While the majority of patients who buy Vaniqa online frequently report no side effects, there are some potential complications. The most common problem is a skin issue which may be present in the following forms: tingling, burning, stinging, a rash, or temporary redness of the treatment area. Also, folliculitis, or hair bumps, may be present. A patient who experiences these adverse reactions should reduce the use of the cream to only once per day. If the conditions are persistent or pronounced, your local doctor should be contacted for professional advice.
