Aging is accompanied by the appearance of wrinkles.
Static wrinkles are formed due to aging, unhealthy lifestyle, long exposure to the sun. As we age, the skin produces much less collagen, which is manifested by wrinkles. Wrinkles are more noticeable in people with dry skin and people who have lost facial fat.
Unlike static wrinkles, facial wrinkles appear as a result of strong activity of muscles expressing facial emotions. Any emotion can become the reason for the formation of mimic wrinkles or lines.
Over time, the skin loses its elasticity and the wrinkles gain depth, therefore, they remain permanently on the face.
Mimic wrinkles can be straightened in aesthetic centers with appropriate cosmetic injection. The initial result is noticeable in 2-3 days, and the full effect is obtained 1 week after the procedure.
