90 Days of Slow Curation. A Waterless, Nutrient-Rich Cleansing Ritual for Timeless Skin Longevity.

The World’s First 100% Waterless Organic Milk Bar — Crafted by Artisan Dairy Farmers.

Japanese milk soap doesn't actually use real milk. And nutrient-rich whey is discarded in large quantities...
Typical cosmetics and soaps are 30-60% "water"
AIKA SOAP uses a 100% waterless formula, not a single drop of water
Made with only beauty ingredients, based on organic raw milk from pasture-raised Jersey cows in Fukuoka Prefecture and raw whey that would have been discarded

A "relay of vitality" from all over Japan, condensed into one box
AIKA SOAP sources "first-class natural ingredients" from trusted producers across Japan,
upcycling them and transforming them into a world-class luxury product

Two individualities packed into one box
White: Primarily for high moisturizing and damage care
Give the finest milk to your skin and heart after a hard day
"Organic raw milk and whey" rich in amino acids, plus 7 types of plant oils including shea butter, intensely care for UV and dryness damage from the day while you sleep

Green: Primarily for cleansing and barrier function
"Toyama Clay (Montmorillonite)" with its porous structure magnetically adsorbs and cleanses atmospheric pollutants and oxidized sebum from the day with its ionic power.
At the same time, the high skin-conditioning and antibacterial power of traditional Japanese "naturally grown indigo" soothes minor inflammation from the day, and "Argan Oil," extremely rich in essential fatty acids (oleic acid, linoleic acid), repairs the skin's lipid layer, rebuilding a strong skin barrier.

Fukuoka Prefecture: Organic Jersey farmer's raw milk, cheese factory upcycled whey, and support facility for people with disabilities
"Organic raw milk and upcycled whey (environmentally friendly beauty ingredients)" from Jersey cows raised in abundant nature form the foundation of moisture
Each product is carefully packed and shipped by staff at the support facility for people with disabilities

Okayama Prefecture: Organic farmer's beets
"Organic beets", bathed in abundant sunlight, give the skin a firm, plump feeling and a clear, translucent glow

Tokushima Prefecture: Naturally grown indigo from organic farmers
