2.4 Contraindications and side effects
The following contraindications and side effects are the res-
ults of a thorough analysis of the professional clinical literat-
ure concerning microneedle treatment. If the person re-

2.4.2 Side effects
In order to avoid unnecessary side effects:
Find out the patient's medical history and possible previ-
O
ous surgical procedures before the treatment.
Ensure that patients with a herpes simplex virus infec-
O
tion have been treated beforehand with a prophylactic
antiviral therapy.
Complications during and after a microneedling treatment
seldom occur in comparison to alternative methods of scar
treatment and are generally minor. In most cases, this is loc-
alised bleeding in the area of the treated skin. In some
cases, minor side effects may also arise. The following side
effects are reported in the professional clinical literature.
Frequent:
Pain and discomfort on the first day after the treatment
O
Short-term inflammatory reactions, erythema and/or
O
oedema up to 6 days after the treatment
Skin irritations (e.g. itching or increased temperature),
O
which normally subside during the first 12 to 72 hours
after the treatment
Formation of scabs, which normally recede in the first 5
O
days
Temporary peeling of the skin which normally subsides
O
within 8 days
Seldom:
Formation of herpes simplex virus type I (HSV-I) blisters
O
Formation of small pustules or milia as a result of inad-
O
equate cleaning of the skin prior to treatment
Hyperpigmentation with the body's own pigments, in par-
O
ticular with darker skin types, but completely cleared up
within a few weeks
Inflammatory reactions, haematoma, erythema and oed-
O
ema
Retinoid reaction (from slight reddening to peeling of the
O
skin)
As a matter of principle, recently treated skin areas should
be protected from UV and solar radiation.
