The cold and snowy weather continues to cause problems for my Retin A treated skin. Apparently it is the low humidity in the air that’s driving the red patches, tightness and flaking. I’m going to cut back Retin A useage to 2-3x per week and drench my skin with a heavy moisturizer in the morning and evening. In addition I’m going to address environmental humidity both inside and outside. At night I’m going to plug in my humidifier to compensate for radiator dry air. To humidify myself I’m going to try to remember to drink at least a quart of water a day. In warm weather I seem to have a glass of ice tea surgically attached to my hand. When it gets cold, my daily liquid intake drops to several cups of tea and coffee.
