Swelling and bruising from Ultherapy can last up to 2 weeks. There is a considerable amount of trauma that occurs deep in the tissues, so bruising and swelling is normal. This trauma is safe & it is what causes the collagen stimulation and strengthening in the tissues. The swelling and bruising can definitely be more noticeable or extreme in some people, dependent on many factors, such as: were any blood thinners taken before the treatment, how thin the skin is, how much facial fat there is, and if the individual performed excessive physical activity within a day or two after (this can contribute to more bruising and swelling), among other considerations.Thank you.
