Deciding whether to dissolve lip filler before undergoing lip surgery depends on several factors.

If your filler is over six months old and hasn't migrated, it might be worth keeping—especially if it enhances your lip volume naturally.

However, if the filler has migrated into the upper lip or if your lips are overly large and conceal your teeth, dissolving the filler may be necessary.

Ultimately, the decision is case-specific and should be made with your surgeon’s guidance.
