Ester C Serum

A silky, smooth, transparent fluid is the carrier for the unique activity of oil-soluble vitamin C – Ascorbyl Tetraisopalmitate, which is broken down into free vitamin C during use on the skin. This sophisticated, stable vitamin C derivative offers multiple skincare benefits.


  • Superior percutaneous absorption due to its oil-soluble structure.
  • Protects the skin from lipid peroxidation and skin aging.
  • Excellent stability even when exposed to elevated temperature and light.
  • Minimal discoloration, especially when compared to water-soluble vitamin C that darkens within only a few days.
  • Acts as a potent SOD-like antioxidant with a revitalizing effect on the skin.
  • Compatible with other naturally derived cosmetic oils. 
  • The serum formulation is smooth and non-tacky and is readily absorbed by the skin.
  • It is equally beneficial for dry and normal or combination skin types for maintaining the skin soft and smooth.


For best results, especially when used for dry skin, it is recommended to first quench the skin with moisture by using a hydrous serum such as “First of all”. Once absorbed, use a few drops of this serum, spreading them to all facial areas and décolleté. Makeup foundation or protective day cream may be applied on top.

For external use only * Use for designated purposes only and according to directions * Avoid eye contact * Avoid use if sensitive to any of the ingredients * Keep out of children’s reach. * Discontinue use or see a doctor if rash or irritation occur. *Do not use on broken skin.
