Are you standing in front of the mirror, worried about a dark spot in the same spot, and unsure of what treatment to choose? In cosmetic dermatology, the basic approach is to first accurately identify the type of dark spot before developing a treatment plan. Melasma, in particular, tends to worsen with strong irritants, so in the early stages, it’s safest to follow an approach that calms inflammation using oral tranexamic acid, topical treatments, and sun protection. Skin spot removal at a cosmetic dermatology clinic isn’t about “one machine solving everything”; instead, we aim for gradual, gentle improvement by selecting treatments step by step based on the condition of your skin.

[Doctor’s Point] Although we use the general term “dark spots,” they can actually take various forms—such as senile lentigines, melasma, and post-inflammatory hyperpigmentation—and it’s not uncommon for multiple types of brown spots to coexist. Therefore, rather than deciding on a treatment based solely on the initial diagnosis, it’s important to monitor the patient’s progress and adjust the treatment plan or add additional treatments as needed. Let’s approach treatment from a long-term perspective, aiming not only to remove dark spots but also to achieve skin that is less prone to recurrence.

Even if spots appear the same at first glance, the appropriate treatment varies depending on their cause and depth. It’s important to first understand the characteristics of each type and address them in an order that prevents them from worsening.

Types of Stains and How to Identify Them

• Senile lentigines: Well-defined spots that develop due to aging and UV exposure. They often appear scattered across the skin.

• Melasma: A hazy, brownish-black discoloration that spreads symmetrically across the cheeks. It is susceptible to friction, hormonal changes, ultraviolet rays, and blue light.

• Freckles: These are strongly influenced by genetics and appear as fine spots, primarily on the nose and cheeks.

• Post-inflammatory hyperpigmentation: Discoloration that remains after acne or scrapes. It may fade over time.

• Dermal melanocytosis: Bluish to grayish spots originating in the deep layers of the skin. Like Ota’s nevus, it is a type of birthmark and requires multiple treatment sessions.

Diagnoses are made comprehensively, not only through visual inspection but also by using magnification and adjusting lighting conditions as needed. In cosmetic dermatology, we also inquire about your lifestyle and skincare habits, placing a strong emphasis on reducing factors that could lead to recurrence or worsening of symptoms.

Start treating melasma with a gentle approach

Since melasma tends to worsen with irritation, it is important to focus on reducing inflammation and stabilizing the basal layer rather than attempting to remove melanocytes all at once with intense light or heat from the outset. Specifically, the foundation of treatment consists of combining oral tranexamic acid with low-irritation topical treatments, gentle cleansing and moisturizing without rubbing, and thorough UV protection. In addition, we consider an approach that gradually reduces melanocytes using toning (long-wavelength laser toning), which removes them incrementally with long wavelengths. Alternatively, treatments such as Potenza—an example of needle RF—can be used to resolve micro-inflammation and stabilize the skin barrier and basal layer. This may help minimize the reaction and downtime associated with subsequent light-based treatments. Since effectiveness, duration, and patient experience vary from person to person, we will make fine adjustments as we monitor your progress.

Clarifying the Roles of Major Treatment Options

• Pico lasers, such as PicoSure, are particularly well-suited for treating localized senile lentigines and freckles, targeting pigmentation with precise energy delivery. Post-treatment protection and UV protection are essential.

• IPL: For those who want to even out redness, uneven skin tone, and small spots across the entire face. This treatment uses a broad spectrum of wavelengths and is a good option when aiming to improve overall brightness and skin texture.

• Needle RF, Potenza, and similar treatments are used for skin with enlarged pores and uneven texture by promoting collagen production. For melasma-affected areas, these treatments are combined in stages with a focus on stabilizing the basal layer.

• Oral and topical treatments—such as tranexamic acid and skin-lightening topical products—serve as a foundation. They are effective on their own and are also intended to enhance the effectiveness of other treatments.

The criteria for choosing a treatment aren’t about which one is superior, but rather whether it suits your specific concerns and lifestyle. There is a wide range of factors—such as pain, downtime, the number of visits, and cost—and these can vary depending on your skin type and the season.

Criteria for Choosing a Cosmetic Dermatology Clinic: How to Find the Right One for You

• Diagnosis: What type of age spot is it? Is it a mixture of types?

• Daily Life and Schedule: Important events and sunburn risks.

• Downtime Tolerance: The number of days during which tape coverage or redness can be tolerated.

• Frequency of Visits and Budget: Should we plan for multiple visits, or proceed in stages?

• Skincare Routine: Is It Necessary to Address Friction and Dryness?

• Determining Whether Oral Medication Is Appropriate: Reviewing Medical History and Concomitant Medications.

Risks and Precautions

All treatments may cause redness, stinging, temporary changes in skin pigmentation, or dryness. Since post-inflammatory hyperpigmentation or worsening of melasma may occur in the treated areas, we carefully adjust the energy output and treatment intervals. Protecting your skin from UV rays and keeping it moisturized also help prevent recurrence. We will perform test treatments and make gradual adjustments as needed, and we will work with you to develop a treatment plan based on the understanding that the onset and duration of results vary from person to person.

Frequently Asked Questions

How many times does it take for it to fade?

It depends on the type and extent of the condition. While age spots may show improvement after just a few treatments, melasma tends to stabilize more easily when a gradual treatment period is established, incorporating both oral and topical therapies.

Which is better, PicoSure or IPL?

The purposes are different. If the goal is to target the darkness of scattered spots, we often choose pico-second lasers; for improving overall skin tone and texture, we often choose IPL. If both types of concerns are present, we consider the order and combination of treatments.

Can you see "Before & After" results for melasma?

We may show you this as a reference during your examination, but individual responses and progress may vary. Please keep in mind that melasma typically improves gradually while inflammation is being controlled.

How long should I continue taking oral tranexamic acid?

We will adjust the treatment over a period of several weeks to several months, while monitoring your skin’s reaction and overall health. Since suitability may vary depending on your medical history and other medications you are taking, we will proceed safely after consulting with your doctor.

Summary

When treating dark spots at a cosmetic dermatology clinic, it’s important to identify the specific type of spot and develop a step-by-step treatment plan. For melasma, an effective approach involves starting with oral or topical treatments such as tranexamic acid, along with anti-inflammatory care. This is followed by toning—which gradually reduces melanocytes using long-wavelength light—and, if necessary, needle RF to stabilize the basal layer. For senile lentigines and freckles, another effective approach is to combine PicoSure and IPL treatments in stages. Since results and downtime vary from person to person, let’s work together at our cosmetic dermatology clinic to develop a treatment plan that fits your lifestyle and skin type. If you’d like to find out if this is right for you, please feel free to schedule a consultation.

The most important thing in treating dark spots is not to judge them solely by their appearance as “dark spots.” In reality, many cases involve a mixture of different types of brown spots—such as senile lentigines, melasma, and post-inflammatory hyperpigmentation—and the treatment methods and order of treatment vary for each. Therefore, laser or light therapy alone will not solve all these issues. It is important to first make an accurate diagnosis, select a treatment suited to your current skin condition, and, if necessary, add additional treatments or revise the treatment plan. Furthermore, through ongoing management—including UV protection, skincare, and controlling inflammation associated with melasma—as well as measures to prevent recurrence, it becomes easier to maintain a healthier skin condition for a longer period. The fundamental approach to dark spot treatment in cosmetic dermatology is not merely to temporarily lighten the spots, but to assess the skin as a whole from a long-term perspective.

Acne varies depending on age, skin type, and lifestyle. A cosmetic dermatology clinic is a place where professionals identify the root causes of your acne and help you find a balanced combination of topical treatments, oral medications, procedures, skincare routines, and lifestyle adjustments—all tailored to your needs. Since pain levels, downtime, and the timing of results vary from person to person, making minor adjustments along the way and sharing your progress are the keys to successful treatment. If you’d like to find the approach that’s right for you, feel free to consult with a cosmetic dermatologist.

The causes and aggravating factors of acne often differ between adolescents and adults, so it’s important to choose a treatment tailored to each individual. Starting the right treatment early on not only helps reduce inflammation but also helps prevent hyperpigmentation and acne scars. If you’re struggling with acne that doesn’t seem to clear up or with recurring breakouts, don’t suffer in silence—please consult a cosmetic dermatologist.
