Creatine is a naturally occurring compound that supports cellular energy metabolism and is used in skincare to help improve skin firmness, support collagen synthesis, and reduce visible signs of aging. It functions as a skin-conditioning and antioxidant-supporting active.

Contact dermatitis or allergic reaction | Very rare | Isolated cases; uncommon given creatine's good tolerability profile. |
