Go to your local drugstores, get free samples of skincare products and give them a try. While certain special treatments are more expensive, even in this area you can get good results for less.
I've been using Clarins men, Zirh and Anthony Logistics products for several years now and am happy with the results.
To cleanse I use the Anthony glycolic cleanser (on most days), Zirh Scrub or Anthony scrub (about once a week) and Anthony face mask (once every two weeks or so)
To moisturize, the Clarins gel and Anthony all-purpose moisturizer (usually at night). And for eye care, the Clarins serum, which is excellent. Each one of these products in regular size lasts me more than a year. Besides I don't use toner, lip balm, concealers or self-tanning products, so I am able to keep grooming expenses in check.
