A word of caution:
If it is extremely cold outside I wouldn't apply aloe vera gel right before going outside. Since aloe gel penetrates through all seven layers of your skin and is extremely moisturizing it can cause freezer burns. Wait at least one hour. Or wait until you are inside for a long time before treating your face with aloe vera gel. Once the temperatures are above freezing it is ok to apply aloe vera gel onto your face right before going outside.
