Hi!!!Vaseline is ofcourse a good remedy for dry skin
but since you are having red as well as blisters,hydrocortisone
is highly recommended.If you are not comfortable with fusidic acid
,go for Neosporin-H ointment,which can be applied in the sensitive areas of skin as well as those having sensitive skin.Hydrocortisone contained in Neosporin-H is a synthetic steroid
used as anti-inflammatory and anti-pruritic agent.
