I'm in my early 20s -- my skin is usually normal, but I have some problems with enlarged pores, breakouts, redness and oiliness. Most repair serums leave my skin too greasy, even when left to soak in overnight. This is a great "starter serum" for younger skin, when you aren't worried as much about correcting signs of aging as you are about preventing them. It's a great light moisturizer (I apply it daily after exfoliating, cleansing and toning) which balances and smooths my skin. Depending on the day, I follow it up with a gel moisturizer if I feel like I need it, and a heavier cream around my eyes. Will likely continue to buy for the next few years. This is a great deal for the price, and a perfect size for traveling.
