Judicious use of Restylane can be very effective for the crease lines you noted. I have used it effectively for so-called "tear trough" deformity beneath the lower lids. Bruising is always a possibility with any injection in this thin tissue.
Hi Dr Rosenberg
Thank you for the reply. Although 'symmetrical', in that they are forming on both sides, they are not identical, the one under my right eye is more of a straight crease line, whilst under the left is a more semi-circular one. I have narrowed it down to sleeping position as there is no other explanation I can find. If I push my cheek up as it would be when sleeping on my side (against a pillow), the skin folds along these lines. They are not developing due to expression.
Therefore I think that Botox is probably not useful, but maybe Restylane or Perlane to give microscopic lift within the crease, from the inside, may be of use? Is that what these products might provide? Further, is it not slightly more dangerous to inject dermal fillers close to the eye?
Thank you for your recommendations.
First, I am not aware of any studies that prove that sleeping position creates or accelerates what you describe as symmetrical lower eyelid creases. Second, I agree that a surgical solution is not likely an appropriate answer to your problem. The range of options from Botox to injectable fillers may be useful. A local plastic surgeon can advise you about what are your best options.
