You are 35, but people put you at 42. The lines at the corners of your lips deepen, your eyelids droop, your complexion turns a tired grey. The cigarette plays a part — and science has measured it, with photos to back it up.

What exactly is the 'smoker's face'?

The phrase was coined in 1985 by US dermatologist Douglas Model, who described a fairly precise cluster of signs: deep wrinkles around eyes and mouth, thin greyish skin, prominent cheekbones, hollow cheeks, drooping eyelids.

Today dermatologists prefer to talk about extrinsic skin ageing — the kind caused by environment, as opposed to intrinsic ageing (genes, time passing). Tobacco plays in the same league as the sun, and sometimes harder.

Three mechanisms that explain everything

1. Collagen melts away

Collagen is your skin's scaffolding: it gives firmness and bounce. Cigarette smoke does two things at once — it slows the production of new collagen, and it activates enzymes (matrix metalloproteinases, or MMPs) that destroy what is already there. Double penalty.

2. Your blood vessels tighten up

Nicotine constricts the small vessels feeding the skin. Result: less oxygen, less nutrients, fewer vitamins reaching the cells. That is why complexion turns grey or yellowish — the skin is literally underfed.

3. A storm of free radicals with every puff

Each puff dumps tens of thousands of unstable molecules into your body, attacking cells. This chronic oxidative stress damages DNA, accelerates faulty cell renewal, and depletes vitamin C from your skin — exactly the vitamin you need to make collagen.

The twin study that does not lie

In 2013, a US team used the 'Twin Days Festival' in Twinsburg, Ohio, to photograph 79 pairs of identical twins in which one smoked more than the other. Same genes, same parents, same genetic baggage — the only difference was the cigarette.

Verdict from the plastic surgeons (who did not know who smoked what): the smoking twins had more drooping eyelids, more under-eye bags, more lines around the mouth, deeper nasolabial folds (the lines between nose and corner of the lips) and looser jaw lines. None of which alcohol, sun or stress could explain — researchers checked.

What happens when you quit?

Good news: quitting kicks off real repair, faster than you would think.

1. A few days oxygen returns to the blood, complexion starts firming up.
2. 2 to 4 weeks natural glow comes back, skin is less dry, dark circles fade.
3. 2 to 3 months microcirculation restores, healing improves clearly.
4. 6 to 12 months collagen production really restarts.
5. Several years light wrinkles soften; deep ones stay.

How to maximise recovery
