How to Say Goodbye
to Flaky, Troubled Skin
: Meet the Energy of Jeju Cell

If your skin feels unusually dry and rough,
and looks visibly tired,
it may be more than simple dryness.
Your skin may be depleted of moisture,
or its balance may have been disrupted by stress.
At times like this,
your skin needs a different kind of energy.
The power to replenish moisture,
and the power to restore weakened skin condition.
Here are two energies
discovered in Jeju nature.
A Welcome Rain for Thirsty Skin
What dry skin needs is
not simply more water,
but a moisture environment
that stays longer.
Jeju Natural Moisture Cell contains
prickly pear that preserves moisture
even in harsh environments,
aloe with moisturizing and soothing energy,
camellia flower that adds radiance and elasticity,
and cornflower that gently comforts the skin.
Camellia Flower | Antioxidant · Moisturizing
Phenolic compounds and DPPH radical scavenging activity confirmed
Korean J. Medicinal Crop Sci., 2005
Cornflower | Antioxidant · Soothing
DPPH/ABTS radical scavenging activity and NO production inhibition confirmed
J. Agric. Life Environ. Sci., 2024
Prickly Pear | Antioxidant · Brightening
Concentration-dependent reducing power and melanin production inhibition confirmed
J. East Asian Soc. Diet Life, 2023
Aloe | Moisturizing · Wrinkle Care
MMP-1 production and hyaluronidase activity inhibition confirmed
J. Kor. Soc. Cosm., 2013; Phytother. Res., 2013

With a Stronger Barrier,
Moisture Stays Longer
Jeju Natural Moisture Cell
replenishes moisture in dry skin
and supports barrier care
to help prevent moisture from escaping,
allowing the skin to hold hydration more firmly.
Cell Proliferation Effect
At 1% concentration, cell proliferation was improved by 152.3% compared with the control group,
suggesting potential to support damaged skin cell recovery and skin barrier strengthening.

Moisturizing Effect
After 120 minutes of application, moisture loss was reduced to approximately 50% compared with the 20% comparison group,
while moisture evaporation inhibition improved by up to 2-fold.

Restoring Weakened Skin Condition
If skin troubles keep appearing,
it may be a sign that your skin
has become more sensitive.
Jeju Natural Regeneration Cell contains
calendula that helps protect skin from damage,
green tea rich in catechins,
wild ginseng that adds elastic energy,
and camphor tree leaf that wraps the skin
like a protective layer.
Camphor Tree | Antioxidant · Anti-inflammatory · Protective
TNF-α production inhibition, antioxidant activity, and antifungal activity confirmed
Cheju J. Life Sci., 2002; Asian J. Beauty Cosmetol., 2016; Ind. Crops Prod., 2013
Green Tea | Antioxidant · Anti-inflammatory · Wrinkle Care
DPPH scavenging activity, NO/iNOS inhibition, and collagenase inhibition confirmed
Chem-Biol. Interact., 2016; J. Invest. Cosmetol., 2013
Calendula | Skin Regeneration · Antioxidant
Quercetin glycoside migration and antioxidant activity confirmed
J. Ethnopharmacol., 2017; Appl. Chem. Eng., 2016
Wild Ginseng | Elasticity · Barrier Care
Activities related to collagen synthesis and ceramide biosynthesis confirmed
CoSeedBioPharm Own Experiment; Int. Wound J., 2016; J. Ginseng Res., 2012

Helping Skin Return to a Healthy Rhythm
Jeju Natural Regeneration Cell
supports regeneration and elasticity care
to rebalance weakened skin
and help skin tired from external stressors
recover a healthier condition.
The regenerative energy of calendula,
green tea, wild ginseng, and camphor tree leaf
helps tired skin regain a healthier condition.
Skin Regeneration Effect
In a cell migration assay using HDFn cells, migration increased as the treatment concentration of Jeju Natural Regeneration Cell increased,
indirectly confirming its potential skin regeneration effect.

Skin Elasticity Effect
As the treatment concentration increased, elastase activity decreased and collagen production increased.
In particular, at 200 μg/mL, elastase activity decreased to approximately 60%, while collagen production increased to approximately 125%,
confirming its elasticity-improving effect.

Jeju Energy Fermented with 400 Years of Wisdom
Jeju’s plant energy is
refined once more
through Shindari fermentation,
a traditional fermentation technique.
It delicately unlocks
the active compounds within plants
and delivers nature’s vitality
to the skin more deeply and gently.
Jeju’s Traditional Fermentation Method, “Shindari”
Water and nuruk are added to rice that has begun to sour slightly, then fermented.
During nuruk fermentation, layers of bubbles form as if alive and breathing.
Depending on the efficacy of the fermenting strains, various benefits may be expected.
Through microbial fermentation, active components may increase, helping maximize existing efficacy.
The fermentation process helps reduce the particle size of active compounds, improving absorption.
Through microbial digestion and decomposition, toxic substances are broken down,
enabling safer use as an ingredient and supporting the potential for natural preservative properties.

Jeju Sea Water
Jeju lava seawater promotes the production of NMF, which is essential for skin hydration, and facilitates moisture movement within the skin to strengthen barrier function and provide overall moisturizing benefits.
Jeju lava seawater promotes keratinocyte migration, accelerating the wound closure process.
