Initially there will be tiny pinpoint bleeding which will settle in a few minutes. You will experience a mild sunburnt sensation for about an hour after treatment, then virtually no discomfort.
The skin can be red for a few hours; this usually resolves within 24 hours, this is a normal sign that the skin is healing deeply. Swelling is minimal particularly under the eyes (if treated) and resolves in 1-2 days. Sometimes a small bruise can occur.
Other possible side effects will be discussed in your consultation with Dr Comins.
