Thing is it does work but it also depends what y get. If y got dry skin, consistently hydrating ur skin with high quality moisturiser will make it nice and soft and not dry. Caffeine serum under eyes will remove thst eyebag look and rejuvenate. Its just science. Only thing like anytbing else its temporary. You cant just stop but skin is juat like anytbing else on your body. More nourishment more healthy. (I do alot of skincare as a model and from past experiences w exes who use shit tonne and have flawless skin. But u can also just be genetically lucky and not need it like things wont effect your skin as it would the average person. 1 thing you should always use tho even if u got the best genes is sunscreen! Sorry I be yapping
