Unless you have been living under a rock, you must have heard about retinol. Surprisingly, even though most of us have heard of it, we don’t really know much about it. Is it for ati-aging? Is it for acne? Is it safe? Basically, retinol is derived from vitamin A. It is supposed to be excellent for preventing wrinkles. It is also great for unclogging pores, boosting collagen, and speeding up cell turn over. It helps to plump fine lines and remove discoloration. It also works pretty fast, and can show results in as little as one month. Even celebrities use retinol.
