Mimic wrinkles arise on account of contraction of mimic muscles. Dynamic wrinkles occur when we smile, laugh or frown, and the delicate muscles underlying aging skin contract. This causes progressive creation of wrinkles. If we immobilize the muscles, the skin will stop creasing. Summing, muscles immobilization averts formation of wrinkles.
In our clinic, to achieve the best results, we recommend botulin toxin (Botox, Azzalure).
