Welcome to HealthcareMagic forum,
All brands are equally good .But results depends upon the strength used and duration used .There are 3 different strengths available (2,5 & 10).Even some of the companies have combination preparation available like with amenexil or tretinoin
.But there are no definitive reports as to which one is better.Every company claims his own theory.
One should use such lotions for atleast 6-10 months to get good response.Also at times one has to combine other medicines (vitamin & biotin
) along with.High protein diet with green leafy vegetables help in giving improvement.
