Genetics do play a big role. If you’ve “always” had them or since a young age, you have probably inherited them. But other factors such as lack of sleep and lack of hydration will make them worse. Also, if you don’t wear sunglasses, your dark circles may actually be hyperpigmentation. Finally, as you age, the decrease in collagen under your thin skin will make the blood vessels more visible–hence making this area look darker.
While ROC does contain retinoids and AHAs, the two most important anti-wrinkle ingredients, it’s missing sodium hyaluronate, our favorite moisturizing ingredient. An easy work-around is to add a face moisturizer to your routine — preferably one that does contain sodium hyaluronate. (Both our top picks for best face moisturizer feature it, if you need a recommendation.)
Using this method, you can work out that higher SPF ratings don’t actually give you much more protection than medium SPF ratings. The Skin Cancer Foundation reports that SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97% and SPF 50 blocks 98%. While these differences seem insignificant, they can still make a great difference over time, especially if you have fair skin or a history of cancer.
