To stay on-trend but not overdone, pick one item from a particular trend -- say, metallic eye shadow or glitzy lips -- and
never wear more than one trend on your face at a time.
In your 40's, toss away your cakey face powder. This is the decade when skin is really dry and most powders will dry it further and accentuate fine lines and wrinkles. If you must use powder to tame oily areas, choose one that is finely milled and apply it sparingly, using a brush instead of a puff.
For women in their 50s, less is definitely more. You want to minimize the amount of product you put on your face. Foundations should be lighter and applied only where you need it; avoid powders; and don't overdo it on the eye makeup. Bypass heavy eye shadow altogether. Instead, smudge a soft pencil liner in charcoal gray or soft brown close to the edge of your upper lid. Then use mascara only on the upper lashes. For the biggest boost, use an eyelash curler. It's like giving yourself a temporary eye lift. If you haven't used one since your 20s or 30s, now is time to use it again.
Makeup tips for the 60 + : If you're not ready to go under the knife, or simply want to accept the aging process with grace, makeup can help. The key is to keep your look simple. The biggest makeup mistake older women make is wearing too much eye make-up -- and still trying to find and darken the crease in the eye socket. By the time you reach 60, the only way you're going to find that crease is with the help of a good surgeon. So instead, just use a soft pencil to smudge some color near the lid and leave the crease alone. Go easy on foundation and wear a pink-toned blush and moisturizing lipstick. If you want to color your hair, go lighter, not darker. And never darken your brows.
Going darker with hair or brow color is a big mistake. It creates a harsh look that emphasizes lines and wrinkles.
The best advice for all women is to let your natural beauty shine and "be strong and be confident!"
