If you have a tan you should wait at least 4 weeks after your last UV exposure until there is no activity in the pigment producing cells.
You should avoid perfumes, deodorants or any potential irritants in the treatment area before and after treatment.
You should avoid alcohol, aspirin and non-steroidal anti-inflammatories such as Nurofen for 48 hours before treatment - this will reduce the risk of a skin reaction.
