Silikon 1000 is a permanent filler, so once it’s been injected it can only be surgically removed. However, as we do continue to age, you may continue to lose collagen, elasticity and fat, so you may see hollowness over time. Silikon 1000 is fixed into place with collagen so you actually may see some additional clumping of the skin. I do not recommend silicone under the eyes because the skin is very thin in that area which means if the Silikon 1000 is not properly placed you can have lumps under the skin. I do recommend the use of Restylane exclusively for the eye area and in the event the patient isn’t satisfied the filler can be melted and removed with hyaluronidase.
