My face feels really dry, I've tried loads of products, Clinique, L'Oreal, Body Shop but after about a week, my skin feels horrible and tight. I don't have time for cleansing and toning, so does anyone know of a great facewash?

Its nice that you are applying all this stuff to your face, how are you feeding your skin in general?

Water is one of the most important - if you are not drinking enough water (or liquids low in sugars and caffine) then you most likely are dehydrated.

Fats are essential - if you eat a low fat diet or the 'bad' fats more than the 'good' fats then the result is dry skin.

Foods and the helpful minerals/vitamins:

1. Foods that contain omega-3 fatty acids: salmon, flaxseed, tuna, avocado, nuts
2. Foods that contain zinc: oysters, crab, beef, and beans. Zinc helps heal wounds.
3. Foods rich in sulfur: garlic, onions, and eggs. They help to keep your skin smooth.
4. Water.
5. Avoid caffeine and alcohol. These diuretics will suck your skin dry.

Also a multivitamin one a day type.

To treat and sooth the skin while you are feeding it use an aloe and/or vitamin E moisturizer - preferably one with out mineral oil (petroleum oil) in it.

If this is a recent change and there has been no change in your diet, or where you live/work spend your day - then see a doctor - there are several conditions and illnesses which manifest a symptom of dry skin.

if you have dry skin and dont have problem with oil or large pores or pimples....then don't focus so much on cleansing...focus on moisture....get a cleanser for mature skin, it doesn't strip the oils. Some people use oatmeal....just oatmeal mixed with water....try Neutrogena products, I'm sure you'll find one you like.
I like pure glycerin for moisture, its about 3 bucks a bottle at cvs. Neutrogena's oil free intense moisutizer is my favorite. Try Alpha Hydrox products also, you can find them at Drugstore.com, I've heard great things about the cleanser.
