1. Equipment and needle selection
   https://justechbeauty.com/2026/01/08/all-dr-pen-models-the-complete-guide/

Needle Type and Number: Discussion generally agrees that for the face, a 36- or 24-needle cartridge is a common and suitable starting point for most people, balancing coverage and comfort. Microneedling with more needles is often better. Needles with fewer needles (such as 12 needles, 18 needles) are usually thicker and may be used for local scars or texture problems that require more precise and deeper treatment.

“Nano needles”: need to be distinguished from microneedles. It does not puncture the skin, and its main function is to promote product absorption. It can be used as a “mini care” for daily maintenance, but it cannot replace the skin rejuvenation effect of real microneedle.

Equipment comparison: Some experienced users recommend Derminator 2, believing that its motor is more stable and parameter control is more precise, but Dr. Pen M8S is more portable due to its wireless design.

2. Depth and speed parameter setting guide

Depth principle: generally follow the “from shallow to deep” principle. It is recommended to start with a shallower depth and adjust according to skin tolerance.

Face: Usually the depth is set between 0.25mm (cosmetic grade, used for product introduction) to 0.5mm (medical grade, used to improve scars and wrinkles). You can try 0.5mm on the forehead, cheekbones and other parts, but be cautious.

Around the eyes: The skin is the thinnest, so be sure to use the shallowest depth (such as 0.25mm or less) and operate gently.

Body: For stretch marks and cellulite, a deeper depth may be required (up to 1.0mm or more, it is recommended to try after full research), but you still need to start shallow for the first try.

Speed ​​settings: Low speed is more suitable for beginners and easier to control; high speed covers faster but may be more exciting. It is recommended to start at a low speed and then adjust according to needs after getting used to it.

3. Suggestions for pairing with essence

During operation: sterile essence with simple ingredients must be used. Hyaluronic acid (HA) is the safest and most common choice, providing lubrication and helping to hydrate and repair.

For hyperpigmentation: Users have mentioned that using a PDRN (polydeoxyribonucleotide)-containing serum (such as Curenex) can help repair it. However, it is emphasized that avoid using any strong irritating active ingredients (such as high-concentration VC, acids) during operation to avoid severe irritation.

Post-operative recovery: Use a calming mask (such as a medical recovery dressing) immediately after the procedure to help reduce redness. Continue to use moisturizing and repairing products for the next few days.

4. Operating techniques and techniques

Techniques: Common techniques include circular motions, horizontal/vertical linear movements, and stamping. Circular and linear movements are used for large area treatment; the point pressure method is used for local areas that require focused treatment (such as wrinkles, deep scars).

Angle: Keep the device perpendicular to the skin surface to ensure even and effective needle penetration.

Lubrication: During the operation, be sure to keep a sufficient amount of essence on the skin surface as lubrication to avoid skin damage caused by dry rubbing.

Body parts: It is more difficult to operate on uneven parts such as thighs and knees. Some users believe that the microneedle roller may be easier to operate on large areas of the body than a pen-type device.

5. Important matters needing attention

Sterility First: Use new, sterile needles every time, and clean your face and equipment thoroughly before and after procedures.

Frequency cycle: Deep care (depth >0.5mm) should be performed at least 4-6 weeks apart to give the skin sufficient time to repair. Superficial introduction (about 0.25mm) can be done once a week or every two weeks, but skin reaction needs to be paid close attention to.

Preoperative anesthesia: For deeper procedures, it is recommended to use epidermal anesthetic cream to improve comfort.

Postoperative care: Strictly protect yourself from the sun, avoid using irritating skin care products, and strengthen moisturizing.

Learn first: It is strongly recommended that novices systematically watch professional tutorials (such as bloggers such as SkinwithJaymie recommended by users) to fully understand the risks and techniques before operating.

Summary: Home microneedling is an efficient but rigorous skin care method. The key to success is to start with low parameters, focus on surgical rules, focus on sterility and safety, and success or failure depends on postoperative repair. For improving pores, fine lines, superficial scars and body texture, adhering to the correct at-home microneedling regimen has proven to be effective, but for severe skin problems, it is still recommended to consult a professional doctor.

How Mesotherapy Works: Understanding the Process.

Mesotherapy is an innovative treatment that has gained popularity for its ability to address various aesthetic concerns, including skin rejuvenation, fat reduction, and hair restoration. This technique involves the injection of customized solutions containing vitamins, minerals, and other active ingredients directly into the skin, targeting specific areas for optimal results. Whether you’re looking to improve skin tone, reduce stubborn fat deposits, or stimulate hair growth, understanding how mesotherapy works can help you determine if this approach is right for you.

What is Mesotherapy?

Mesotherapy involves injecting small amounts of medication, vitamins, and other substances directly into the skin. The goal is to target specific areas of concern, such as cellulite, wrinkles, or hair loss.

How Does Mesotherapy Work?

Injection Technique: A trained professional at BEAUTY SALON uses a fine needle to inject the solution into the middle layer of the skin, known as the mesoderm. This allows the treatment to work directly at the source of the problem.

What Is Injected?:

The solution can include vitamins, minerals, enzymes, and medications designed to improve skin health, reduce fat, or stimulate hair growth. The exact ingredients depend on the specific goals of the treatment.

Treatment Areas: Mesotherapy can be used on various body parts, including the face, neck, arms, stomach, and thighs. It is also commonly used to treat hair loss in the scalp.

Microneedling has gained immense popularity as a minimally invasive skincare treatment for rejuvenating the skin, reducing acne scars, minimizing wrinkles, and improving overall skin texture. However, while it offers numerous benefits, microneedling is not suitable for everyone. Understanding the contraindications and identifying who should avoid this procedure is crucial for ensuring safe and effective results.

In this blog, we will delve into the specifics of who should avoid microneedling and why. If you’re considering this treatment, it’s essential to consult with an experienced dermatologist like Dr. Priyanka Tambe for personalized advice.

What is microneedling?

Microneedling, also known as collagen induction therapy, involves the use of a device with fine needles to create tiny, controlled punctures in the skin. These micro-injuries stimulate the skin’s natural healing process, boosting collagen and elastin production. The result is smoother, firmer, and younger-looking skin.

While microneedling can work wonders for many, certain individuals may need to steer clear of this procedure due to specific medical conditions, skin issues, or other contraindications.

Who Should Avoid Microneedling?

1. People with Active Skin Infections or Acne

If you have an active skin infection, such as cold sores, or severe acne with open lesions, microneedling is not recommended. The procedure can spread bacteria, potentially worsening the infection or causing complications.

2. Individuals with Skin Disorders

Those with chronic skin conditions like eczema, psoriasis, or rosacea should avoid microneedling. These conditions make the skin more sensitive and prone to inflammation, which could be aggravated by the treatment.

3. Pregnant or Breastfeeding Women

Pregnancy and breastfeeding are sensitive periods when it comes to undergoing cosmetic treatments. While microneedling itself may not directly harm the baby, some serums or topical anesthetics used during the procedure may not be safe. It’s best to postpone microneedling until after pregnancy and breastfeeding.

4. People with Keloid-Prone Skin

If you are prone to developing keloids—thick, raised scars that form after an injury—microneedling is not advisable. The procedure involves controlled skin trauma, which could potentially trigger keloid formation in susceptible individuals.

5. Those Taking Blood Thinners or Certain Medications

People on blood-thinning medications or those who use isotretinoin (commonly prescribed for severe acne) should avoid microneedling. Blood thinners can increase the risk of excessive bleeding during the procedure, while isotretinoin can make the skin more fragile and prone to complications.

6. Individuals with Compromised Immune Systems

If your immune system is weakened due to a medical condition or medications, microneedling may not be safe. A compromised immune system can hinder the healing process, increasing the risk of infection and delayed recovery.

7. Recent Laser or Chemical Peel Treatments

If you have recently undergone laser treatments, chemical peels, or other aggressive skin procedures, you should wait until your skin has fully healed before considering microneedling. Combining treatments too soon can overstress the skin and lead to adverse reactions.

8. People with Skin Cancer or Precancerous Lesions

Individuals diagnosed with skin cancer or those with precancerous lesions should avoid microneedling. The procedure can irritate the affected areas and may interfere with ongoing cancer treatments.

9. Uncontrolled Diabetes or Poor Wound Healing

People with uncontrolled diabetes or conditions that impair wound healing are at a higher risk of complications after microneedling. It’s essential to address underlying health concerns before opting for this treatment.

Alternatives to Microneedling

Several alternative treatments may be safer and equally effective for those who fall under any of the above categories, depending on your skin concerns. Options include:

• Hydrafacials: A gentler, non-invasive way to cleanse and hydrate the skin.
• Chemical Peels: Mild peels can improve skin texture without the risk of micro-injuries.
• Topical Treatments: Serums and creams tailored to specific skin issues.
• Laser Therapy: A controlled alternative for targeting scars, pigmentation, and fine lines.

Why Consult a Specialist?

Microneedling is a powerful skin treatment, but it must be cautiously approached. A trained dermatologist can assess your skin type, medical history, and overall suitability for the procedure. They can also recommend alternative treatments if microneedling isn’t right for you.

There are many derma rollers on the market, and you should distinguish between genuine ones (usually 192 needles) and fake ones (more than 500 needles). Real derma rollers are made up of individual needles, while fake ones look like serrated blades (which are not actually needles)—which can cause serious damage to your skin. For example, if you use counterfeit products, it may cause uneven skin surface, or even scratches and inflammation.

Now that we have those questions out of the way, let’s get back to the main topic and discuss two commonly spread myths about derma rollers:

Myth 1: There is true depth of penetration at 90° using a pen device.

-The needles in a roller come around into a 90° position during rotation as well. There is more chance of not attaining true depth using a pen due to practitioner error if the device is not held perpendicular to the skin.

-Some vendors of electric devices offer needle lengths up to 3 mm. However, almost all devices on the market do not have sufficient power to achieve these depths. After a certain depth, the needles just push away the skin and the skin starts to catch on the needles (fakir effect).

Myth 2; The sloped insertion of the needles on a roller slice or tearing the skin to create trenches (“much more traumatic”) whereas vertical insertion with a pen is less “traumatic”, leading to less downtime.

-Greater erythema may occur with rollers due to the release of histamines from the mechanical pressure the drum exerts on the skin. This lasts hours, not several days, as suggested by some.

-The needles in electronic devices move so rapidly that maceration of the skin may occur, leading to longer downtime. Additionally, it is impossible to know if they are in or out of the skin as the device is moved across it. Thus, there will also be a cutting action (similar to a jig-saw mechanism) involved in using these devices, unless it is held stationary and then lifted to the next spot (stamping technique), in which case the holes will become enlarged because each needle will have penetrated multiple times in the same spot. At the end of the day, the goal is to traumatize the skin, and both modalities do it in such a minimal manner to the point of being non-ablative and non-scarring. Attempts to create distinctive differences between rival devices only serve to confuse clinicians and consumers, while undermining the very science that forms the foundation of all the needling devices. Each device has its valuable place and can be sold on its own merits without distorting the facts.

When performing skin acupuncture, precision and force are crucial. Different types of equipment can affect the final result, so it’s important to choose the right tool. Each device has its own unique design and functionality to meet the needs of different patients. When clinicians use these devices, they should fully understand their scope of application and potential effects in order to provide patients with the best treatment options. The right combination of technology and knowledge will help improve treatment outcomes and ensure patient satisfaction.

Recommendations for Using the Skin Roller

When using a derma roller, you first need to ensure that the equipment is clean and disinfected to avoid bacterial infection. Secondly, choosing the right needle length is crucial, and beginners are usually advised to use shorter needle lengths, such as 0.25mm or 0.5mm. When using, the movements should be gentle and even, and avoid excessive pressure. After each use, it is recommended to apply a repair serum to help the skin recover better.

Additionally, regular replacement of your derma roller is key to maintaining results. It is recommended to replace the needle every 3-6 months to ensure the sharpness and effectiveness of the needle. At the same time, users should regularly consult professionals according to their own skin conditions to obtain personalized care advice.

Sometimes I look at myself in the mirror and wonder if it’s been worth all the money I’m investing, because my face isn’t where I want it to be just yet, and then I make these Before and After collages…the progress is undeniable.

These photos were taken by the exact same window at around the same time of the day. I’m wearing tinted moisturizer in both but nothing else. I have been incorporating hyaluronic acid to my daily routine since I started this MN journey 4 months ago. Also, I don’t know if it does anything but I add a collagen supplement to my coffee every morning.

Feel free to look at my previous post where I detail some more about these sessions I’ve done. Just wanted to post an update as some people requested, and I plan on doing it as I continue to do the next 3 sessions.

-Single-use. No possibility of cross-contamination from blood products of the device itself. (Pens have disposable tips, but the device itself may become contaminated.)

-Faster treatment time for large areas. • Needles don’t get hung up in scar tissue. (Pens often need lubrication on the skin surface to facilitate glide across the skin and tend to hook dense scarring with a glide technique.)

-No need to adjust speed or needle length which reduces the incidence of inadvertent contamination of gloves.

-The pressure applied during treatment can be adjusted to light feathering over the eyelids, whereas the speed and depth of needles with pens is constant. One can slow down and make very cautious calculated moves in high-risk areas with a roller.

Use the roller to better control the depth of treatment, especially in sensitive areas such as around the eyes. – Additionally, recovery time after treatment is relatively short, allowing patients to return to daily activities more quickly.

The design of the roller makes it more flexible when dealing with irregular skin surfaces and can better adapt to different skin types.

Patient safety is improved and medical operations are more standardized due to the avoidance of cross-contamination.

This method is gaining traction in the aesthetic and medical fields, providing professionals with more treatment options.
