In order to maintain optimal results from lip augmentation with fillers, it is recommended you avoid activities such as smoking and excessive sun exposure for at least 48 hours post-treatment. Use specialized skincare products formulated for use after injectable treatments, including sunscreen with an SPF of 30 or higher. Facial moisturizers containing ingredients like vitamins C and E help protect against free radical damage. Avoid harsher exfoliants like scrubs or retinol products until healing has been completed entirely, typically in about one week’s time. Regular maintenance visits every six months may also help extend results.
