If I quit smoking, will smoker's wrinkles "go away"?
Unfortunately, no. The damage that has been caused to the skin is not reversible even if the factor that caused it disappears. But you can treat smoker's wrinkles in other ways.
Do I have to smoke for many years to get smoker's wrinkles?
When one will develop smoker's wrinkles depends on many factors such as how many years one has been smoking, one's lifestyle, skin type, etc.
Can I combine anti-wrinkle treatments with each other?
Yes. Along with smoker's lines, you can also combine treatments for other areas of the face, such as for wrinkles in the middle of the forehead, for "crow's feet", etc.
