Sebum Film Protection

Sebum film is the skin’s natural protective barrier , which can:

  • Water Locking.
  • Prevents excessive evaporation of skin moisture, reduces trans-epidermal water loss (TEWL).
  • Brings flexibility and smoothness to the skin.
  • Protection – Protects the skin from harmful agents entering, such as bacteria and environmental pollutants.
  • Sebum film has a weakly acidic pH value which can suppress the growth of bacteria and other microorganisms.

When sebum film damages….will directly affect the skin barrier function, which leads to:

  • Increasing trans-epidermal water loss
  • Dry skin
  • Fine lines and wrinkles
  • Sensitive, susceptible to external environmental stimuli
  • Bacterial infection easily
  • Inflamed easily


  • Belonged to the family of lipid molecules
  • Is the main component of the cell lipid layer, accounting for 40-60%
  • Possesses important function: Preventing dispersion of water and protecting from outer irritation

Healthy skin can prevent environmental stimuli and to avoid excessive water loss.
Ceramide can catch plenty of water in the stratum corneum, skin is full of water at all times, so that the skin supple!

Ceramide’s function:

  • The most important component of the cell lipid layer
  • Repair spoilt sebum film
  • Protects the skin from harmful agents entering
  • Reduce skin sensitivity
  • Increase water locking function
  • Reduce fine lines and wrinkles
  •  Restore healthy skin
