Creatine is an amino-acid derivative, naturally occuring in vertebrates, mainly present in muscles and brain. It is involved in the energy metabolism, helping to supply all cells in energy, mainly muscle cells.

It is supplied among others by Evonik under the tradename Tego Cosmo C 100. Evonik claims the following skin care benefits :

• Revitalization of cell energy metabolism
• Supports skin protection
• Moisturizer

Evonik explains as follows the necessity of a well-working cells energy metabolism : “the physiological fatigue of skin evidenced by the early signes of aging is caused by stress and environmental influences. The consequence is a decrease of the energy amount stored in the celles followed by a suppressed capability to synthesize proteins such as collagen, elastin and keratin. Additionnally, cells experience increased oxidative stress as they age, increasing the amount of energy required for internal defenses. So a well-working energy metabolism is essential for skin cells vitality”.
