Generally, non-surgical facelifts have zero to minimal side effects unlike the conventional facelift. Only a few individuals reported having side effects that are not really permanent. This could include minor swelling, redness, itchiness, and warm sensations. However, these symptoms can be alleviated with proper aftercare.
In most cases, individuals find relief from these issues after a few days. They usually require no other treatment, they resolve on their own. It is important to understand that the maximum results of the procedure may take 8 or more months to be visible. While the process takes place, always follow proper aftercare as prescribed by your cosmetic doctor. If the issues persist or get worst, report it to your doctor right away to avoid further complications.
