What is sensitive skin?

Even with different external irritation such as temperature changes, low humidity, ticks, dust and bacteria, we can still protect and keep skin healthy and beautiful – thanks to our skin’s barrier function. However, once skin’s barrier function is weakened, skin becomes sensitive and more vulnerable to external irritation.

A lipid known as ceramide found in skin’s stratum corneum (skin’s outer layer) is essential to skin’s barrier function. Learn more about the relation between ceramide and sensitive skin in the diagram below.

Sensitive skin is caused by a lack of ceramide: Ceramide is found in the stratum corneum (skin’s outer layer) and has two main functions:
1. Protect our body against external irritation.
2. Retain moisture within the body.
Research proves that people with sensitive skin lack ceramide, which causes skin’s barrier function to weaken.

In this condition, external irritants can penetrate skin more easily; therefore it is important to protect skin’s ceramide function. Skin that has sufficient ceramide can fully realize its barrier function, protecting body against external irritation and locking moisture in skin to keep it hydrated.
