Lip filler swelling is at its most significant on days one and two after treatment, then gradually reduces over the following week to ten days. The final result is typically visible at two weeks. Bruising, tenderness and firmness in the first few days are all normal.
Swelling after lip filler treatment is normal, expected and temporary. Understanding what is normal at each stage helps you interpret what you are seeing in the mirror without unnecessary concern, and helps you distinguish between the normal healing process and something that needs attention.
Day of Treatment
Immediately after lip filler treatment the lips will be swollen, often significantly. This can make the result look much larger than intended and different in shape to what was discussed at consultation. This is entirely normal. The swelling is a response to the injection process itself, not to the filler product, and it begins to reduce within hours.
Some bruising may be visible around the injection sites on the day of treatment. Mild tenderness and firmness throughout the lip area is expected. Avoid touching, rubbing or pressing on the lips.
Days One and Two
Swelling typically peaks on day one to two after treatment. The lips may look considerably fuller than intended and the shape may appear uneven due to asymmetric swelling. This is the stage most clients find most confronting, and it is the stage at which the result is least representative of the final outcome. Resist the urge to assess the result at this point.
Sleeping with your head slightly elevated and applying a cold compress gently for short periods can help manage swelling. Avoid hot food and drinks, exercise and alcohol for the first 24 to 48 hours.
Days Three to Five
Swelling begins to reduce meaningfully from day three onwards. The lips will start to look more natural in size and shape, though some swelling and firmness will remain. Any bruising that developed may be at its most visible during this period before it begins to fade. The lips may still feel tender to touch.
Days Six to Ten
By the end of the first week the majority of swelling has resolved for most clients. The lips begin to look closer to the intended result and the filler starts to feel less firm and more natural in the tissue. Some mild residual swelling or asymmetry may still be present, particularly in clients who bruise or swell more than average.
Two Weeks
At two weeks the result has fully settled for most clients. This is when the final outcome of treatment is accurately assessed. At Core Aesthetics, the review appointment is scheduled at this point so that Corey can assess the settled result and discuss whether any refinement is appropriate.
