Our review

The inspiration for 111SKIN, Dr. Yannis originally developed a super serum to aid post-surgical repair. Word spread quickly about this powerful formula and its incredible ability to support and protect the skin. Only a small amount of this lighter version of our serum is needed to nourish and plump skin. It will come to the rescue if your skin’s been exposed to extreme conditions such as the ski slope or safari sun. The perfect repair serum for oilier skin types and humid environments, our lighter version will thoroughly and reliably rescue your skin and bring it back to life.
