№73 Barrier Repair Serum

The Barrier Repair Serum was developed by Dr. Libi Hershkovich and Dr. Inna Szalontay allowing the skin to  access a combination of many powerful ingredients in one product, which strengthen the effect  of one another. Regular use of this natural yet complex serum  helps to support the skin’s protective function,  contributing to a more balanced sebaceous  gland activity and reinforcing the hydrolipidic  mantle, which can aid in maintaining moisture  levels and supporting the skin’s natural barrier  against external elements. This serum is designed to assist in keeping the skin hydrated and  is suitable for dry, sensitive, and flaky skin types. warning: Store in a cool, dark place. Avoid  placing in direct sunlight. For external use only.  Keep out of reach of children.

Product history

In your hands is the result of research efforts of  six generations of female cosmetologists from  the same family. Each generation embraced the  scientific thought of their era and embedded  this body of knowledge into the products of Libi  & Daughters. Modern science has endowed cosmetology  with a powerful toolkit to achieve its goals. One  of these is a deeper understanding of the physiology of skin and the ability to influence the various inner processes in a more granular fashion.  Thanks to new forms, long-studied components  of cosmetic preparations have gained the ability  to be seamlessly delivered to the necessary skin  layers and induce programmed effects.
