without a prescription????? If yes, can you PLEASE share the website you bought it from?
DHC also sells a powerful retinol cream that I love, called "Retino-A Essence". It's pricey, but it works wonders, especially when used in conjunction with some of the brand's other products. I know you're searching for Retin-A, but I've tried that stuff and it can be very harsh on your skin.
