When we talk of anti aging products, there are already so many different ones in the market today that it is oftentimes difficult to identify which ones actually work. A good way to determine the best anti aging product is for you to acquaint yourself with the ingredients used in anti aging products.

The top anti aging products in the market today should contain ingredients such as Alpha-Hydroxy Acids (AHA), antioxidants, collagen and Vitamins C, D, E and K.

Alpha-Hydroxy Acids or its substitute Beta-Hydroxy Salicylic Acid (BHA) clears your skin of any dead skin cells by exfoliating the skin's surface. The lesser dead skin cells are accumulated on the pores, the fresher, cleaner and the more youthful your skin appears. Albeit alpha-hydroxy acids and beta-hydroxy salicylic acids are widely used in anti aging products, some individuals experience irritation due to the ingredient's exfoliating ability on the skin.

Other ingredients like antioxidants work more than just on the surface. The antioxidant Coenzyme Q10 encourages cell turnover by restoring and preventing damaged skin. This also gets rid of dead skin cells that cause discoloration.

Collagen is another anti aging property that moisturizes the skin and protects it from further damage from too much sunshine or too much dryness. Collagen is also responsible for plumping the skin.

Most anti aging products these days already have added vitamins. These are Vitamins C, D, E and K which are essential in protecting the skin from deficiencies, as well as in healing wounds, smoothing scars and strengthening the immune system. Several vitamins are antioxidants which fight against free radicals in the body.

Some ingredients work while there are also some that still has to be proven to work. Vitamin C is one example of this ingredient. It is yet still to be scientifically proven if Vitamin C can truly prevent anti aging or that it has any relation to skin care. This is probably the reason why some Vitamin C creams do not have lasting effects when used as an anti aging product.

It is by far antioxidants that make the best anti aging product work. It has been observed that a formula without these essential ingredients just wouldn't be effective. Free radicals are naturally produced in the body, but its release of unstable oxygen can damage healthy cells. As it has been observed, free radicals are the culprit when it comes to age-related problems. Antioxidants help keep free radicals at bay, thus delaying the aging process.

Estrogen, testosterone, progesterone, DHEA, thyroid and melatonin are also essential anti aging hormone supplements that are known to delay aging, increase libido, improve erratic sleeping patterns, prevent cancer and help protect the immune system.

Other essential anti aging properties include Human chorionic gonadotropin (hCG), oxytocin, erythropoietin (EPO) and insulin. These ingredients are known to be effective up to some extent. Human chorionic gonadotropin aids fertility in humans; oxytocin strengthens the reproductive system. Erythropoietin deals with anemia while insulin is used to stabilize diabetes mellitus type 1.

Supplements can have varying effects on different individuals. Therefore it is crucial to see a doctor before using anti aging products containing any of these.
