Understanding Wrinkles: Types, Causes, Prevention, and Treatments

Wrinkles are a natural part of the aging process, appearing as creases, folds, or ridges in the skin. They can develop on various parts of the body, particularly on areas exposed to the sun, such as the face, neck, hands, and forearms. 

Here, we’ll explore the different types of wrinkles, their causes, prevention tips, and treatment options.

Understanding the Different Types of Wrinkles

There are two major categories of wrinkles: dynamic and static. Over time, dynamic wrinkles may evolve into static ones.

Dynamic wrinkles

These form from repeated facial movements and expressions, such as smiling, frowning, squinting, or furrowing the brow. Over time, our facial muscles create creases in the skin, leading to dynamic wrinkles such as: 

  • Frown lines (lines between the eyebrows)
  • Forehead lines (horizontal lines caused by raising eyebrows)
  • Bunny lines (wrinkles on the sides of the nose)
  • Smile lines (lines that appear when smiling, not to be confused with nasolabial folds)
  • Crow’s feet (lines that appear at the outer corners of the eyes when squinting or laughing)
  • Lip lines (formed when pursing lips, such as during smoking or drinking from a straw)
  • Mental crease (formed with the puckering of the chin)

Static wrinkles

These types of wrinkles are present regardless of facial movements. They are the result of sun damage, aging, and a decrease in collagen and elastin—the proteins responsible for our skin’s elasticity–as well as the pull of gravity. Sun exposure plays a significant role in the appearance of static wrinkles, as UV rays break down collagen and elastin fibers. 

It’s important to note that with repetitive facial expressions and aging, dynamic wrinkles can eventually become static as the skin loses its elasticity.

Some examples of static wrinkles are:

  • Nasolabial folds (lines that run from the nose to the corners of the mouth)
  • Marionette lines (lines that run from the corners of the mouth downward)
  • Jowls (sagging skin around the chin or jawline)
  • Crow’s feet (although these can be dynamic initially, they often become static over time)
  • Forehead wrinkles (these too can start as dynamic and become static)
  • Wrinkles on the cheeks caused by loss of volume and elasticity
  • Vertical lip lines (wrinkles above the upper lip)
  • Neck wrinkles

Factors Influencing Wrinkle Formation

Wrinkles result from a combination of genetics, lifestyle habits, and the natural aging process. 

Collagen and elastin levels

These vital proteins give our skin its youthful bounce and stretch. As we age, their production decreases, resulting in the appearance of wrinkles.

Facial expressions

Repeated facial movements lead to expression lines. Smile lines, laugh lines, and nasolabial folds (the lines that run from the nose to the mouth) are often the result of years of smiling and laughing.


Our genes determine our skin type, its elasticity, and how it retains moisture, all of which are factors that influence wrinkle formation. Additionally, certain genetic predispositions can cause some individuals to produce less collagen and elastin over time, making them more prone to the early onset of wrinkles compared to others.

Skin tone

Individuals with darker skin tones have higher levels of melanin, which offers some protection against the damaging effects of UV rays. This often results in a delay in the onset of visible wrinkles compared to those with lighter skin. However, while lighter skin might show wrinkles earlier, darker skin tones are more susceptible to hyperpigmentation and uneven skin tone as signs of aging.

Sun exposure

Sun damage, or photoaging, exacerbates the aging process, leading to sun spots, reduced skin elasticity, and, of course, wrinkles. Regular use of sunscreen with a high SPF can help prevent this.

Wrinkle Treatments

At Circles of Wellness, we offer multiple non-invasive, effective and FDA-approved cosmetic treatments that help prevent and reduce wrinkles of all kinds.

Botox and other neurotoxins

What it is: Botox, Jeuveau and other neurotoxins are injectable treatments containing botulinum toxin, a neurotoxic protein. 

How it works: When injected in small amounts into specific facial muscles, it blocks the neurotransmitter acetylcholine from being released, causing a temporary muscle paralysis. This reduction in muscle activity smooths out the overlying skin. As the muscles relax and can’t contract, the skin remains smooth and unwrinkled.

What it treats: Dynamic wrinkles of all kinds, including forehead lines, glabellar lines (“elevens”) and chin creases.

Dermal Fillers

What it is: Dermal fillers such as Revanesse are injectables typically made of hyaluronic acid, a substance that holds many times its weight in water. 

How it works: HA fillers act like a sponge when injected beneath the skin, absorbing water and expanding to fill in folds and deep wrinkles. They literally “fill” the space, causing sunken or saggy areas to plump up.

What it treats: Dermal fillers are ideal for correcting wrinkles caused by volume loss, such as nasolabial folds, marionette lines, and jowls.  

Chemical Peels 

What it is: A chemical peel typically consists of a mixture of exfoliating acids such as salicylic acid, glycolic acid, and lactic acid, brightening agents, and skin-nourishing ingredients. Some are superficial and involve little actual peeling, while deeper peels can require a week or more of recovery.

How it works: When the chemical solution is applied to the skin, it causes the outer layers to exfoliate and eventually peel off. This process stimulates the skin to regenerate and grow back smoother and less wrinkled. By removing damaged, outer layers of skin, a chemical peel can reveal a brighter, more even complexion underneath.

What it treats: Surface wrinkles, uneven texture, and sun damage.


What it is: Microneedling, also known as collagen induction therapy involves the use of a device equipped with fine needles that create hundreds of tiny, controlled micro-injuries or punctures on the skin’s surface. Some forms of the procedure also incorporate skin-healing RF energy or IPL light therapy.

How it works

The micro-injuries is to trigger the body’s natural wound healing process. As the skin repairs itself, it increases the production of collagen and elastin. Additionally, the tiny channels created by the needles can enhance the absorption of topical serums and treatments, allowing for better penetration and effectiveness of skincare products.

What it treats: Microneedling is particularly effective for fine lines, crow’s feet, and forehead wrinkles. The procedure can minimize the appearance of deeper wrinkles over time with consistent treatments. 

Skin Care for Wrinkle Prevention

The importance of a solid at-home skin care routine cannot be overstated when it comes to preventing and treating wrinkles. We recommend:

  • Daily SPF: Wearing sunscreen every day reduces your exposure to wrinkle-causing UV rays.
  • Hydration: Keeping the skin moisturized ensures its health and can diminish the appearance of fine lines.
  • Regular Exfoliation: Manual or chemical exfoliation encourages the production of new skin cells, promoting a more youthful appearance.
  • Retinoids: Retinoids are derived from vitamin A and promote skin cell turnover, thus helping prevent or reduce the appearance of wrinkles.
  • Vitamin C and other antioxidants: These help to fend off free radicals which accelerate the aging process.


While wrinkles are a natural part of the aging process, there’s a vast array of treatment options available in the world of dermatology. Whether you’re considering botulinum toxin injections, dermal fillers, or simply adjusting your skincare routine, understanding the different wrinkle types and their causes can empower you to make the best decisions for your skin’s needs.

Remember, beyond medical spa treatments, protection against UV rays using sunscreen, ensuring hydration, and employing a rich skincare routine filled with antioxidants, SPF, and collagen-boosting products can make all the difference in the journey of skin aging.
