FAQ Frequently Asked Questions

There is no significant difference between skincare practices in South Korea and Japan in terms of the basic concept of receiving regular skincare treatments at a cosmetic clinic. The practices that have become widespread in South Korea are also being adopted in Japan. At YAYOI CLINIC, we combine cosmetic medical treatments—typically once a month—with at-home care to provide ongoing care tailored to your skin’s condition.

For post-treatment skincare, please follow the instructions provided by your doctor or nurse based on the specific procedure you received. At YAYOI CLINIC, we may recommend the use of medical-grade skincare products or prescription medications depending on the treatment. Since the precautions to take on the day of your treatment vary by procedure, be sure to confirm which products to use and how to care for your skin before heading home.

The choice of treatment for dark spots depends on the type of spot, your skin condition, and your desired results. At YAYOI CLINIC, we use VISIA skin analysis to identify existing dark spots and hidden pigmentation, and we’ll ask whether you’d like to remove prominent spots or even out the overall skin tone. Based on this, we’ll recommend the most suitable treatment, such as laser therapy or IPL (intense pulsed light) therapy.

There are three main types of medical lasers used for removing skin spots: the Q-switched ruby laser, the Q-switched YAG laser, and the picosecond laser. The wavelength, treatment duration, and types of skin spots they are effective against vary depending on the type of laser. At YAYOI CLINIC, we offer the Q-switched ruby laser and the Q-switched YAG laser using the TriBeam Premium system.

The main cause of age spots is ultraviolet (UV) radiation. Aging, hormonal changes, stress, lack of sleep, skin inflammation, and excessive irritation can also contribute to hyperpigmentation. Since the causes and types of age spots vary from person to person, it’s important not to make assumptions based solely on appearance but to have them examined by a doctor.

The main differences between age spots and freckles lie in their causes, size, and appearance. Common age spots (senile lentigines) are primarily caused by exposure to ultraviolet rays and appear as relatively well-defined, circular spots on the face and the backs of the hands. Freckles are strongly influenced by genetic factors and are characterized by small spots, about 2 to 3 mm in size, that are concentrated on the nose and cheeks.

The causes of warts vary depending on the type and include ultraviolet (UV) rays, friction, aging, and viruses. Soft fibrous growths (acrochordons) that appear on the face and neck are caused by UV rays, friction, and aging, while seborrheic keratoses are primarily related to aging. Viral warts, on the other hand, are mainly caused by HPV (human papillomavirus).

Warts may sometimes go away on their own, but this depends on the cause and individual differences. Warts caused by UV exposure, friction, or aging may increase in number or grow larger if left untreated. If a wart does not go away or if you are concerned about any changes, please visit a medical facility to have the type and condition assessed.

Moles are formed by clusters of melanocytes—cells that produce melanin. Some are present at birth, while others develop later in life; factors such as ultraviolet (UV) rays, skin irritation, and hormonal influences are believed to play a role. Since the way moles form varies from person to person, it is not possible to determine the cause based on appearance alone.

Moles include simple naevi, which are usually flat and measure about 1 to 2 mm, and melanocytic nevi, which can range from flat to raised. Their color also varies from light brown to black. Since it is impossible to determine the type based on appearance alone—and because there are other lesions that may look like moles—it is important to have any concerning changes examined by a doctor.

Acne occurs when pores become clogged with sebum and dead skin cells, leading to inflammation. Factors such as lack of sleep, an unhealthy diet, stress, and skincare products that don’t suit your skin type can also contribute to acne. Since clogged pores can develop into red, swollen pimples, it’s important to treat the condition appropriately.

If you experience severe itching after popping a pimple, do not try to treat it on your own; instead, have a dermatologist or cosmetic dermatologist examine the area. While red pimples can sometimes cause itching, the cause of the itching after popping a pimple cannot be determined based on symptoms alone. It is important to have a doctor determine the cause during an examination and receive appropriate treatment.

Treatment can also help make crater-like acne scars less noticeable. At YAYOI CLINIC, we consider treatments such as Potenza or Dermapen 4 for shallow indentations, and subcision for cases where there is hard tissue beneath the skin. However, the degree of improvement and the course of treatment vary from person to person, and it is not always possible to fully restore the skin to its original condition.

Even when pores appear prominent due to acne scars, we can explore treatment options tailored to your skin’s condition. Sometimes, post-inflammatory scarring may resemble pores, while other times the pores themselves may be noticeably enlarged—and it can be difficult to distinguish between the two based on appearance alone. At YAYOI CLINIC, we’ll assess your condition during a consultation and recommend treatments such as Potenza.

Enlarged pores can be made less noticeable through treatments tailored to their underlying causes and your skin condition. At YAYOI CLINIC, we offer options such as TriBeam Premium, which is designed to tighten the skin, and Potenza, which uses micro-needles and radiofrequency. We’ll assess the condition of your pores during your consultation and recommend the most suitable treatment.

For melanin-related pores, treatments such as laser therapy and chemical peels may be considered depending on the degree of pigmentation. Since the underlying cause differs from that of clogged pores, cleansing alone may not be sufficient in some cases. At YAYOI CLINIC, we assess your skin condition and aim for gradual improvement by combining treatments as needed.

Our skin rejuvenation and brightening treatments aim to achieve a radiant, translucent complexion by addressing issues such as dullness, uneven skin tone, and dryness across the entire face. At YAYOI CLINIC, we offer laser treatments for dark spots, as well as IPL (intense pulsed light) therapy, chemical peels, and IV therapy. We take a holistic approach, considering both your specific concerns and the overall condition of your skin when determining the best treatment plan.

Causes of dull-looking skin include dark spots, freckles, a buildup of dead skin cells, dryness, and poor blood circulation. For example, dryness can disrupt the skin’s texture, and the fine unevenness on the surface can cast shadows, giving the skin a dull appearance. Since there isn’t always just one cause, it’s important to choose a skincare routine that suits your skin’s condition.

Facial redness is caused by the dilation of capillaries near the skin’s surface, allowing the color of the blood to show through, or by skin inflammation. It can manifest in various ways, such as redness on the cheeks or the sides of the nose, or a flushed appearance across the entire face. Since the appropriate treatment varies depending on the cause, it is important to have a doctor examine your skin if the redness persists.

Facial redness caused by dilated capillaries is a condition in which blood vessels in areas such as the cheeks and nose appear red just beneath the skin’s surface. On the other hand, facial redness caused by inflammation is associated with irritants such as acne, dry skin, and dermatitis. Since it is difficult to pinpoint the cause based on the appearance of the redness alone, we will examine the location and pattern of the redness during your consultation.
