Some skin problems start from dryness.
Modern-day skin is vulnerable to
becoming sensitive skin
Nowadays, many women have skin concerns related to dryness.
Due to repeated exposure to UV rays and frequent exposure to changes in temperature and humidity, skin can't keep up with the changes in its environment, and its barrier function declines further and further.
A decline in the barrier function is a sign known to foreshadow a shift to sensitive skin.
When it comes to modern-day skin, not only are there people with sensitive skin but there is a tendency for even skin with few problems to be prone to becoming sensitive.
To keep skin healthy, it's important to make a point of moisturizing as part of your everyday care and ensuring that your skin doesn't run out of moisture.
Intercellular lipids in the stratum corneum hold water and link the cells together, and the sebum film on the skin's surface also plays a role, protecting the skin from a variety of irritants. Water and oil content are preserved in a good balance, plumping and smoothing fine lines, so skin is soft and smooth.
Intercellular lipids are in short supply, triggering the evaporation of moisture, and the stratum corneum is filled with gaps. Skin becomes vulnerable to the effects of external irritants, and the vicious cycle is repeated. Water and oil content are lacking, and the sebum film doesn't function adequately, so fine lines are disorderly, skin is hard, and toughness, powderiness, and peeling become noticeable.
