Formulated by Ildong Pharmaceutical · Seoul
First Lab is Ildong Pharmaceutical's skincare research institute — built on the fermentation science behind Biovita, Korea's first probiotic, launched in 1959.
The science
Skin hosts trillions of microorganisms that keep moisture in and irritants out. Strip that biome with harsh actives and the barrier weakens — redness, sensitivity, and breakouts follow. First Lab formulas are built around a Lactobacillus ferment lysate that only Ildong Pharmaceutical is licensed to use, feeding the skin's own flora instead of stripping it.
"A drop of science."
The line

"Pure lab, where bare skin glows."
1959
Ildong Pharmaceutical launched Korea's first commercial lactobacillus product decades before probiotics became a skincare trend.

Three weeks in and the tightness I used to get from my old retinol routine is just gone. My skin looks calmer, not just "hydrated."

I've tried every "clean" serum out there. This is the first one where I can actually feel the difference by day three.

Sensitive, rosacea-prone skin here. The Probiotic Serum is the only new product I've introduced in two years that hasn't caused a flare.

The cleanser doesn't leave that tight, squeaky feeling I used to chase. My skin actually feels calmer right after washing.

Probiotic Cleanser
★★★★☆
Rich without being heavy — I layer it over the serum at night and wake up without any dry patches around my nose.

The moisture mask is my Sunday reset. Skin looks plump the next morning without any of the tightness sheet masks usually leave.

First sunscreen that hasn't pilled under makeup or left a white cast. It's become the one step I never skip.
