The word you should have found is 'best'. The superlative refers to the top level. You therefore might be surprised that a search for the best wrinkle cream gives you thousands of results and many different answers when the superlative form should be a singular item.
'Best' should only give one result and in this case the best wrinkle cream, but as it doesn't you will need further information on the subject.
A good place is to ask a couple of questions, what are wrinkles and what causes them? These are the same questions being asked daily by the cosmetic industry giants around the world, leading to a very lucrative marking in anti-aging products for them and leaving most of the rest of us with almost too much choice.
Wrinkles are caused when we grow old. Also, external factors like exposure to the harmful rays (ultra-violet A and ultra-violet B) of the sun, excessive mental pressure (which leads to tension and headaches) etc also contribute effectively to the growth of wrinkles. Wrinkles destroy the beauty of our face. Hence, proper care should be taken while selecting the best wrinkle cream.
Technological advancement has resulted in the development of high quality anti aging skin care products. Some of these are developed after years of research. The worldwide demand for a cure to wrinkles has fueled the need for extensive research into developing a wrinkle cream which would permanently make those ugly wrinkles disappear.
After all this, how do you pick the best? The answer is not straight forward, you need to do your research and find our your skin type as well. Your skin will not respond to a wrinkle cream the same as the next person, everyone is different. What is right for them, might not be right for you.
A good move would be to get advice from a specialist such as a dermatologist. Their advice can help to put you on the right track to finding the best wrinkle cream.
