One of my biggest gripes about beauty regimes is that to be effective you have to hit it every single day without fail. I can't even remember to turn off the light to my closet half the time, how can I possibly remember to smear a dropper full of serum around my face and neck every damn night without fail? so I love the fact that SkinCeuticals Serum is supposed to suck into your dermal layer and fight free radicals for up to four days; if I go away for a weekend and whoops, it doesn't make it into the suitcase, no big thing.

Plus, this serum packs a loaded Vitamin C punch to sun damage and comes in three different graduated levels: a 10, 15 or 20 percent. Note: I have super-sensitive skin , and I found the 10 percent just right. This product is intended for prevention rather than reversal of age and environmental effects, so you won't notice a difference right away, but when you go to your high school reunion and people say you haven't aged a day, they might really mean it.
