Side effects are generally minimal.

You may notice some pinkness or redness to the skin immediately following the treatment but this typically subsides within 15-30 minutes. Skin may be slightly tender to the touch for a little time afterwards, but this is not always the case. If you are experiencing any sensitivity it can be treated with over the counter non-steroidal anti-inflammatory pain-killer medication.

Very rare risks reported include numbness, swelling (oedema), blistering, scarring, allergic reactions and nausea
