Yes, remarkably so. Besides not smelling like an ashtray, your nails will grow free of discoloration, your skin will tighten and lose some of the leathery appearance it has now (or will eventually develop), and your color will improve—causing you to appear more youthful. And it happens fast.
Your brownish, discolored skin will be replaced by healthy, new skin in 3–4 weeks. A well-documented study showed that after just 9 months, skin aging (your appearance) was reversed by a full decade. Quitting smoking is like having a facelift and getting paid for it.
Your fingernails will start to replace tar-stained nails with healthy new nails in a few weeks. They’ll be fully replaced by healthy, new nails in 3–6 months.
You’ll also have better breath, cleaner teeth, fewer gum issues, and quitting smoking will lower your risk of tooth loss. In other words, your teeth will stay in your mouth where they belong.
