Most wrinkle creams simply hydrate skin, plumping them out and making them look temporarily better. So don’t buy into the hype.
There is one product that has a solid history and reputation for reversing fine lines, however, and that is Tretinoin (Retin A)
Tretinoin creams or drops penetrate the skin and increase skin cell turnover.
Studies have shown them to be effective at treating acne, reducing fine lines and wrinkles, and reversing the effects of photoaging, or sun damage. The ultimate results are related to the markedly increased collagen production.
Although our own internal Vitamin A (retinol) does stimulate collagen production but when applied externally on your skin it’s absorption is minimal and further conversion to collagen-stimulating tretinoin is nearly undetectable.
