Botox stops some muscle contractions that cause wrinkles, but it doesn’t entirely stop facial expressions. Depending upon which area is treated, you will still be able to smile, laugh, and make countless other facial expressions. Some expressions will be minimized, but it can be tastefully done so your face will not look frozen or expressionless. The key difference between your appearance pre-Botox and post-treatment is the wrinkling. After Botox, there should be a significant reduction in wrinkling of that particular area. The end result, your skin will look smoother and younger when you smile, frown, look surprised and/or are simply relaxed.
