Deep Creases Under Eyes After Botox for Crows Feet

Creases near the eyelids are related to both the eyelid muscles and smile muscles. When the eyelid muscles are treated with Botox, there are less Crow's feet but the smile muscles may be trying harder to make expressions once the contribution from the eyelid muscles are less. The lower eyelid skin may be bunched up more when the smile muscles work harder. The smile muscles should not be treated as that can cause a distrubing asymmetry or functional problem with eating, drinking and smiling.Rarely one or two units of Botox can be injected by an expert in the lower eyelid skin but the condition of the patient's muscle tone and preoperative swelling condition must be taken into account. There can be an exacerbation of lower eyelid puffiness and a droop of the lower eyelid which can worsen a dry eye situation. This would be an off-label use of Botox and may not help the situation.

Botulinum Toxin (Dysport or Botox) will relax wrinkels caused by muscle contraction but does not tighten lax skin
 

I agree that you can get a compensatory reaction from other muscle groups after Botox injection.  More botox will not resolve this particular issue.  I also see many cases when correcting one area of wrinkles makes untreated areas of wrinkles stand out when they weren't so noticeable before undergoing treatment with Botox.  If your physician took pre-treatment photos they could help you appreciate the before and after effects and you may find out that the "new" lower eyelid creases may very well have been there before the treatment.  In which case, you could consider a lower lid blepharoplasty as a treatment option.
