The Ordinary Argireline Solution 10%

What are your experience with the The Ordinary Argireline Solution 10%? Was it effective for wrinkle improvement? A waste of time and effort? An HG? I’d love to hear your thoughts. I’ve just been using this for a couple of months and don’t really know if it works. I don’t have forehead lines but I do have the shadow of the number 11 between brows. Don’t have crows feet too but have saggy lids. I am using tretinoin so I guess the argireline wouldn’t do much for me. ... but this product gives me temporary relief from headaches. I often suffer from terrible headaches and any relief is great for me. I hope overusing this stuff isn’t bad because I use a lot. I mean it helps with wrinkles AND headache so might as well use it rather than take tylenol pills.
