Scientists have studied these ingredients again and again, from AHAs, antioxidants, collagens, extracts to other unique, sometimes gross ingredients. Some ingredients actually help in improving the appearance of the skin. However, even if we can basically find a glossary of scientifically analyzed products, still, a massive number of ingredients have not been tested for any proof. Here are some common and well researched ingredients on anti aging skincare lines:
This is a form of Vitamin A and is considered an antioxidant which was the very first one to be used for OTC skincare products. As an antioxidant, retinol neutralizes the presence of free radicals. This ingredient is not as potent as tretinoin, another derivative of vitamin A and that is why it was accepted for commercial use since it is not as intense and not as harmful as the latter one, a prescription product that is used sparingly.
Your Alpha, Beta and Poly hydroxy acids come from fruits. They are considered as exfoliants and therefore, they are used for chemical peels. They strip off the dead skin cells and allow new, fresh skin to regenerate, giving the appearance of more healthy, younger skin. However, a problem is that you are more photosensitive every time you use these products so it is necessary to wear sun protection.
So what is effective?
It varies, really to the products. Not all expensive creams offer the most effective skin care results. It is necessary to look at the latest research and find out if their claims for their product are based on actual studies. If there are no supporting studies, you might want to put a little question mark on them. Be wary that expensive, OTC creams are offered in lower doses to follow regulations so you might be spending more than you should.
