The condition

Laugh Lines

What are nasolabial folds?

Nasolabial folds are the lines that go from the sides of your nose down to the corners of your mouth. They’re also known as smile lines or laugh lines, because they develop naturally from the way we use our facial expressions. With age, these lines may deepen as collagen and skin elasticity decrease.

Although they’re a normal part of aging, some want to soften them for a more youthful appearance. Treatments can help smooth them out. If that interests you and want to learn more about the option available, our expert team would be able to help you muscle out something that is best for your needs!

  • Crow’s feet: Wrinkles at the corners of your eyes, usually from smiling or squinting.
  • Forehead lines: Horizontal lines across your forehead from raising eyebrows.
  • Frown lines: Vertical lines between your eyebrows that can be caused by frowning.
  • Marionette lines: Lines from the corners of your mouth down to your chin, giving your face a puppet-like appearance.
  • Nasolabial folds: Lines extending from the sides of your nose to the corners of your mouth.
  • Neck wrinkles: Wrinkles that appear on your neck as your skin begins to sag.
  • Smoker’s lines: Fine lines around your lips, typically from smoking or puckering your lips.

When to see a doctor?
Smile Lines Diagnosed
How does it affect you?

Nasolabial folds aren’t a defect and don’t need to be medically addressed, but some opt to minimize their appearance for smoother skin. If these lines begin to get under your skin, there are options that can soften them.

If you want to treat nasolabial folds, it’s ideal to discuss it with a qualified plastic surgeon or aesthetic specialist. Everyone’s skin is unique, so what’s effective for one person may not be effective for another. However, by asking questions and setting expectations, you can find the best nasolabial fold treatment for your needs.

Potential treatment options
The causes
What are the main causes of smile lines?
  • Ageing: As we get older, skin decreases in collagen and elastin production, resulting in sagging skin and deeper facial lines.
  • Smoking: It breaks down the collagen that keeps skin firm, speeding up the formation of facial wrinkles.
  • Sun damage: When we get too much sun, collagen weakens and skin starts to sag.
  • Weight changes: Weight loss can lead to loose skin; weight gain can add fullness, both making the folds stand out more.
The risk factors
Who is more likely to have nasolabial folds?
  • Older adults: Over time, the skin loses its elasticity which makes any lines even more prominent.
  • People with family history: If your parents have permanent smile lines, you might develop it too.
  • People with dry and neglected skin: Not moisturizing or taking care of your skin increases the risk of smile lines.
The complications
Hidden Dangers
What problems can nasolabial folds cause?
  • Deeper wrinkles over time

    As skin sags, the folds may become more noticeable.

  • Uneven skin texture

    The skin around the area may not look smooth.

  • Lower confidence

    Many people are self-conscious about deep nasolabial folds.

  • Makeup issues

    Foundation and powder can fall into the creases, making it more emphasized.

The prevention
Sun Exposure Damages Your Facial Skin
How does sun exposure affect nasolabial folds?

Excessive sun can destroy collagen in the skin, causing it to lose firmness and become more susceptible to wrinkling. You need to use sunscreen and sunglasses to preserve a smoother skin and slow down the aging process.

Ways to protect your skin.

Daily use of sunscreen—at least SPF 30, even on cloudy days. A hat, staying out of the sun. and skincare products with antioxidants can help prevent sun damage, too.

Follow A Good Skin Care Routine
Does skincare prevent nasolabial folds?

Maintaining moisture and health of the skin will delay the onset of deep lines. Using products that contain ingredients like hyaluronic acid, retinol, or vitamin C helps keep skin smooth and firm.

The best skin care product.
Seek hydrating creams, gentle exfoliants and collagen-boosting serums. Regular facials or treatments can also help keep skin fresh and youthful.

Smoking Damages Collagen
Does smoking worsen smile lines?

Smoking breaks down collagen, causing skin to lose its elasticity more quickly. It closes off your blood circulation even more, contributing to early wrinkles and sagging.

Your skin health improves after you quit smoking.

Kicking the habit means your skin receives improved oxygen and nutrients, resulting in healthier skin. Over time skin tones become fairer and wrinkles look shallower.

Healthier Lifestyle Equals Healthier Skin
What role does water play in skin firmness?

Tons of water keeps skin hydrated and plump. Dry skin can cause wrinkles and fine lines to become more pronounced.

Foods for healthy skin.

Consuming fruits, vegetables and foods that are high in healthy fats such as avocados and fish can help maintain skin that is strong and elastic. The antioxidants in berries and nuts defend against skin aging, too.

Avoiding Weight Fluctuations
How does changing weight affect the skin?

Quick weight loss or gain can also stretch or loosen the skin and deepen the appearance of nasolabial folds.

Optimal weight management for healthy skin.

Eating a well-balanced diet and being active helps to keep the skin firm. Moreover, muscle toning through strength training along with your facial exercise helps to reduce sagging as well.
