you can wake up to hydrated, plump and glowing skin.

Skin barrier strengthening

Beauty sleep is more than just a saying — sleep is a vital part of repairing damage and restoring your skin barrier (the outermost layer of skin, protecting you against environmental stressors moisture loss).

Sacran enhances your skin barrier function through the protective mesh that locks in hydration and acts as a barrier against external stressors.

This is especially important at night when your skin is in repair mode, ensuring you wake up with a stronger, more resilient complexion.

Reduce fine lines & wrinkles

Declining natural moisturising factors causes aging skin to become prone to dehydration and a weakened skin barrier, leading to dryness and reduced skin volume, fine lines and wrinkles.

Sacran helps combat this by replenishing and locking in moisture to plump the skin from within, and strengthens the skin’s barrier, helping prevent future moisture loss.

By maintaining a well-hydrated, plump complexion, you can visibly reduce the appearance of fine lines and wrinkles, and achieve a firmer, youthful, and radiant complexion.

This product arrived today. It is unscented, a plus I think - goes on smoothly - I’ll let you all know after 2 weeks how it is but so far I do like it

When I discovered this serum, my skin transformed. It feels lightweight and fast drying, but my skin has never been more hydrated. I've also noticed that it's helped reduce impurities and breakouts. This serum is really something else.
