Our Science
Biomembrane
Skin Science.
SEISUI is built on a biomimetic membrane: a blend of skin-identical lipids that works together with vitamin A, vitamin C and a peptide.
Together, they help your skin renew itself and stay strong.
All your skin needs. In one cream.

The Power of Encapsulated Retinal
Powerful Skin
Renewal
SEISUI uses encapsulated retinaldehyde, a highly effective form of vitamin A just one conversion step away from retinoic acid, the form that acts directly on skin cells. That puts it in the sweet spot: reported to work up to 11× faster than standard retinol, yet gentler than prescription retinoic acid.
In clinical studies, retinaldehyde improved skin texture and hydration and reduced moisture loss after three months of use. Another study showed improvements in wrinkle depth and elasticity.
SEISUI’s encapsulation and airless pump shield retinal from light and oxygen, and the formula surrounds it with skin-identical lipids, ceramides, phospholipids and nourishing vitamins.
The result: the benefits of retinal, with the barrier support that makes it gentle enough for sensitive skin.
Built Like Your Skin
Skin-Identical
Technology
Most creams coat the skin. SEISUI is made like skin.
Phospholipids, ceramides and skin-identical lipids form thin, stacked layers, just like the natural layers of your skin barrier.
Phospholipids
Similar to your skin's own lipids, so the cream absorbs easily
Ceramides
Strengthen and protect your natural skin barrier
Skin-Identical Lipids
Work with your skin's own structure
Why Biomimetic
01
Membrane-Based
A phospholipid membrane is the base of the formula. It's the second ingredient, right after water.
02
Complete Barrier Lipids
Five ceramides with cholesterol and phytosphingosine, the lipid family your barrier is built from.
03
Renewal Without Compromise
Encapsulated retinal and barrier repair work together, in one step.
Everything Your Skin Needs.
Nothing More.
No unnecessary ingredients. No fragrance. No overload. Just a carefully designed formula that works with your skin.
Beauty is within your reach. No complicated routine needed.
One evening step instead of
