Whilst we all get wrinkes there's no harm in helping to delay their onset or in minimising their appearance - yes there's more important things to worry about, but you can say that about nail extensions, fake tans & about any other beauty treatment & we'd all be out of a job. We only get one skin, and it does suprise me that people will abuse their skin which is irreplaceable but wouldn't dream on polishing their furniture with surgical spirit, which is replaceable! It also suprises me how many people think it's vain to look after your appearance but that it's essential to look after one's house & possessions!
Wrinkles can have many causative factors, and are often indicators of underlying dehydration, dryness, UV damage, glycation and various other issues, deal with this & you'll reduce the wrinkles appearance & delay the onset of others. To be honest without seeing your skin it's impossible to say what's needed so the best bet is to get to a therapist who understands skin & it's funtions and ask them for face-to-face advice.
