Dull skin with fine lines or blemishes can be a huge confidence killer while having a negative impact on your overall health. Studies reveal that poor skin health can have a severe psychological and emotional impact as they lead to depression, anxiety, and social isolation, ultimately resulting in poor quality of life, 

Thankfully, modern cosmetic procedures are super efficient for the glowing and radiant skin you always desired. Gone are the days when you would apply wrinkle-removal creams for weeks only to find minimal improvements. 

One such technique to improve your skin and achieve a youthful appearance is microneedling. It is a popular, minimally invasive cosmetic procedure that enhances your skin internally. The advanced cosmetic technique is effective in addressing various skin conditions. 

So how does microneedling work? Read on to learn more!

What Is Microneedling Therapy?

Microneedling stimulates collagen boost, which ultimately rejuvenates your skin over time. The underlying reason for the loss of skin elasticity with age is decreased collagen production. According to studies, chronologically aged skin shows reduced production of the protein, i.e., collagen, which is attributed to the aging of the cells (fibroblasts). 

Collagen provides structural support and integrity to the dermal layers. It helps regrow new cells that replace the dead ones and tightens and smoothens the skin. An inability to reproduce collagen leaves you with dull, dead skin that appears unattractive.

Therefore, kickstarting collagen production requires a stimulus that promotes the activity of the fibroblasts. An effective stimulus for collagen production is microneedling!

How Does Microneedling Work?

A cosmetic expert or dermatologist uses thin, sterilized needles to create small and precise punctures using a pen-shaped tool. These tiny microscopic wounds stimulate and enhance the deeper layers of skin to trigger a healing activity, resulting in natural collagen production.

There are multiple scientifically proven ways in which microneedling can bring changes in the skin layers. Microneedling works to enhance your skin quality in the following ways:

Collagen Synthesis

The most potent way microneedling changes the skin is collagen synthesis, also known as percutaneous collagen induction (PCI). A study reveals appreciable increases in the levels of collagen types 1, 3, and 7.

A significant increase in tropoelastin levels was also seen, which helps with effective facial rejuvenation. 

A 2021 literature review concludes that percutaneous collagen induction therapy, i.e., microneedling, can manage different skin conditions such as scars and photoaged skin. 

Another study investigated the effect of microneedling on scars and found that the needling techniques show positive results in non-atrophic scar management. This alleviation of scars gets attributed to the percutaneous collagen induction effect.

Research also reveals that microneedling changes collagen gene expression and promotes the production of muscle and extracellular matrix. These changes lead to appreciable facial skin rejuvenation,

Growth Factors Release 

Microneedling also amps up the skin healing process by promoting growth factors release. A comprehensive review reveals that the collagen synthesis and growth factor release-promoting effects of the microneedling procedure get used to correct different skin conditions:

  • Scars
  • Acne 
  • Melasma 
  • Photodamage 
  • Alopecia 

The safe needling procedure is effective in inducing hair growth. Androgenetic alopecia and alopecia areata patients can take advantage of microneedling. An authentic study highlights that microneedling enhances growth factor production in treated areas. This effect combines improved collagen production and neovascularization (growth of new blood vessels) to impart superior results.

Microneedling also upgrades the rate of cell turnover (of fibroblasts). This effect also makes it a cosmetic success. 

Uses and Benefits of Microneedling? 

Microneedling is a promising way to treat various skin conditions, including:

Wrinkles and Fine Lines

Aging skin is an inevitable aspect of our lives. Many women feel the skin aging onset appears very early, marked by fine lines and wrinkles. 

The safest and most effective way to reduce fine lines and wrinkles is microneedling. According to a study, four sessions of microneedling led to significant improvements in skin texture and reductions in fine lines/ wrinkles. 

Biopsy data reveals that microneedling treatment effectively lessens the wrinkles and fine lines in the facial and neck skin.


Acne marks are stubborn and generally do not respond to most anti-scar treatments. The thin microscopic needles can help you get rid of those ugly scars. You can pair microneedling with a derma roller to manage acne scars. The treatment modality is effective and light on the pocket too.

The repair-enhancing effects of microneedling allow the minimally invasive procedure to manage atrophic (post-acne) scars. However, you will need multiple treatment sessions to boost collagen (type 1, 3, and 7) levels. A 2020 systematic review also advocates microneedling for acne scar management.

The betterment in the collagen expression entailed with microneedling can get utilized to lower stretch marks and hyperhidrosis. You can also find improvement in the stretch marks (striae rubrae)

Skin Pigmentation and Tone

Overproduction of the natural pigment melanin can lead to skin darkening. The enhancement in healing/ repair induced by microneedling can help lighten the hyperpigmented skin regions. 

Microneedling is frequently used to manage various skin etiologies, including hypertrophic scars, stretch marks, and vitiligo, thanks to the stimulation of fibroblasts for collagen and elastin production. The treatment modality is helpful for melasma and melanosis patients.

A study concludes that microneedling reduces acne scars and associated hyperpigmentation in dark-colored individuals.

The percutaneous collagen induction technique does a great job of reducing the size of the skin pores. Large skin pores are breeding grounds for pathogens. By shrinking the pore size, it also smooths uneven skin. 

Hair Growth 

As it triggers cells to proliferate, you can expect to see hair growth promotion after microneedling sessions. Animal studies reveal that microneedling induces hair growth by promoting growth factors activation pathways. The results of microneedling are comparable to minoxidil in cases of androgenetic alopecia.

How Can I Find the Best Microneedling Expert?

Microneedling is a safe cosmetic procedure that enhances your body’s repair potential with minimal discomfort to treat skin imperfections. 

Also known as the percutaneous collagen induction procedure, it imparts therapeutic effects by promoting collagen production, increasing cell turnover, and inducing the growth of new blood vessels (neovascularization).
