Tips to make myself look younger?

Not being overweight is one of the biggest ways someone can look younger. My 23 year old daughter is underweight, which isn't good, but people always think she is a teenager. Wearing light make up- a sheer foundation that gives you some color, mascara, lip gloss and a taupe eye shadow. Also taking very good care of your skin- exfoliate 2 or 3 times a week, wear a sunscreen and moisterizer and eat lots of healthy foods like yogurt, berries, carrots, salmon, nuts, and whole grains. I hope i have helped.

Babs gave you some good advise. I also have living proof of the basics.. Plenty of good clean mineral water, and lots and lots of fresh air, 8 hours of sleep a night, a minimum amount of stress, direct sun, and alcohol.

And whatever you do, don't smoke. : )

Someone told once that laughing adds years to our lives.. I like that idea too.

I agree with babs.  Too much weight makes you look older.  Lipstick is good because it makes your mouth look larger.  Healthy skin is very important.  Keep it clean, moisturized and free of heavy make up that will accentuate lines.  Also keep your hair styled in a fashion that looks good with your face shape, but also is up with the times.  What looked good on you when you were 15 is not going to look good on you today. 

Use a good cleanser, moisturiser, and get decent sleep. 

Do not pile on the makeup.
