Greetings! RF ablation or preferable - CO2 laser ablation can be done with reasonably good results. In some patients mild recurrences may be seen. But most importantly you need to understand - that these are normal - and do not necessarily need to be treated - so you shouldn't be losing your sleep over it / u r perfectly normal if u have these spots. For further evaluation - see a qualified dermatologist near you. Warm regards, Dr Govind Suresh Mittal. Bengaluru.
