Skin changes since transplant

Ever since my kidney transplant in November, my skin has completely changed. I have always had dry skin. I have always used products for dry skin. For 2 months now, my skin has been oily. Thankfully, I haven't had any problems with acne like I did after my lung transplant (due to prednisone), but I think that's because I am using the Clarins skin care line. However, I am waking up with oil all over my nose and forehead. Even as a teenager, I never had this. I have read that oily skin ages slower than dry skin, so that's definitely a plus, but I used to could go 2 days without washing my hair, and now there is no way I could do that. My hair is oily too.

I am wondering if this has to do with diet changes. I mean, I went a year or more without eating much at all. Getting in one good meal a day was a chore. Now, I'm eating tons of protein, taking vitamins, and drinking tons of water. I'm also eating at least 6 meals a day.

Have any of you (post transplant or not) had such sudden skin changes?? I'm closing in on 40 pretty fast, so maybe age has a lot to do with it.

There is a college nearby that has an esthetician training program. They offer facials for $10 a pop and microdermabrasion for $50. I think it's usually $100 or more. I am thinking of taking my Christmas money and doing this. I do have some age spots that have recently (like in the past couple of years) shown up. I hear that microdermabrasion will help with those, and reduce the appearance of pores. My mother-in-law recently got a facial from them, and her skin looks incredible.
