Even if you're not a beauty buff, you've probably heard the word 'retinol' thrown around a lot recently. Editors, bloggers, and dermatologists swear by the stuff. But what is it, exactly? Should you use it? What's all the hype about? 

Essentially, retinol is a form of Vitamin A and it helps fight against aging skin, enhances collagen production, and prevents acne. Plus it can also help minimize any sun damage you may have incurred after several days at the beach this summer. 

If you're in your late 20s or early 30s, it's time to stock up on retinol and incorporate it into your daily skincare routine. But be careful - a little goes a long way and if used too much it can cause dry skin and irritation for sensitive skin. So definitely make sure to follow up with your favorite moisturizer.
