Microneedling Pen GuideHow to treat acne scars and pitted skin, how often to do it, and post-treatment care at a glance

While microneedling pens operate on a straightforward principle, the depth and type of acne scars vary for each individual. This requires a physician with sufficient clinical experience to determine the appropriate needle depth, the best active ingredients for infusion, and whether other treatments should be combined.

When you consult with a doctor, we recommend directly asking about their experience treating acne scars. Observe whether they can specifically explain your scar type and the corresponding treatment approach, rather than giving vague or general answers.

If a doctor can clearly identify which areas need more intensive treatment and which require a lighter touch, it usually indicates a solid foundation of clinical experience in assessing acne scars.

When evaluating a clinic, it's important to check whether the venue clearly lists treatment items and their costs on a fee schedule. Avoid clinics that only provide quotes during the consultation or use vague language about pricing.

Complete pricing information allows consumers to prepare mentally and financially before treatment, and it also reduces the likelihood of misunderstandings or unexpected add-ons later.

During your consultation, proactively ask the clinic for written or publicly available pricing details. Confirm the number of sessions in a treatment package, the intervals between them, and whether follow-up care or return visits are included, to prevent discovering discrepancies halfway through your treatment.

Beyond the doctor's experience, it's crucial to verify whether the equipment itself is authorized by the original manufacturer, as not all microneedling devices have the same safety certifications. Unidentified parallel imports may lack stable energy output and proper safety mechanisms, potentially affecting the consistency and safety of long-term treatments.

Also, pay close attention to the probes and needle consumables that directly contact the skin. Ensure they are individually packaged and replaced after each treatment, as this directly impacts hygiene and infection risk during treatment. We recommend directly asking the clinic about the source of their consumables and replacement procedures during your consultation, rather than relying solely on verbal assurances.

When using a microneedling pen, the ideal depth varies depending on the severity of the indentation and the type of scar. If a clinic uses a fixed depth for everyone, regardless of their individual condition, the results may be compromised or even cause unnecessary stress to the skin.

It's advisable to ask the doctor if they adjust the treatment depth for each area based on your skin condition and acne scar type, and to explain their general adjustment logic before the procedure.

Additionally, incorporating medical-grade serum infusions can enhance the repair process. This is an extra benefit you can inquire about and compare among different clinics.

Acne scars can be broadly categorized into three types based on their appearance: rolling, boxcar, and ice pick. Each type varies in depth and edge sharpness, requiring different treatment approaches.

Rolling scars have gentle, sloping edges and are typically shallower. They often respond well to microneedling, which stimulates collagen production to gradually smooth the skin's texture.

Boxcar scars have distinct, sharp edges and are of moderate depth. These usually require multiple treatment sessions to see noticeable improvement.

Ice pick scars are deep, narrow, and highly fibrotic. Microneedling alone often provides limited improvement for these scars, so combining it with other treatments is usually recommended for more significant results.

Therefore, microneedling is best suited for shallow to medium-depth, broader depressed scars. For deeper scars, it's advisable to consult with a doctor to discuss the possibility of combination therapies before deciding on a treatment plan.

Microneedling pens and fractional lasers are both common treatments for acne scars, but they work differently. A microneedling pen uses tiny needles to create micro-injuries in the dermis, stimulating self-repair and collagen production. This method has a relatively shorter recovery period and is more effective for shallow to medium-depth, widespread indented scars. It's also a good option for those with sensitive skin or who can't tolerate a long recovery time.

Fractional lasers, on the other hand, use light and heat energy to create microscopic thermal damage points on the skin, also stimulating collagen regeneration. Because the heat energy works differently, it can be more powerful for deeper or more fibrous scars. However, the recovery period is typically longer, and there's a higher chance of post-treatment redness and peeling.

Neither treatment completely replaces the other. The best choice depends on the depth of your scars, your skin's sensitivity, and your acceptable recovery time. It's best to discuss these factors with your doctor before deciding. Many people also opt for a combination of both treatments to achieve more comprehensive improvement.

Collagen regeneration is a gradual process that takes time, so you typically won't see a dramatic difference after just one session. This is a common misconception that leads many people to give up if they don't see immediate results.

Most recommendations suggest scheduling sessions every 4 to 6 weeks. This allows your skin sufficient time to complete repair and collagen remodeling before the next stimulation. Generally, 3 to 6 consecutive sessions are advised, though the actual number varies depending on the depth and area of your acne scars, as well as your skin's healing rate.

Changes may not be very noticeable in the early stages of treatment; it often takes around the third session to start feeling your skin become smoother. Therefore, it's important to patiently follow the treatment schedule. Too short an interval between sessions can actually over burden your skin, won't speed up results, and may even prolong the overall recovery time needed.

After a microneedling treatment, your skin will have numerous tiny channels on its surface, and it's normal to experience redness, slight itching, or tightness for about 1 to 3 days as part of the healing process. There's no need to worry excessively, but it's important to follow the post-treatment care instructions provided by your clinic.

During this period, the focus of your skincare should be on intense hydration and repair. Avoid using irritating products like acids or whitening agents, and it's also recommended to pause makeup application and exfoliation to allow your skin barrier to properly recover.

When outdoors, be sure to enhance sun protection, as skin in the recovery phase is more sensitive to UV rays, and sun exposure can increase the risk of hyperpigmentation. Overall, the first week post-treatment is a critical recovery period; diligent care according to medical advice will help maximize the subsequent collagen regeneration effects and minimize unnecessary post-treatment complications.

Microneedling pens are a minimally invasive treatment, but they are not suitable for everyone. A thorough pre-treatment assessment and disclosure of medical history are crucial.

Avoid microneedling if your skin is currently inflamed with acne (especially pustular acne), cellulitis, or other inflammatory skin conditions like eczema or psoriasis, as this could lead to infection or worsen the inflammation.

Individuals with a history of keloids, abnormal blood clotting, or those taking anticoagulant medications must inform their doctor beforehand to assess suitability. It may be necessary to adjust the treatment approach or postpone the procedure.

Pregnant or breastfeeding individuals, or those who have recently undergone other invasive treatments (such as chemical peels or laser therapy), should also discuss appropriate spacing with their doctor before scheduling a microneedling session. Since everyone's skin condition and medical history are unique, a doctor's in-person evaluation is required to determine actual suitability.

The pain experienced during the procedure varies from person to person, primarily depending on individual pain sensitivity, the depth of the treatment, and the current condition of the skin.

Most clinics apply a topical anesthetic cream before the treatment and use vibration or cooling methods to reduce discomfort. The actual sensation is usually described as a mild prickling or itching, not to an unbearable degree.

If you are particularly sensitive to pain, you can inform your doctor beforehand. They can adjust the application time of the anesthetic cream or the treatment depth to make the entire process more comfortable. You can also inquire about other auxiliary methods to reduce discomfort.

We generally recommend scheduling treatments 4 to 6 weeks apart. This interval allows your skin sufficient time to complete its natural repair and collagen restructuring processes before the next stimulation, aligning with the skin's natural healing cycle.

Scheduling treatments too close together can overstress your skin and may not accelerate results; it could even prolong the overall recovery period. The actual interval should be adjusted based on your individual skin recovery speed, the depth of your acne scars, and your doctor's assessment. It is not a fixed schedule, so we recommend confirming your next appointment with your doctor at each follow-up visit.

The cost of microneedling varies depending on the treatment area, depth, accompanying serums, and the clinic's tier. In Taiwan, a single full-face session typically ranges from NT$5,000 to NT$15,000. Treatments specifically targeting acne scars and indentations often start at NT$8,000, while localized spot treatments cost around NT$3,000 to NT$6,000. If additional serums like PRP or exosomes are included, the per-session cost may increase further.

Acne scars usually require multiple sessions to show improvement, and treatment packages will reflect price differences based on the number of sessions. Therefore, it's advisable to estimate the actual cost based on the total price of the entire treatment course, rather than just the single-session price.

We recommend contacting clinics directly to obtain their fee schedules. Confirm what each session includes, whether serums are part of the package, and if there are any additional fees. Evaluate these details based on your budget and needs, avoiding comparisons based solely on single-session prices without considering the overall treatment plan.

After treatment, the skin surface will have tiny needle channels. Applying makeup too early can increase the risk of infection or irritation from powders and cosmetic ingredients. It's generally recommended to wait at least 1 to 2 days for initial epidermal repair before considering makeup, and to choose products with simple textures and ingredients, avoiding cosmetics that contain alcohol or fragrance.

During the recovery period, the skin is particularly sensitive to UV rays, and sun exposure can easily increase the chance of hyperpigmentation. It's advisable to enhance sun protection and minimize unnecessary sun exposure. When going out, you can also use a hat or umbrella for added protection.

Microneedling stimulates collagen production, which not only helps improve acne scars and pitted skin, but also has the potential to address issues like enlarged pores and fine lines caused by collagen loss. The principle is the same: stimulating the dermis to strengthen the skin's support structure.

However, the degree of improvement varies for each individual, depending on their skin condition and the underlying causes of their concerns. If you have multiple skin issues, it's best to discuss them all with your doctor during your consultation. This allows them to plan a suitable treatment and depth setting that can address several needs in a single session.

Microneedling is a minimally invasive treatment, and common post-procedure reactions include temporary redness, mild swelling, or a feeling of tightness. These typically subside within a few days as part of the body's normal healing process.

However, if post-procedure care is not followed correctly—such as neglecting sun protection or prematurely using irritating products—there is indeed a chance of hyperpigmentation or darkening of the skin. This is particularly true for Asian skin types, which are relatively more prone to post-inflammatory hyperpigmentation that can take longer to fade.

In very rare cases, poor hygiene can also lead to infection. Therefore, it is crucial to choose a clinic with thorough sterilization procedures and patient education, and to diligently follow all post-procedure care instructions to minimize risks.

The cost differences among these three treatments primarily stem from variations in equipment costs, treatment depth, and mechanisms of action; therefore, you cannot simply judge which is better based on price alone.

Hydrafacial focuses on cleansing, moisturizing, and superficial exfoliation. While the cost per session is generally more affordable, its effectiveness for deeper dermal issues like acne scars and pitted skin is limited, making it more suitable as an adjunct to daily skincare.

Microneedling pens can reach the dermal layer, and their cost varies depending on the treatment area and the ingredients introduced.

Picosecond lasers, on the other hand, primarily use optical energy to address pigmentation, acne scars, and skin tightening. Their equipment costs are higher, and thus the cost per session is usually higher. We recommend assessing your specific skin concerns and prioritizing your treatment goals, as only then do cost differences become meaningful for comparison.
