Why Microneedling is Worth it?

Microneedling is a popular treatment in the world of aesthetics and skincare. From reducing acne scars to rejuvenating ageing skin—and even stimulating hair growth in men—this treatment has generated both excitement and caution in equal measure. How effective is this treatment? Is it safe for everyone to use?

What is microneedling?

Microneedling is also called collagen induction therapy. It uses a device with fine, sterile, needles that creates hundreds of micro-punctures on the surface of the skin. These tiny wounds stimulate the body’s natural healing response, boosting collagen and elastin production—proteins essential for firm, smooth skin.

Professional devices penetrate deeper than home tools. Needle lengths can range from 0.5mm to 2.5mm, depending upon the treatment goal. Microneedling is not only used on the face but can be done on the chest, neck, hands, stomach, and scalp.

Does it Work?

According to numerous dermatology studies, yes—when done properly.

• The 2018 Review Journal of Plastic Dermatology After multiple sessions, microneedling improved the skin texture, acne scars and wrinkles.
• Ideal candidates are those with sun-damaged or atrophic skin and acne scars.
• Effects are usually cumulative, becoming more noticeable after 3–6 sessions, spaced about 4 weeks apart.

Microneedling works best when combined with serums like hyaluronic, vitamin C or platelet rich plasma (PRP), as they penetrate deeper through the microchannels.

Men’s Hair Loss Microneedling

Microneedling can be used to treat male pattern hair loss (androgenetic Alopecia).

Microneedling has been shown to:

• Increase blood flow to stimulate hair follicle growth by increasing growth factors and growth factors
• Improved absorption of topical treatment like minoxidil
• Reactivate dormant follicles of hair by initiating localised healing

A clinical trial published in 2013 International Journal of Trichology Comparing men who use minoxidil only with those who also microneedle weekly, the latter group had four times more new hair growth after 12 weeks. After 12 weeks, the latter group showed four times as much new hair growth.

Results can vary depending on factors such as age, hair loss severity, and genetics. Due to the depth required and possible infection risk, most dermatologists prefer professional microneedling for scalp treatments over at-home rollers.

Microneedling has many benefits

• Reduces fine wrinkles
• Acne scars, stretchmarks and hyperpigmentation are reduced.
• Enhances skin tone, texture, and firmness
• Shrinks pores
• Enhances the absorption rate of skincare actives
• Some cases stimulate hair regrowth
• It is suitable for all skin tones unlike some other laser treatments

Side effects and risks

Although generally safe, microneedling is not without risk—particularly when performed without proper technique or sanitation. Side effects may include:

• Redness, swelling, and mild discomfort for 24–72 hours
• Bruising or pinpoint bleeding in deeper treatments
• Infections that can occur if non-sterile devices are used
• Hyperpigmentation after inflammatory skin conditions, especially darker skin tones
• Acne or Rosacea that has gotten worse

If not properly cleaned, devices used at home are more susceptible to contamination and improper use.

Who Should avoid microneedling?

The following conditions may prevent this treatment from being appropriate:

• Active acne, eczema, or psoriasis
• The history of keloid scarring
• Open wounds or skin infections
• Bleeding disorders and blood thinners
• Seek medical advice before attempting to breastfeed or become pregnant.

What to expect

Most professional sessions take 30–60 minutes, often with a topical anaesthetic to minimise discomfort. Similar to sunburn, mild redness or sensitivity can occur after the procedure. Results may not be visible for several weeks. However, improvements can continue up to six months because of ongoing collagen production.

Post-treatment care includes:

• Avoiding sun exposure
• Using gentle, hydrating products
• Avoiding makeup and active skincare ingredients (retinol, acids) for 48–72 hours

Final Thoughts

Microneedling is more than just a beauty trend—it’s a scientifically supported treatment with real benefits for skin rejuvenation and, in some cases, hair regrowth. It’s important to note that, as with all treatments, this is not a “one-size-fits-all” solution. Consult a licensed dermatologist to ensure the best outcome and safety.

Microneedling may be the solution you’ve been searching for to reduce fine lines or thin hair.
