Lip Lines (Smoker's Lines): Causes and How to Soften Them

Updated · 5 min read · By the Renewa Skin team

Vertical lines above the upper lip — often called smoker's lines or barcode lines — are common as skin matures, and you don't have to be a smoker to get them. The skin around the mouth is thin and constantly moving, which makes it one of the first areas to show fine lines. Here's what causes them and what helps.

What causes lip lines?

The muscle that circles the mouth contracts thousands of times a day as you talk, eat, drink, and smile. Over the years, as collagen declines and skin thins, those repeated movements leave fine vertical lines. Sun exposure, smoking, drinking through straws, and dehydration all contribute.

Prevent them from deepening

Small habits make a real difference around the mouth:

  • Apply sunscreen to the upper lip area, and use a lip balm with SPF
  • Avoid smoking and reduce habitual pursing, like using straws
  • Keep the area moisturized — dry skin makes lines look deeper

Skincare that helps

The skin above the lip can be sensitive, so introduce active ingredients slowly. A retinoid at night (starting a few times a week), a hydrating serum with niacinamide or hyaluronic acid, and a rich moisturizer form a solid base routine.

Using an at-home device on lip lines

Large LED masks often don't reach the upper lip evenly. A handheld device with a small head can be guided precisely over the area. With the Renewa iLift, finish your smile-line and marionette-line routine with a few gentle horizontal passes across the upper lip using light pressure.

As with any at-home routine, results are gradual and depend on consistent daily use.

Professional options

For deep lip lines, a dermatologist can discuss options such as resurfacing lasers, microneedling, or small amounts of filler. An at-home routine can complement these treatments or serve as a gentle first step.

Frequently asked questions

Can you get lip lines without smoking?

Yes. Repeated mouth movements, sun exposure, and natural collagen loss cause lip lines in many non-smokers.

What is the best at-home treatment for lip lines?

A combination of daily SPF, a retinoid, good hydration, and consistent use of a gentle targeted device tends to work best for softening their appearance.
