Just my two cents but retin a is the holy grail of anti aging. MY derm told me its 20x more effective and stronger than otc retinol and yes, i have been using it prescribed for years. So,if you look at how much the otc retinol costs or other supposed anti aging creams cost as well, the price seems worth it for the real deal. I am fortunate enough to have insurance that covers it for me and yes, i only pay $10 a tube but if you can get it cheaper elsewhere, like where these ladies told you, go for it.
