Does Microneedling Help Acne Scars?

Acne scars are a stumbling block on the road to skin recovery for countless people. Whether it is the pigmentation left by acne in adolescence or the sunken scars caused by inflammatory acne in adulthood, they will leave marks on the face that are difficult to ignore.

Among the many scar removal methods, a new acne removal solution has emerged in recent years, that is, microneedling.

Many people will ask: "Does microneedling help acne scars or even eliminate acne scars?"

This article will answer this question in detail for you.

What is Microneedling?

Microneedling, also known as derma roller or derma pen therapy, is a treatment method that uses a device containing tiny needles to create hundreds or thousands of tiny puncture points on the skin.

This minimally invasive treatment will activate the skin's self-repair mechanism, prompting the skin to produce new collagen and elastic fibers. The method can achieve the purpose of repairing acne scars, fine lines, large pores and other skin problems.

Microneedling can be performed in professional medical institutions or purchased and operated at home.

Working principle of Microneedling

It seems a bit counterintuitive that creating tiny wounds can make the skin better. This is because microneedling simulates the natural physiological mechanism of skin.

• Inflammation phase (0~48 hours): After derma pen needles puncture, the skin releases growth factors and starts repair;
• Proliferation phase (2~5 days): Fibroblasts begin to synthesize collagen in large quantities to fill the depressions in the dermis;
• Remodeling phase (more than 5 days): The new collagen structure is arranged in an orderly manner, making the skin smooth and elastic, and the sunken acne scars are gradually filled.

At the same time, the microchannels created by microneedles can also significantly enhance the penetration efficiency of skin care products, helping the skin to better absorb restorative essences such as hyaluronic acid, Centella asiatica, vitamin C, etc., thereby improving the overall treatment effect.

Effect of Microneedling on different types of acne scars

Different types of acne scars naturally have different effects:

For pigmented acne scars, microneedling can promote melanin metabolism, making the skin more transparent and uniform;

For depression-type acne scars, microneedle-stimulated collagen production can gradually fill the depression and achieve skin flatness;

But for hyperplastic scars (such as keloids), laser or drug treatment is required, and microneedles alone may stimulate hyperplasia.

Scientific research supports Microneedling for acne scars

A large number of clinical studies have shown that Microneedling has significant effects on mild to moderate acne scars:

A study published in Dermatologic Surgery showed that after 6 consecutive Microneedling sessions, more than 80% of patients had significantly improved acne scars and improved skin smoothness;

Another German study compared Microneedling with lasers and found that microneedling has similar effects on sunken acne scars, but with fewer side effects and a shorter recovery period;

These data confirm that Microneedling is not a gimmick, but an effective treatment supported by medical evidence.

Recommended tools for at home Microneedling: Derma Pen

If you want to try Microneedling at home, it is recommended to use an electric Derma Pen. Its advantages include:

Vertical puncture, compared with rolling needle, has smaller wound and less pain;

Different needle lengths are selected according to different types of acne scars, and different treatments are applied according to specific conditions, such as 0.5mm for acne scars and 1.0~1.5mm for sunken scars;

During the treatment process, puncture is stable and less harmful;

The more popular ones include: Diaminy Derma Pen, which has been welcomed by many customers for its high performance and high cost performance.

Real case sharing

Case 1: 22-year-old girl, obvious red acne scars

Using 0.5mm microneedle pen + vitamin C essence, once a week for 4 weeks, the marks are significantly lightened and the skin tone is brightened.

Case 2: 30-year-old male, sunken scar on chin

Using 1.5mm Derma Pen with B5 essence, after 6 treatments once a month, the depth of the depression is significantly relieved and the skin elasticity is improved.

Risks of Microneedling

Although Microneedling is a low-risk treatment, improper operation may also cause the following problems:

• Postoperative redness, swelling, and slight bleeding: normal reactions that will be relieved within a few hours to 24 hours;
• Infection risk: Failure to sterilize the tools or improper postoperative skin care may cause bacterial infection;
• Pigmentation: Failure to protect the skin from the sun or use of irritating skin care products may cause darkening.

Usage suggestions:

• Keep the tools clean and replace the disposable needles each time;
• Avoid makeup and hot baths 48 hours after use;
• Use soothing and repairing products with hyaluronic acid, vitamin E, etc.;
• Be sure to use sunscreen after each treatment, SPF30 or above.

Who is Microneedling suitable for?

Suitable people:

• People with red marks, black marks, and sunken acne scars;
• People who want to improve skin luster, firmness, and large pores;
• People who are unwilling to accept high-intensity medical beauty (such as lasers and radio frequencies);
• People who are patient and can provide continuous care.

Not suitable for people:

• Active acne is not under control;
• Skin infection, eczema, rosacea and other problems;
• Pregnant women, breastfeeding women;
• People with scar or allergic constitution.

How long to remove acne scars using Derma Pen?

Many friends who are new to microneedling are concerned about a question: How long does it take to see obvious lightening effect after using Derma Pen?

In fact, removing acne scars is not one shot to see the effect, but a process of gradual repair and improvement. The speed of effect is affected by many factors.

1. The time required varies according to the type of acne scar

Pigmented acne scars are relatively easy to handle because they only affect the epidermis or shallow dermis. Generally, after 2-3 consecutive uses, that is, once a week, about 3-4 weeks can see obvious pigmentation reduction and brightening of skin color.

As for sunken acne scars, since deep skin tissue is involved, it takes time for the skin to secrete new collagen to fill the depression. It is generally recommended to perform microneedle treatment every 2-4 weeks, and continue for 3-6 times as a course of treatment. The effect will gradually accumulate and appear.

2. Individual differences will also affect the effective period

The speed of skin repair is closely related to age, skin condition, and metabolic level. For example, young skin has strong regeneration ability, short repair cycle, and faster effect; while skin with thick stratum corneum or long-term dehydration may need longer maintenance to truly see qualitative changes.

3. Use suitable products to accelerate the effect

After using Diaminy Derma Pen, use a strong repair essence (such as hyaluronic acid, Centella asiatica, niacinamide, B5, etc.) to significantly speed up skin recovery and improve the overall effect. The choice of skin care products and the standardization of postoperative care will also directly affect the speed and effect of acne scar removal.

Summary: Microneedling is a safe and effective scar-lightening tool

Back to the original question: Is Microneedling effective for acne scars?

The answer is: absolutely effective, provided it is used properly and maintained.

Diaminy provides high-quality derma pens, which can stimulate skin regeneration and activate collagen synthesis through regular punctures with tiny needle tips, fundamentally improve acne scars, and improve overall skin quality.
