💧 Introduction
Do you apply your skincare every day, but your skin remains dull, dehydrated or prone to redness?
The problem may not be your products… but your weakened skin barrier .
In K-beauty, the skin barrier — also called the hydrolipidic film — is at the heart of all routines.
It's your skin's protective shield : when it's weakened, your entire skin balance collapses.
Find out why it's so important to preserve it and how Korean skincare can repair it lastingly 🌿
🧠 What is the skin barrier?
The skin barrier is made up of lipids, water and cells that protect the skin from external aggressions (pollution, cold, UV rays, bacteria, etc.).
It acts like a brick wall:
-
cells are the bricks 🧱
-
lipids are the cement 🧴
When this wall is strong, the skin is soft, supple and radiant.
But when it becomes damaged — due to stress, over-cleansing or overly powerful active ingredients — the skin becomes:
❌ Dehydrated
❌ Responsive
❌ Prone to pimples and redness
🌿 Signs of a weakened skin barrier
-
Persistent tightness, even after applying cream
-
Frequent redness and tingling
-
Pimples or micro-inflammations
-
Skin that no longer “drinks” the treatments
-
Dull and uneven complexion
👉 If you recognize yourself in these symptoms, it's time to adopt a restorative routine inspired by Korean cosmetics.
