#3. 4 Skin Habits a Skincare CEO in Her 50s Swears By
# After 20 years of making skincare,
here's what I actually do.
The most common question I get:
"How do you take care of your skin?"
People expect a cutting-edge serum recommendation.
My answer is always the same:
great skin starts with order, not with great products.
Skin has the capacity to heal itself.
My job is to stop getting in the way.
That's what well-aging means to me.
#01. Great skin starts with how you cleanse.
Most people invest heavily in serums,
then grab whatever cleanser is on sale.
Alkaline cleanser?
A highly alkaline cleanser strips
your barrier along with the grime.
Gentle cleanser?
An overly gentle one leaves sebum
and buildup that quietly causes breakouts.
After 20+ years of formulating, my conclusion was simple:
clean thoroughly, and protect the barrier while you do it.
Our answer: a mildly acidic cleanser
precisely calibrated to pH 5.0–6.0.
Makeup and impurities come off completely;
the skin barrier stays intact.
Post-cleanse moisture retention tested at 99.4%.
That's why your skin shouldn't feel tight after washing.
Skincare starts the moment you cleanse.

#2. Want younger-looking skin?
Cool it down first.
After hiking or a long day outdoors, my skin runs hot.
My old instinct was to layer on more cream.
It usually made things worse.
Heat from UV exposure, stress, or friction raises
skin's surface temperature —
making it redden faster and age more quickly.
Piling on rich cream at that point isn't the answer.
Calming it is.
After laser treatments, a day in the sun, a workout —
your first skincare move should be soothing, not nourishing.
"In traditional Korean medicine, raising your core body temperature
activates immunity. But skin surface temperature works differently.
If you want to age well, cool your skin down first"
One more thing:
wrinkles don't start at your face.
They start at your scalp. Use a silicone-free shampoo,
skip the hot water, and keep your scalp cool.
It matters more than most people realize.
#3. Combination skin?
Tackle inner dryness first.
Skin that's oily on the surface but dry and tight underneath —
Koreans call it su-bu-ji, and it's one of the most
common concerns I hear.
It looks like oily skin, but it's not really.
Here's what happens: you strip the oil with a strong cleanser,
your skin rushes sebum back to the surface to compensate,
and you end up with a face that's parched inside but shiny outside.
One day, the fine lines show up fast.
The solution isn't to strip more —
it's to deliver real hydration beneath the surface.
Our Youthbiotics line ferments white lotus leaf
(high in antioxidants) for 168 hours.
The fermentation breaks compounds
into smaller molecules the skin can actually absorb,
with 8 probiotic strains to reinforce the barrier from within.

02.Inner hydration — Youthbiotics Lotus Probiotic Concentrate “All-in-One” Serum (80ml) — 114% improvement in moisture retention, clinically tested
03.Moisture seal — Youthbiotics Lotus Probiotic Concentrate Cream (50ml)
#4. Skipping sunscreen is
throwing your skincare away.
It doesn't matter how much you spend on a serum.
Without SPF, it's like pouring water into a cracked jar.
UV rays break down everything your moisturizer worked to build.
I wear sunscreen every single day —
commuting, hiking, driving. Every season.
Our sunscreen is SPF50+/PA++++ with triple functionality:
UV protection, brightening, and anti-wrinkle.
No white cast, no heavy finish.
It's also the product I reach for most from our own line.

02.Jeju Botanical Daily Tone-Up Sunscreen SPF50+/PA++++ (50ml)
"Good skin isn't a secret.
It's a practice."
Cleanse well. Manage heat. Address inner dryness.
Protect against UV. Consistently, every day.
