Skin barrier damage
When the skin's outer protective layer is weakened, it may lose more moisture and react more easily to external factors.
Learn about a weakened skin barrierSensitive Skin, Redness & Irritation
Guide by skin concern · Korean cosmetic science
Reactive skin may show redness, burning, tingling, tightness or discomfort. Sometimes this response is linked to a weakened skin barrier, dryness, intensive use of active ingredients or environmental factors.
A gentle, consistent skincare routine focuses on mild cleansing, maintaining hydration, supporting the skin barrier and gradually reintroducing active ingredients according to individual tolerance.
✦
In short
When skin is irritated, it is often better to simplify the routine: reduce overload, avoid friction and too many active ingredients, and prioritize hydration, comfort and skin barrier support.
Understanding skin reactivity
Why does skin become sensitive and irritated?
Skin may become more sensitive temporarily or persistently when the skin barrier is weakened, when too many active ingredients are used, during periods of dryness and dehydration, or due to environmental conditions such as sun, wind, cold and dry air.
Overuse of active ingredients
Introducing several active ingredients too quickly, frequent exfoliation or constantly changing the routine may increase sensitivity and discomfort.
Dryness and dehydration
A lack of lipids or water in the upper layers of the skin may appear as tightness, roughness and increased sensitivity.
Learn about dryness and dehydrationEnvironmental factors
Sun, wind, dry weather, air conditioning and sudden temperature changes may affect skin comfort and skin barrier function.
Three related, but different, conditions
Sensitivity, redness and irritation - what is the difference?
These terms often appear together, but they describe different aspects of skin reactivity. Understanding the difference can help clarify what the skin is experiencing and what may be worth changing in the routine.
Sensitivity
A tendency for the skin to react quickly to skincare products, temperature changes or environmental factors.
Redness
A visible change in skin tone that may appear temporarily in response to heat, friction, a new product or an environmental factor.
Irritation
Burning, tingling, tightness or discomfort that may appear after exposure to a substance or factor the skin does not tolerate well.
Persistent redness, pain, swelling, significant itching or recurring worsening should be evaluated by a dermatologist or another medical professional.
The skin's first line of defense
What happens to the skin barrier?
A healthy skin barrier helps keep water in the skin and reduce the penetration of external factors. When it becomes weakened, water loss may increase and the skin may feel drier, tighter or more sensitive.

When skin needs less
What should you avoid when skin is irritated?
During irritation, it is better to reduce stress on the skin and prioritize a simple, consistent and gentle routine.
Frequent exfoliation
Too much mechanical or chemical exfoliation may increase dryness and discomfort.
Too many active ingredients
Adding several active ingredients at once makes it harder to understand what the skin tolerates well.
Very hot water
It is better to use lukewarm water when cleansing the face.
Rubbing and friction
Vigorous towel drying or intensive massage is not suitable for irritated skin.
Over-cleansing
Cleaning too frequently or too aggressively may compromise skin comfort.
Frequently changing products
A consistent routine makes it easier to identify which products suit the skin and which do not.
Fewer products, more consistency.

Frequently asked questions
Sensitivity, redness and irritation - questions and answers
What causes skin to become sensitive?
Sensitivity may be associated with a weakened skin barrier, dryness, overuse of active ingredients, environmental changes or an individual tendency toward skin reactivity.
How can you tell if the skin barrier is weakened?
Possible signs include tightness, dryness, roughness, tingling or increased reactivity to products the skin previously tolerated well. Similar symptoms can also have other causes.
Is niacinamide suitable for sensitive skin?
Niacinamide can also be included in a sensitive-skin routine, but tolerance varies from person to person. At a 10% concentration, it is recommended to start gradually and monitor the skin's response.
Which ingredients are suitable for sensitive, redness-prone skin?
Ingredients that support hydration and the skin barrier, such as panthenol, hyaluronic acid, ceramides and squalane, can fit well into a gentle routine. The choice depends on skin condition and individual tolerance.
What should you do if your skin becomes irritated after using a new product?
Temporarily stop using the suspected product, simplify the routine and avoid introducing new active ingredients. If the reaction is strong, persistent or worsening, seek advice from a medical professional.
How long does it take for skin to calm down?
There is no fixed timeframe. It depends on the cause of irritation, the intensity of the response and the condition of the skin barrier. If there is no improvement or significant symptoms appear, it is advisable to seek medical advice.
