To keep your face looking as youthful as possible, you need to properly cleanse, exfoliate and moisturize your skin while never leaving the house without at least 30 SPF sunscreen. I've dubbed this process "The Basic 4-Step Skincare Regimen," which I outline in this article. But before we go there, how you care for your skin is utterly dependent on the type of skin you have: oily, normal/combination, dry, sensitive or sun- damaged.

Be careful not to cleanse too often, you risk over-cleansing skin, see signs you are overcleansing your skin. You really only need to wash your face at night to remove makeup and sunscreen, which can clog pores. If you have dry skin, consider cold cream like Pond's, which the French use. Simply apply cream, then wipe off, no water needed (if you have hard water, it can be especially harsh on skin). Most women prefer the water method: Use warm water to loosen dirt and clogged pores. Use a dime-sized bit of cleanser, then rinse with cool or lukewarm water. I personally swear by my Clarisonic Mia, as does pretty much everyone I know who has one.

While I know of at least one famous beauty editor who swore skin doesn't need moisturizer, basically everyone else I've read disagrees and is an adamant believer in it. A basic rule of beauty is that if you have dry skin, you should invest in a basic moisturizer. So how much should you moisturize? Your skin will tell you. When your skin is tight, it's crying out for moisture. Be careful not to over-moisturize -- this can clog pores.
 cause of wrinkles is sun damage, so it's important to use a sunscreen of at least 30 SPF from your early years on even in winter and on cloudy days. A great trick is to purchase two moisturizers: One for night and one for day that includes UV protection. Don't use moisturizers with sunscreen at night, the ingredients are not meant to be used 27/7 and can aggravate skin. When choosing a sunscreen, make sure it contains Mexoryl (found in my favorite sunscreen La-Roche Posay) or Helioplex, found in Neutrogena products.
