Smoking Effects on Skin: What Cigarettes and Vaping Do to Your Face

Smoking affects skin in three main ways: it narrows blood vessels so less oxygen reaches the skin, it floods tissue with oxidative stress, and it switches on an enzyme that breaks down collagen. Over years that shows up as deeper wrinkles, lines around the mouth, a dull or sallow tone and slower healing. Vaping removes tar and carbon monoxide but still delivers nicotine, which narrows blood vessels on its own.

This guide covers how smoke damages skin, what doctors mean by "smoker's face," what is and isn't known about vaping, and what improves after you quit, with a realistic timeline. It isn't a lecture. If you smoke or vape, you already know the health case; this is about your skin specifically.

What are the effects of smoking on skin?

The effects of smoking on skin are faster aging, poorer circulation and slower repair. The American Academy of Dermatology (AAD) puts it bluntly: smoking greatly speeds up how quickly skin ages, causing wrinkles and a dull, sallow complexion. A review in the Journal of Dermatological Science concluded that laboratory and animal evidence indicates smoking accelerates skin aging, and that epidemiological studies point the same way.

DermNet, the dermatology reference run by New Zealand dermatologists, lists the mechanisms behind that:

The glycation link is the same collagen cross-linking process that sugar drives, explained in our guide to sugar, glycation and skin aging.

What is "smoker's face"?

"Smoker's face" is a cluster of facial features that doctors in one study could use to pick out long-term smokers by appearance alone. The term comes from a 1985 study in the British Medical Journal, in which patients at a general medical outpatient clinic were assessed against defined criteria. The researcher identified roughly half of current smokers who had smoked for 10 years or more by their facial features alone. The features were present in none of the non-smokers, and the association held after controlling for age, social class, sun exposure, weight change and lifetime cigarette consumption.

DermNet's description of how long-term smoking shows on the face includes:

• Facial wrinkles and furrows. Many people notice them first around the mouth, where repeated pursing on a cigarette and the heat DermNet mentions both act on the same small patch of skin.
• Baggy eyelids and a slack jawline.
• Dry, coarse skin, often with the dull, sallow tone the AAD describes.
• Gaunt skin: DermNet notes that the skin of a 40-year-old heavy smoker can resemble that of a non-smoking 70-year-old.

Not every smoker develops these, and plenty of non-smokers get lines around the mouth from sun, genetics and age. Smoking stacks the odds. Lines around the mouth tend to deepen with any repeated pursing, and lines from the nose to the corners of the mouth have their own causes, covered in smile lines and nasolabial folds.

Does smoking cause other skin problems?

Yes. Beyond aging, smoking worsens several skin conditions and raises the risk of some skin cancers. According to DermNet:

• Wound healing: smoking delays healing of skin injuries and surgical wounds and raises the risk of wound infection, graft or flap failure and tissue death. If you're planning any procedure, tell the doctor that you smoke or vape.
• Psoriasis: smokers tend to have more extensive and severe psoriasis.
• Hidradenitis suppurativa: smokers carry a greater burden of disease and respond less well to treatment.
• Skin cancer: smoking doubles the risk of squamous cell carcinoma, and 75% of oral and lip cancers occur in smokers.
• Staining: yellowing of fingers, fingernails and teeth.

If you have a sore on the lip or mouth that doesn't heal in a few weeks, or a scaly patch that bleeds or grows, see a doctor or dermatologist.

Does vaping affect skin?

Vaping is less harmful than smoking, but it still delivers nicotine, and nicotine affects skin on its own. The UK's National Health Service says e-cigarettes do not produce tar or carbon monoxide, two of the most harmful parts of tobacco smoke, and pose a small fraction of the risk of smoking. The same page adds that the long-term risks of vaping are not yet clear.

For skin, the key point is nicotine. DermNet notes that nicotine itself induces vasoconstriction, delays wound healing and accelerates skin aging, while also saying nicotine replacement is safer for the skin than smoking. We couldn't find long-term human studies that measure facial aging in people who only vape, so anyone claiming to know exactly what vaping does to your face over 20 years is guessing.

If you've switched from cigarettes to vaping, your skin is likely getting a better deal. Going nicotine-free is better still.

What happens to your skin after you quit smoking?

Circulation and oxygen delivery start improving within days, which is the foundation for better color and healing. Deep wrinkles and collagen loss that have already happened won't reverse on their own. The U.S. Centers for Disease Control and Prevention (CDC) lays out the general timeline, and the skin effects follow from it:

The CDC also notes that quitting reduces markers of inflammation and hypercoagulability. The skin column is a reasonable inference from what's known about circulation and nicotine, not a measured timeline. Individual results vary a lot with age, sun history and how long you smoked. A practical expectation: many people notice their skin looks less gray within the first weeks to months, while lines already etched in stay unless you treat them.

How can you repair skin after smoking?

Stop the ongoing damage, protect against sun, and use the few treatments with solid evidence for collagen. A simple plan:

1. Quit or cut down, with help if you want it. Nicotine replacement is safer for the skin than smoking. Your doctor or pharmacist can help you choose a patch, gum or other aid.
2. Wear broad-spectrum SPF 30 or higher every day. UV light also stimulates glycation in skin, so sun and smoke damage add up.
3. Add a retinoid at night. Retinoids are the best-studied topical treatment for photoaged skin; tretinoin is the most widely investigated. Start slowly with our retinol for beginners guide.
4. Moisturize daily. Dry, coarse skin is part of the smoker's-face picture, and a good moisturizer softens how lines look.
5. Ask a dermatologist about procedures for deep lines around the mouth if they bother you. Procedures heal better once you've stopped smoking.

How can a selfie scan help after you quit?

Changes after quitting are gradual, and it's easy to miss them in the mirror. A regular photo record makes them easier to see, which can be a real motivator. Pori, our iPhone app, turns a selfie into an overall skin score from 0 to 100 with a breakdown that includes Pigmentation & Tone and Anti-aging & Elasticity, plus a skin-age estimate, and its before/after comparison and progress charts let you line up a scan from your quit date against one from three or six months later.

An app is not a diagnosis: it reads how your skin looks, not what's happening underneath. It doesn't diagnose or check moles or sores, so see a dermatologist about any spot that bleeds, grows or won't heal.
