The time of year that you shop for a daily facial moisturizer can influence what type you should buy. When the weather turns warm, it may be time to lighten up on your daily skin care routine. With a more humid atmosphere and increased perspiration, thick moisturizers may trigger seasonal breakouts. If your skin suddenly seems like an oil rig, consider switching to a lighter, non-greasy formula. Chilly winter air calls for greater facial skin protection. Unless you have particularly oily skin, a richer lotion may be necessary to prevent the face from drying out. When applying cold weather lotion, also pay attention to areas around the lips and eyes that are particularly prone to winter skin damage.
