When Dr Alexandrides started his practice, it was difficult for him to find skincare that would help heal the skin more efficiently after cosmetic procedures.

Dedicated to continuous research he discovered that skin ages faster in space because of environmental extremes. For that reason he sought collaboration of space scientists responsible for the wellbeing of astronauts. Together they created the patented NAC Y² formula.
