If there exists the ultimate beauty tip it is this - Please don't just believe everything you read. Because like how you choose your skin care products, skin care reviews should also be based on your age.

20s Key Phrase: Skin Care Routine

The Roaring 20s didn't get its namesake for nothing. It was a time when people knew how to party. And party hard they did. This no tomorrow attitude remains to be true for people in their 20s, which is why they put little importance in their skin care. Needless to say, reading skin care reviews isn't very popular among this age group.

But even if your skin may feel invincible in your 20s, it's not as formidable as you think it is. Skin expert and writer of Beautiful Skin: Every Woman's Guide to Looking Her Best at Any Age, David Bank, MD, says that the bulk of sun damage on our skin happens even before you turn 18 years old. Worst, skin cell turnover becomes slower in your mid-20s and signs of aging also starts to become visible.

And, no, the answer isn't beauty products from the best skin care brands that cost an arm and a leg. Instead, the answer lies in having a dash of discipline to follow a skin care routine. Establishing one early on will have a great effect on your skin when you leave your 20s behind. Here are simple tips you can follow to build your routine:

• Don't forget to apply sunblock

• Don't go to bed with makeup on

• Apply moisturizer everyday

30s Keywords: Retinol and Retinoids

Once you're in your 30s, the first thing that you'll realize is that everything isn't how they used to be in your 20s. This includes, of course, your skin. At this age, reading skin care reviews has turned into mere casual reading to more of a habit. And don't be surprise if every review you read seems to be talking about you. Because your 30s is when you come face-to-face with all kinds of skin aging problems such as sagging, dryness, and wrinkles.

At this age, you have to amp up your skin care routine because your old one isn't just going to be enough anymore. Why? Because your skin cells are not renewing as fast as they use to be. To aid in hastening the process of cell turnover, you have to include the best skin care products to get younger looking skin.

Experts like Ranella Hirsch, M.D of the American Society of Cosmetic Dermatology and Aesthetic Surgery suggests looking for products that have retinol or retinoid as one of its ingredients. Not only does retinol help in skin cell regeneration, it also has properties that increase the amount of collagen in your skin, keeping your skin's elasticity. Put two and two together and you get great skin. Aside from applying retinol, other ways to rejuvenate skin cells are:

• Regular skin exfoliation

• Mild glycolic peel four times a month

• Eat more food that are rich in antioxidants such as berries, peanuts, peppers, and apricots

40s Keyword: Peptides

The big 4-0 turns you into a fervent skin care reviews reader almost overnight. At this age, you can rival professional market researchers in terms of finding the best skin care products. And even if you know that nature will always have its way, wouldn't it better that it takes its way more slowly? Or even, really, really slowly?

Wrinkles can be considered as the archenemy of any woman in her 40s. Once estrogen levels begin to drop, your skin tends to dry out faster which leads to dreaded wrinkles. Right now you should look for products with ingredients that induce collagen production such as peptides. According to research presented at the World Congress of Dermatology in Paris, peptides has a success rate of more than 50 percent in fighting wrinkles as compared to products that don't have it.

The most common type of peptides is called Matrixyl. It contains nourishing ingredients such as fatty acids and amino acids that goes directly to the deeper layers of your skin. Laboratory results show that Matrixyl can increase collagen production by more than 120 percent. This means 40 percent less chances that you'll get wrinkles.

• Grapeseed

• Food or products that contain Vitamin A

• Copper peptides that encourage elastin production
