Cold compresses may be applied to reduce the swelling.
If the swelling is particularly prominent then anti-inflammatory medication such as ibuprofen can be taken (provided there is no contraindication to these medications with regards your medical history).
Crusting will develop, but it is important not to pick the crusts off as this may lead to infection and scarring.
Try your best to keep the area clean and dry and protect it with a broad-spectrum sunscreen.
Often more than one treatment is needed for optimum results and I will perform up to three treatments at six-week intervals if it is necessary to get the best results possible.
