8.The mistake:
Not using moisturizer if your skin is oily.
If your skin is shiny or has an oily feel, it doesn't mean you should avoid moisturizing. After washing, your skin's relatively dry as a result of the cleansing process, explains Doughty. All cleansers, even water, take out some level of moisture. Using a moisturizer will replace this, protect your skin and prep it for makeup.
The solution:
Go with a moisturizer that won't add oil or a greasy feel, such as Oil-Free Oil of Olay.
9. The mistake:
Drying out the skin on your body.
Being in water that's too hot or staying in the bath or shower for too long won't hydrate your skin and can cause skin to lose vital ingredients that help to hold moisture in the skin, explains Dr. Shapiro.
The solution:
"Your bath or shower water should be warm enough to be comfortable, but not overly hot," says Dr. Shapiro. "All you need is a few minutes in the shower. In the bath, you don't want to stay in the water long enough to get that 'prune' effect." Set a time limit--around 15 minutes--max. Also, you should use a gentle cleanser, such as Neutrogena Rainbath Refreshing Shower and Body Gel.
10. The mistake:
Over-drying your skin in an attempt to control acne.
Using harsh soap can actually strip sebum from your skin, explains Dr. Brett Shulman, Clinical Assistant Professor of Dermatology, University of Rochester School of Medicine and Dentistry. "Sebum helps give skin its flexibility and pliability. Without this the skin can 'crack' and you can lose the skin's barrier function. This increases the risk of irritation and infection."
The solution: : Always use a mild cleanser or cleansing bar followed by a not-too-drying acne solution containing a low percentage of salicylic acid and benzoyl peroxide.
