The upshot: We may be able to get away with using the same cream on our neck as we do on our face — if our complexions tend to stay bone dry and don't tolerate particularly strong actives, that is. "Because the skin [on the neck] is delicate, you may not be able to tolerate some of the more irritating anti-aging topicals that you can use on your facial skin. For example, you may need to use a milder retinoid on the neck and chest than on your face," Dr. King says.
