The skin under the eye is very delicate and thin which is why hallows and wrinkles can appear. Because of this thin skin you have to be careful about adding HA fillers under the eye. An alternative and natural approach is PRP injections under the eyes. PRP, or Platelet Rich Plasma, is derived from your own bodies blood and is rich is growth factors and stem cells. These growth factor and stem cells will start thicken the delicate skin under the eye and in return start to reduce the appearance of hallows, dark circles, and wrinkles naturally.
