Scars can be a reminder of what has happened in the past—whether caused by acne, surgery, or accidents—but some might not desire them as a constant reminder. As at-home beauty treatments and clinical procedures gain popularity, the microneedling pen has become a sought-after solution to decreasing the visibility of scars. But do they really deliver?
In this post, we'll explore the science behind microneedling pens, how they can help decrease various types of scarring, the results you can expect, and whether or not it is the right procedure for you.
What is a Microneedling Pen?
It is a portable, needle-based pen that has fine, sterile needles that pierce the outer surface of the skin quite fast. They cause controlled micro-injuries that induce the wound-healing mechanism by the body, releasing collagen and elastin, two vital proteins for the even, firm, and smooth appearance of the skin.
In contrast to standard dermarollers, microneedling pens (also known as dermapens) provide control over both needle depth and velocity, enabling precision treatments for specific spots and for various conditions in different locations.
How Does Microneedling Fade Scars?
1. Stimulates Collagen Production
Scars tend to emerge when skin heals unevenly, either with excessive collagen, and becomes pitted or raised. Microneedling induces micro-wounds that cause controlled amounts of collagen to be produced, evening out uneven textures over a course of time.
2. It Dissolves Scar Tissue
The mechanical effect of the pen assists in breaking down hardened scar tissue. In the long-term, this promotes the regeneration and restructuring of the skin, minimizing the appearance of both old and new scars.
3. Enhances Product Absorption
Microneedling temporarily opens up channels in the skin, enhancing the delivery of scar-reducing serums such as hyaluronic acid, vitamin C, or peptides. This increases the effectiveness of your topical treatments.
Types of Scars Microneedling Pens Can Help With
Microneedling pens have also yielded encouraging results for different scars, but results vary with the type, age, and severity of the scar.
Acne Scars
Microneedling is particularly well-suited for atrophic scars, such as ice pick, boxcar, and rolling scars. These are depressions in the skin due to loss of collagen, and microneedling stimulates regrowth of the collagen to fill and smooth them.
Surgical and Traumatic Scars
Microneedling can also reduce and flatten surgical scars or injuries, particularly those that are hypertrophic (elevated). It's not a miracle cure, but it can make them less prominent with repeated treatments.
Stretch Marks
Stretch marks represent a scarring that occurs due to the stretching of the skin. Microneedling retextures the skin, increases elasticity, and reduces discoloration.
Keloid Scars
Warning: Keloids, which extend outside the original wound and are filled with collagen, generally do not react well to microneedling. In fact, it may even make them worse, so a visit to a dermatologist is required.
What Are the Expected Results?
Microneedling is not a one-day miracle, but rather brings continuous, perceptible improvements with time.
Timeline
• After the treatment, the skin could be slightly swollen, tight, and red (like a sunburn).
• In a week: Both the skin becomes smoother and the texture starts improving.
• After a course of 3-6 treatments (4-6 week intervals): You can expect to see the depth and appearance of scars from acne and minor surgeries reduced.
• Long-term: Collagen production lasts for months, meaning that improvements in the skin could last and even grow greater after finishing treatment.
How Much Scar Reduction?
Research and patient reports indicate that it can decrease scars by 30% to 70% based on the type of scar, depth, and healing response in the individual.
At-home vs. Professional Microneedling Pens
Microneedling pens also have both at-home models and professional-level devices found in spas or dermatologist offices. Which one is right for you?
At-Home Microneedling Pens
• Needle depth: Usually 0.25 mm to 0.5 mm
• Ideally suited for: Improving glow, subtle textural imperfections, and fine pimple scars.
• Advantages: Convenient, economical
• Disadvantages: Shallow depth and outcomes; greater risk if misused.
Professional Microneedling
• Needle depth: To a depth of 2.5 mm for deeper scars.
• Used for: Moderate to severe scars, surgical scars.
• Advantages: safer method, firmer outcome, use of numbing cream.
• Disadvantages: More expensive per session.
Follow best practice by using home pens for minor problems and basic maintenance, but for severe scarring, seek a professional!
Is It Safe?
When performed properly, microneedling is generally safe for the majority of skin types. It is not risk-free, however.
Possible Side Effects:
• Redness, swelling, and scaling (usually resolves in 48-72 hours)
• Risk of infection (when the tools aren't sterilized)
• Skin irritation (particularly when combined with rough products)
• Post-inflammatory hyperpigmentation (in deeper treatments or in darker skin tones)
Sanitize your pen at all times, avoid makeup or harsh products after treatment, and apply sunscreen religiously following microneedling.
How to Use a Microneedling Pen for Scars (Step-by-Step)
Here is a simple step-by-step guide for home use. Make sure to adhere precisely to the guidelines provided for your individual system.
Step 1: Disinfect and Clean
• Wash your face carefully.
• Sanitize your microneedling pen and replace the cartridges when necessary.
Step 2: Use Numbing Cream (optional)
• For deeper needle placement, use a topical anaesthetic cream to alleviate pain.
• Leave it on for 20–30 minutes and wipe off completely.
Step 3: Begin Needling
• Work in small sections, moving the pen in horizontal, vertical, and diagonal directions.
• Do not apply so much force; let the instrument perform the task.
Step 4: Apply Serum
After needling, apply a calming and hydrating serum—hyaluronic acid is ideal.
Step 5: Post-Care
• Avoid sun, makeup, exfoliants, and sweating for 24-48 hours.
• Follow a gentle skincare regime and maintain well-moisturized skin.
Who Should Avoid Microneedling?
Microneedling is not for everybody. You should not use it if:
• Have active acne or infections
• Suffer from eczema, psoriasis, or rosacea flare
• Are susceptible to keloid scarring
• Take blood-thinners or experience poor wound healing
• Are pregnant or breastfeeding (consult a doctor)
What Do Experts Say?
Clinical studies confirm that microneedling is effective for scars.
• One study published in the Journal of Clinical and Aesthetic Dermatology in 2015 demonstrated that microneedling dramatically improved moderate scarring from acne after four treatments.
• Dermatologists generally suggest it as a low-cost, non-surgical substitute for fillers or laser therapy.
• When combined with PRP (platelet-rich plasma), outcomes can be further improved—popularly referred to as the “vampire facial.”
Final Verdict
Does a Microneedling Pen Really Work for Scars?
Indeed—a microneedling pen can dramatically diminish the visibility of scars, provided that it is done regularly and properly. It is not a fix that occurs overnight or a miracle solution, but numerous individuals experience smoother, brighter, less textured skin after a few sessions.
Whether you're treating acne scars, minor surgical scars, or developing stretch marks, microneedling is a tested, non-surgical method that stimulates your skin to repair itself and regenerate.
If you're a newcomer to microneedling or you've had deep scars, begin with a professional consultation. But if you're in need of a low-cost home solution to revitalize your skin texture, a premium-quality microneedling pen could be that secret weapon your beauty regime needs.
