I'm only 19 & I have excessive skin on my forehead. How I can get rid of loose skin without Botox or Surgery? (photo)

Truly lax skin of the face in a young person may indicate a medical or genetic condition so first thing is to have an evaluation by a dermatologist to ensure that the skin is normal.  Your best options for non surgical/non chemical approaches to skin tightening are Thermage and Ultherapy.  Thermage utilizes radiofrequency energy and Ultherapy utilizes ultrasound energy to heat up the layers under the skin to stimulate new, tighter collagen resulting in firming and tightening (Thermage) as well as lifting (Ultherapy).  Results are moderate, not dramatic as one can see with surgery, but patients who do not want surgery can be very pleased. 

Although loose forehead skin can lead to more wrinkling with movement of the muscles, and botox would quiet the movement, there are other alternatives.  Using radiofrequency or unltrasonic skin tightening such as Exilix, Thermage or Ulthera can tighten the skin, thereby reducing the wrinkles.  These usually require one or two treatments with no down time.  The results are usually very satisfactory and long lasting.
