My doctor told me I needed to start looking into my skin care but i dont know where to start.
I can give you some tips. Firstly, skin care deals with many things that enhance the skins appearance. 
What is good for treatment of the skin?
The most important thing you can do first is your nutrition, and avoiding sun exposure. How's your diet?
I diet pretty good I think it might be the sun thing since im outside a lot
Yeah. Besides those two, you can use cosmetics, botulinum, and exfoliation techniques that help the skin in different ways.
O so should I invest in a good lotion?
Yes absolutely. Have a look online on popular forums. You will find some good advise if your skin is too dry or too moist. It will prevent dermatitis and skin injuries. But what you sue depends on your skin type.
Ok sounds good im going to start working on it tonite.
There are some more extreme interventions like medications, which will treat, cure or prevent specific skin diseases. Like some acne medications.
