Months ago I had a angineurotic edema, i'm 18 years old-and now I have wrinkles unde my eyes

At your young age, regardless of angioneurotic edema and swelling, you should not have wrinkles related to damaged skin or age. Botox is not a good treatment for lower eyelid wrinkles normally, in fact, it can make some worse.  If you happen to have coexistent skin allergies or dermatitis, you might have crepiness that can improve as the skin condition improves. It is quite common for patients with atopic eczema to have fine wrinkles under the eyes. See a dermatologist to determine what can be done to improve your skin, but avoid botox.

The lines you have described is likely the result of skin stretching from the swelling of angioedema. It should resolve on its own with time. I will not advice botox for this. The cause of your lines is self limiting, and botox is not the most effective treatment for lower lid wrinkles even in other instances. Laser resurfacing such as with Fraxel and or surgery would be a more efecetive treatment in instances of permanent lower eyelid wrinkles.

There are two kinds of wrinkles:  dynamic lines whereby muscle activity make the lines and in this case, Botox, which weakens muscles can help.  The other kind of wrinkle is static wrinkles, where they are present even at rest.  The lines you are describing are static lines, which means Botox won't help.  Your options are surgery (skin pinch blepharoplasty) versus resurfacing (either chemical peel or laser).  See an oculoplastic surgeon.
