Take a shower and exoliate your skin with some scrub or loofa. (gets read of the excess dead skin and it helps the absorbtion of moisture later).
Draw a bath and pour in about 100 - 200 ml of good quality baby oil. Lay there for about 10 -15 min and relax.
When you get out, do not use a towel, just dry naturally.
Put some loose jammies on, go to bed and next day you should be very smooth.
After that, include in your daily skin therapy a rich shower gel (E 45, Dove Pro Age, those cream & oil shower gels etc ...) and try to use some good body cream for dry skin every evening. Repeat also the thing with exfoliation and oil bath about once a week.
You're skin will be as smooth as mine
just because I kinda do the same.
In case what you have is not just normal skin, but a sign of psoriasis, best thing is to see a doctor, as they'll can give you better creams and ointments that you can normally find in shops.
In regard to some lady minding your dry skin, I would not think anybody would mind. Even psoriasis is not contagious and most escorts see people with such skin condition, so dry skin is not a problem at all.
If you want to combine the cure with some pleasure, do go ocassionally to get an oily erotic massage.
