Does anti wrinkle cream work
The straight answer is that it depends entirely on what you were expecting, and most disappointment with these products comes from an expectation the label quietly encouraged.
If you expected a wrinkle to go
It will not. A cream or serum works on the surface, and a set wrinkle is not a surface feature. No product sold over the counter takes one out, and any page suggesting otherwise is the page to walk away from.
If you expected skin to look better
That part is real and ordinary. Skin that is properly hydrated looks fuller, reads smoother and catches light more evenly, and fine lines look softer in it. Most people can see the difference and it is worth having. It is a change in how skin looks, held up by continuing to use the product.
How long before you can tell
The hydration part shows up quickly, within days, because it is about the state of the surface rather than a slow change. If several weeks of nightly use have left you unable to tell any difference at all, that is your answer and the product is not for you.
Judge it against the honest promise
Decide what the product actually claimed before you decide whether it worked. Something that promised smoother looking, better hydrated skin and delivered it did its job. Something that promised to erase years never had a chance of keeping that, and the failure was in the claim rather than the bottle.
The cheapest thing that works
Daily sunscreen, which is not marketed as anti wrinkle and outperforms everything that is. It is a strange fact about this category and it is worth acting on.
