Dermatology research has not yet confirmed a direct causal link between vaping and acne, but a growing body of evidence (including a 2024 systematic review in the Archives of Dermatological Research) shows that vaping contributes to and worsens breakouts through several distinct pathways. The most consistent dermatological observation is that vapers report more frequent acne breakouts than non-vapers, particularly in a characteristic pattern around the mouth, chin and lower face.

The four main mechanisms are: nicotine vasoconstriction (reducing blood flow to skin, slowing healing), PG and VG dehydration (drawing moisture from skin, prompting compensatory oil production), hormonal effects (nicotine raises cortisol, which affects sebum and can trigger cystic acne), and direct vapour exposure on the skin around the mouth (deposition of vape aerosol residue can clog pores in that specific area).

For people who already have acne or are acne-prone, vaping typically makes the condition worse rather than starting it from nothing. Existing breakouts last longer because reduced blood flow slows healing, and scarring is more likely. For people switching from smoking to vaping, the skin usually improves significantly because vaping eliminates the much heavier oxidative load of cigarette smoke. NHS dermatology advice remains: if acne is bothering you, talk to your GP; they can refer you to a dermatologist on the NHS or prescribe topical treatments directly.

Why perioral acne (around the mouth) is the typical pattern

Three reasons concentrate vape-related acne around the mouth and chin. First, direct exposure: vape aerosol deposits microscopic droplets of e-liquid residue on the skin around the mouthpiece, which can clog pores in that specific area. Second, dehydration: PG draws moisture from the skin near the mouth more than skin further away from the vape, prompting that area to overproduce sebum. Third, hand-to-mouth behaviour: regular vape users touch their face near the mouth more than non-vapers, transferring bacteria from hands. The result is a fairly characteristic perioral and chin pattern that dermatologists in NHS clinics increasingly recognise.

What the 2024 systematic review found

The 2024 systematic review of electronic cigarettes and skin health, published in the Archives of Dermatological Research, examined the published evidence on vape and skin effects across multiple studies. Key findings: e-cigarettes can present harmful effects on skin including contact dermatitis, impaired wound healing, and increased rates of acne lesions in young adult users. A 2019 study cited in the review found that young adults who vaped reported more acne lesions than non-vapers, though direct causation was not established. The reviewers noted that more controlled studies are still needed but the pattern of evidence consistently points to vaping as a contributor to acne in susceptible individuals.

What to do if your acne is worsening from vaping

Three practical steps. First, hydration: drink more water (vaping is dehydrating, especially with high-PG e-liquids). The skin around the mouth recovers fastest from increased internal hydration. Second, step down nicotine: lower nicotine strength reduces vasoconstriction and cortisol effects on skin. Moving from 20mg/ml to 10mg/ml or 0mg often improves breakouts within 2-4 weeks. Third, basic skin hygiene around the mouth: gentle non-comedogenic cleanser twice a day, no touching the face after handling the device. If acne is severe or scarring is forming, see a GP about NHS dermatology referral or topical prescription treatments.

In our Omagh and Strabane stores, customers regularly ask what they can do about acne they suspect is linked to their vape. Below is the practical framework drawn from current UK dermatology guidance and what actually works in real customer feedback.

If your acne is severe, persistent or scarring, the right next step is your GP rather than over-the-counter treatments alone. NHS dermatology referrals are available for treatment-resistant acne and the GP can also prescribe topical retinoids, antibiotics or hormonal treatments where appropriate. Our Omagh and Strabane teams cannot give dermatology advice but can help you switch to lower-strength or 0mg products if you want to test whether vape strength is contributing.
