I have dry skin but in winter it become more dried?

True for almost all: In the winter you need to limit the number of showers you take, limit the time in the shower and try not to use such hot water. You should only use soap in your private parts. Before you go to bed apply a moisturizer that is a cream not a lotion. A lotion can be used in the morning. If you are not going anywhere over a weekend the best thing you can do for your skin is to take a shower vacation.
