Skin Had Started Becoming Dry, Developing Some Red Spots. What Are Treatment Options?

Hello, I am a 33 yr old female. Since last few years , my face skin had started becoming dry and started developing some red spots. This doesn t seem to be something very major like no itching or pain but certainly not desirable as I had a very good skin texture some 6-7 yrs back. Since I don t use any cosmetics, I though they may go eventually by daily applying moisturizer and keeping a diet more of fruits & vegetables. I have long working hours and when even after an year of having a bowl of sprouts everyday & moisturizing my face, things didn t improve, I consulted a skin doctor. He said that the skin seems to be damaged by UV rays and prescribed applying Bihaku white lotion mixed with 3-4 drops of elocon drops and thereafter La Shield ( SPF 30) cream (after 10 minutes ) in the morning for 15 days. He also prescribed Sodox ( a multivitamin drug by Ranbaxy) for 15 days. This treatment worked and my skin started becoming softer in just 7-10 days. However, now its a month since I saw the doctor, and 15 days since the elocon lotion and sodox dosage are over, and again my skin has started becoming dry and spotty, they seem to be red rashes . My doctor s fee burnt a hole in my pocket the last time & this once, I will not be able to spare that amount. Please advice if I should start using elocon again or what is the best way to get my skin back and a regime which can follow without disturbing my work schedule.
