What are Lip Fillers?

Lip fillers are injectable gels used in cosmetic procedures to improve lip volume, plump thin lips, and redefine lip lines and borders. The fillers also mask scars and inborn asymmetries. Hyaluronic acid, calcium hydroxylapatite, polylactic acid, and polyalkylimide are the most common types of lip fillers. 

How Long Does Swelling Last?

Swelling is the body’s natural response to inflammation. The extent of swelling differs from one client to another. After a lip filler injection, you may notice some slight swelling; after 24 hours, your lips will swell the most. The period after 48 hours will mark a significant decline in swelling. The swelling will gradually reduce and subside by the end of the first week. A swelling that lasts more than two weeks is uncommon; you should seek advice from your cosmetic doctor. 

How to Reduce Swelling after Lip Fillers

Ulakov et al. (2021) stated that anti-inflammatory creams like arnica can reduce swelling. When applying the cream, be gentle to avoid pressure on the lips.

Also, avoid spicy and salty food for a few hours; they could irritate the lips and cause itching. Activities like heavy exercises, places like saunas, pleasures like kissing, and practices like taking hot showers could also compromise the lip fillers if done before 48 hours; heat increases blood flow to the lips worsening the swelling. On the other hand, sweating and kissing may cause dehydration and bacterial infection. After lip fillers, limit your exercises to light activities like walking.
