The basic idea of eye cream ingredients is look for darkness-inhibiting, and take time to mull over the type and potency of the effective ingredients. Some ingredients may have only temporary firming factors, while sum actually promote healthier skin.

The common firming ingredients found in these eye creams are caffeine, alcohol, retinol, alpha-hydroxy acids, copper, and vitamin C. Now, which one really works, why are the others actually in your product? Well, caffeine and alcohol, when applied on the skin, temporarily dehydrates it, thus, making it look better. Most day creams contain these products for the temporary fresh day-look you are looking for. Retinol, alpha-hydrosy acids, copper, and vitamin C are the ones that work under your skin, promoting the growth of collagen. These are mostly found in the night creams for repair.

As for the darkness-inhibiting ingredients, they are vitamin K, kojic acid, and hydroquinone. These are the ones to use if your major problem is the dark circles around the eyes. Vitamin K inhibits bruising. When the skin is bruised, although it has no visible marks, leave dark spots, so anything that slows it down is good. The other ingredients Kojic acid and hydroquinone are popular ingredients for skin-whitening products. They lighten the skin, but make sure it does not have too much of these two, since if applied in the wrong dosage, can also cause burning and darkening.
