The longevity of results depends on the problem being managed:
a. Depending on the type of growth removed, rate of recurrence is variable. Skin tags, seborrheic keratosis and milia, when removed well, are largely permanent. Sebaceous hyperplasia and syringomas are more difficult to get rid off and tend to recur sooner.
b. Skin rejuvenation – The skin is a living organism that lives and dies; it is constantly being replaced from deeper down. As such, rejuvenative procedures have a time span and re-treatment every 4 to 12 weeks is recommended.
c. Acne scars – Acne scar treatment requires strong ablative powers. This results in more permanent collagen remodelling and resurfacing of scars. Results are largely permanent, and optimal results are seen after a series of 5 to 6 treatments, each spaced 1 to 2 months apart.
