Maximizing Cheek Filler Benefits: Preventing Under-Eye Wrinkles and Enhancing Facial Contours

What Are Cheek Fillers and How Do They Work?

Dermal fillers are gel-like substances injected under the skin to add volume and smooth out wrinkles. Most contain hyaluronic acid, which occurs naturally in the body.

When injected, fillers plump the skin by attracting water and providing hydration. The effects are temporary, usually lasting 6 to 12 months before dissolving.

Why People Get Cheek Fillers

As we age, our faces naturally lose volume, especially in the cheek area, leading to a sunken or hollow appearance. Many people choose to get cheek fillers to:

  • Restore volume loss due to aging.
  • Enhance their cheekbones.
  • Lift and rejuvenate the mid-face.
  • Improve nasolabial folds (smile lines).

Can Cheek Fillers Lead to Under-Eye Lines When Smiling?

Under Eye Cheek Filler

Cheek fillers can cause puffiness or swelling in the under-eye area if the filler migrates or is placed too close to the lower eyelid region, emphasizing fine lines when smiling.

When administered correctly by an experienced injector, cheek fillers should not directly cause new wrinkles or lines under the eyes. Proper placement in the upper cheek area, away from the eyelid, helps minimize risk.

Do Cheek Fillers Make Smile Lines Worse?

Cheek fillers alone may not make smile lines worse, but restoring lost cheek volume with fillers seems important to fully address smile lines caused by tissue descent.

Combining cheek fillers with other treatments like nasolabial fold or marionette line fillers provides the best chance of improving smile lines.

Other Factors That Contribute to Under-Eye Lines

Besides fillers, other factors can cause under-eye lines over time, such as:

  • The natural aging process reduces collagen and skin elasticity.
  • Sun and environmental damage
  • Genetics and facial bone structure
  • Repetitive facial expressions and muscle movements

Why Do I Have Lots of Lines Under My Eyes When I Smile?

Common reasons for more lines under your eyes when you smile:

Repetitive facial expressions like smiling or squinting can lead to fine lines over time. The repeated muscle movement contributes to their appearance.

Aging. As you age, the skin around your eyes naturally loses collagen and elastin, making it thinner and less able to snap back after facial movements. This accelerates the appearance of lines that were previously only visible when smiling or making expressions.

Sun exposure. Unprotected sun exposure can damage the delicate skin around the eyes and break down collagen, promoting the formation of permanent lines and wrinkles.

Lifestyle factors. Smoking breaks down skin collagen. Poor nutrition and inadequate hydration, antioxidants, and vitamins affect the skin's ability to withstand repetitive movements.

Are Smile Lines Good or Bad?

Smile lines aren't "bad," but a natural result of living an expressive, happy life.

Cosmetic procedures like fillers can reduce smile lines, but avoiding smiling to prevent them is not recommended and could have negative psychological effects.

At What Age Do Smile Lines Appear?

Genetics can influence it, but most people notice the first smile lines in their late 20s to 30s. The lines deepen with age into middle age and beyond.

Are Smile Lines Reversible?

Smile lines, also known as nasolabial folds or laugh lines, are generally reversible through various treatments.

Common treatments for reversing smile lines include dermal fillers and laser treatments.

Hyaluronic acid fillers can reduce smile lines by adding volume and smoothing the skin. The effects are immediate and can last 6-12 months before additional treatments.

Can Retinol Reduce Smile Lines?

Yes, retinol can reduce smile lines:

  • Retinol is known for its anti-aging properties and ability to stimulate collagen production, improving skin elasticity and reducing fine lines and wrinkles.
  • Studies have found retinol to reduce fine lines and wrinkles, including smile lines. A 2007 study showed retinol breaks down free radicals causing wrinkles.
  • Retinol is one of the most effective ingredients for addressing aging signs on the skin, including fine lines. Consistent use of a retinol cream or serum can help reduce smile lines.

How to Minimize the Risk of Under-Eye Lines with Cheek Fillers

Choosing an Experienced Injector

To minimize under-eye issues with cheek fillers, choose a highly qualified provider. Look for a board-certified dermatologist or plastic surgeon with extensive filler injection experience. Ask to see their before-and-after photos and read patient reviews.

Proper Filler Placement and Technique

Skilled injectors know precise filler placement is crucial to avoid complications. Cheek fillers should go in the upper cheek area, not too close to the lower eyelid or tear trough. The filler type and amount should be customized to your facial anatomy. Advanced techniques, like using a microcannula instead of a needle, can minimize swelling and product migration.

Combining Treatments for Optimal Results

Cheek fillers may not fully address under-eye concerns. In these cases, combining treatments could be recommended for comprehensive rejuvenation. 

Under-eye filler (tear trough filler) can plump up hollows or dark circles. Resurfacing lasers or chemical peels can improve skin texture and minimize lines. 

Botox injections can smooth crow's feet and dynamic wrinkles caused by muscle movements.

Aftercare and Maintenance for Cheek Fillers

Post-Treatment Care

Right after getting cheek fillers, there are things you can do to minimize swelling and promote healing:

  • Apply cold compresses or ice packs as directed.
  • Avoid intense exercise, alcohol, and excessive heat for the first 24-48 hours.
  • Sleep with your head slightly elevated to reduce fluid buildup

Long-Term Maintenance

To ensure your cheek fillers look great for as long as possible, take care of your skin:

Keep Your Skin Hydrated and Healthy

A good skincare routine can make a big difference. Use a gentle cleanser, a suitable moisturizer, and stay hydrated by drinking plenty of water.

Protect Your Skin from the Sun

The sun can be tough on your skin, especially after fillers. Use SPF 30 sunscreen daily, even when it's cloudy. Wear a hat and sunglasses if you'll be outside for a while.

Schedule Regular Touch-Ups

Cheek fillers don't last forever. To maintain your look, you'll likely need touch-ups every 6-12 months. Your injector can help you decide the best timing based on the filler type and your skin's response.

Consider Other Treatments

Cheek fillers may not be enough. Your doctor might suggest other treatments like lasers or chemical peels to help your skin produce more collagen and look smoother.


Cheek fillers restore face volume and reduce smile lines. Choosing the right injector and proper aftercare can prevent issues like under-eye lines. Every face is unique, so consult a qualified professional for the best treatment plan.
