Welcome to healthcare magic forum
Thank you for your query
i understand your concern regarding your skin problem
It is very difficult to comment only from description.
It look like folliculitis
, ingrown hair ,keratosis pilaris
or other follicular disease.
Some of the above conditions are resistant to treatment.
it may persist for long time and new lesion continue to develop.
You need to accept this first.
LASER or peeling may help you to some extent only.
In some case where we can not reach diagnosis ,skin biopsy
better to take opinion of other dermatologist
I hope I answered your query
