Being aware of your sensitive skin and treating it with specific products can make a difference. The tolerance threshold of sensitive skin is lower than usual. It suffers discomfort including tightness, redness or itchiness. This is because the skin does not have sufficient protection, due to unbalance of the hydrolipidic layer. The barrier function has weakened elasticity and effectiveness and small fissures and flaking appear, facilitating the penetration of irritating substances.
