Dr.YOON Derma Skin's DCCM4™ (Defined Cell Culture Media4) is a stem cell culture solution,

which contains 43 key components for skin stem cell growth developed through a patented technology of

Dr.YOON, who is an expert of the field.

A stem cell is a cell with the unique ability to develop into specialized cell types in the body.

Stem cells have potential to reproduce cells through cell division and become various kinds of functional cells.

In particular, skin stem cells are present in the basal layer of hair follicles and epidermis and dermis.

They produce cells needed for the regeneration of hair and epidermis.

Since the dense structure of skin functions as an external barrier to the body, it is low in absorption.

Dr.YOON has developed a very special recipe that allows the culture medium to be well absorbed into the

skin to facilitate growth of skin stem cells in hair follicles by appropriately adjusting the concentration of hydrogen ions,

osmotic pressure and ion balance. This technique was named DCCM4™(Definitive Cell Culture Solution4).

Dr.YOON Derma Skin's DCCM4 ™(Definitive Cell Culture Solution4) is a special culture medium

developed for the cultivation of skin stem cells and does not contain stem cells extracted from human body.

Dr.YOON Derma Skin's DCCM4™ (Defined Cell Culture Solution4) uses 43 special ingredients developed

through a patented technology and includes minerals, amino acids, vitamins, fatty acids and energy sources of

pharmaceutical grade. The DCCM4™, in particular, is a safe ingredient listed in KCID and ICID,

which has patent registration and numerous academic research results that prove its safety.

DCCM4™ (Defined Cell Culture Solution4) is a special substance consisting of all necessary nutrients for growth of

skin stem cells. It is a pure culture solution, not a stem cell culture;

it is also unrelated to the stem cells extracted from the human body.
