When Will Bruising Go Away After Restylane Injections in Tear Trough?

It is unusual to have bruising that persists beyond a few weeks,  I recommend you return to your physician for an evaluation. 

Bruising after restylane injection into the tear trough region is fairly common. Seven weeks of bruising is not.

Bruising is very common after fillers injections, especially under eyes. It may take up to a week or two to resolve. Vitamin K cream can be helpful in moving things along.

Bruising is common after filler injections under the eyes. It will resolve but may take a week to 2 weeks at times depending how your body absorbs it.  The color of your skin will not affect the healing of the bruising however, you may have some pigment change in the area which can look like bruising.  I would have your doctor evaluate the area.  You may need a bleaching cream to help lighten the skin.  - Dr. Monica Halem

The skin under the eyes is extremely thin and prone to bruising. I recommend that patients who often bruise take Arnica pills for a few days before a Restylane injection here, and continue taking the pills for a few days after. You can also apply Arnica cream after the treatment to help with bruising. Some bruising and swelling can last for a few weeks on certain patients, but it should continue to get better and resolve over time.
