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

You would need to be examined in person to determine what is best for you.  You are rather young to need anything, but you would need to be seen in person.

It is highly unusual to have excess skin at your age and one has to think about the outside factors that are causing wrinkles in your forehead such is compensation for congenital droopy eyelids. Injection of botulinum toxin under this scenario would be ill advised since it will take your compensation away and you will have difficulty keeping your eyes open. You want  to consult a plastic surgeon who is familiar with this type of rare wrinkling at a young age. The only good indication for the use of botulinum toxin at your age would be spasm in the forehead muscles, especially if is causing headaches for you.

You can do filler into this area, but you will still have lines during movement.  The best treatment would be Botox, and that is very safe and easy to do.  I suggest seeking a cosmetic consultation with a cosmetic dermatologist or plastic surgeon with experience.  In an person consultation is needed.  Best, Dr. Emer.

It sounds as though you may be a good candidate for Botox and skin tightening with Pelleve or Ultherapy.   Please see a board-certified dermatologist or plastic surgeoon for an evaluation.

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.
