Prevention magazine put the leading anti-aging beauty products to the test again this year and found seven products deserving of the “Defy Your Age” seal, including Olay ProX Age Repair Lotion, Neutrogena Norwegian Formula Age Shield Hand Cream and Estée Lauder Idealist Dual-Action Refinishing Treatment.

To determine the winners, Prevention enlisted seven leading dermatologists to test the claims of the 35 most promising products of the year on a group of 175 women, ages 40-plus, for a period of up to eight weeks. The doctors then employed state-of-the-art equipment to measure which products best delivered on their claims using before and after skin analysis. The teams investigated seven categories of products including hand, eye and night creams; lip, adult acne and microdermabrasion treatments; and day lotions with . This year’s winners are all available for less than $50.

Said Liz Vaccariello, SVP/editor-in-chief of Prevention, “A staggering number of beauty products are launched every year making it increasingly difficult for women to determine which ones they should invest in. We are proud to say that we put product claims to the test and found seven that truly deliver visible improvements—we saw wrinkles, brown spots and other over 40 skin issues disappear.”

Do you suffer from acne? Have you tried all acne skincare products available on the market and you see no results? Maybe you want to give the Meridian Acne Therapy System a go.

Dr. Nanette Liégeois-Creator of the Meridian Skin Care and
the Meridian Acne Therapy System.

Meridian Skin Care and The Meridian Acne Therapy System was created by Dr. Nanette Liégeois, an Harvard-trained and board-certified dermatologist. As an award-winning scientist, Dr. Liégeois began developing the Meridian Acne Therapy System after a detailed analysis of the best scientific data on acne treatment around the world. Her use of evidence-based medicine led to her discovery of Meridian’s unique dual-action formula that clears acne and conditions the skin with a combination of the most effective pharmaceutical and natural ingredients.

The Meridian Acne Therapy System is formulated to: Make your skin appear more youthful and radiant. Evens Skin tone. Gets rid of blemishes. Reduces redness and irritation. Prevents future breakouts. Rejuvenates your skin. Kills acne-causing bacteria. 

The Meridian Acne Therapy System is simple and easy to use. This is how to:

The 3 simple step Meridian Acne Therapy System.

Step 1: Meridian Gentle Cleanser – Wet the affected area with warm water. Gently squeeze a dime-sized amount of cleanser onto your fingertips. Using circular motions, gently squeeze the cleanser over the affected area. Avoid contact with eyes and lips. Rinse the cleansed area thoroughly after 30 seconds with plenty of warm water. Gently pat dry with a towel.

Step 2: Meridian Herbal Clarifier with Tea Tree Oil – Soak a cotton ball or pad with a small amount of toner. Gently wipe the cotton pad over the affected area, avoiding the eyes. Allow the area to dry for a few minutes.

Step 3: Meridian Fragrance-free Rejuvenating Moisturizer – (Optional, use as needed). Squeeze a pea-sized amount onto your fingertips. Apply the moisturizer sparingly. If you’re feeling dry, use a little more. With small circular motions, gently massage the moisturizer over the affected area. After the light moisturizer has been applied to your skin, allow the area to dry for a few minutes. This will avoid applying any excessive pressure to affected areas while the natural ingredients work their way into your skin.

Here are some facts about acne provided by the Meridian Skin Care: Acne, an inflammatory skin condition that may affect as many as 90% of us sometime in our lives, often starts with blackheads, the result of excess oil and dead cells that clog pores and attract bacteria.

What caused acne could be one of the following reasons: Hormonal changes often occur in teenagers and in women during their menstrual cycle. Heavy moisturizers can block pores, causing blackheads, whiteheads, pimples. Some topical anti-acne treatments can dry the skin, resulting in redness, irritation, the appearance of aging, and, paradoxically, more acne, as people try to moisturize their damaged irritated skin. Stress is thought to exacerbate hormonal changes and increased oil production.

About 30% of teenagers continue to cope with acne as adults. Other statistics indicate that from 20% to 50% of all adult women and 25% of all adult men will suffer from acne at some point in their lives
