What is a stain
A blemish is an accumulation of melanin pigment in the epidermis of the skin. There are different types of blemishes, and in many cases there is a mixture of different types of blemishes. Different treatments are suitable for different types of stains. Therefore, it is difficult to obtain pure white skin with no blemishes using only one method. When it comes to blemishes, prevention is often the best cure. First, we will explain the causes of blemishes, and then explain the types of blemishes and recommended treatments.
Cause of blemishes
Blepharoptosis can be congenital or acquired. Congenital ptosis can be an underdevelopment of the musculature within the eyelids or a problem with the shape of the eye you were born with. Acquired is aponeurotic ptosis, in which the muscle that lifts the eyelid (levator palpebrae superioris muscle) is separated from the eyelid, and eyelid skin that is difficult to see because the eyelid skin that has been stretched due to aging is heavy and covers the eye. There is flaccidity, and a combination of both. If it develops suddenly, it is better to consult a neurologist as soon as possible because a problem with the nerves or brain is suspected.
cause of spots
Freckles/freckles
Fine spots on the cheeks that are often seen in relatively young and fair-skinned women. It is exacerbated in the summer by UV exposure. It is a good indication for IPL light therapy, but it can also be treated with Q-switched YAG laser spot irradiation. There is a constitutional factor that causes repeated relapses even after treatment, so continuous treatment is necessary to maintain a good condition.
solar pigmentation
Relatively large, well-defined blemishes seen in older people. Also called age spots. IPL light therapy makes it thinner, but it cannot be removed, so Q-switched YAG laser is indicated. Darker or thicker skin may require multiple treatments. After treatment, inflammatory pigmentation occurs with a probability of about 60%, but it will be completely cured after several months.
chloasma
Bilaterally symmetric, well-demarcated pale blotches seen in women in their 30s and 40s. It can also appear on the forehead and nose, but not around the eyes. It is resistant to treatment with devices such as Q-switched YAG laser and IPL, and lifestyle guidance and oral medication are the basic treatments. There are pros and cons to laser toning, but there are clinical cases in which melasma gradually improves with multiple mild treatments. Hydroquinone application and Transamin oral administration are recommended.
seborrheic keratosis
It often occurs in swollen spots on the temples and sun-exposed areas of the elderly. It does not respond to Q-switched YAG laser or IPL light therapy. Although it is possible to treat by frozen coagulation with liquid nitrogen at a dermatologist and covered by insurance, it may take more time and more times for large or frequent cases. In most cases, high-frequency scalpels and CO2 laser resections are covered at their own expense.
Acquired dermal melanocytosis (ADM)
ADM is a bilateral symmetrical blemish that occurs in women in their 20s and 30s, and is a gray to bluish blackish pigmented spot due to the presence of melanin pigment deep in the skin. Because the lesion is in the dermis, it does not respond to IPL light therapy. Deep lesions are strongly irradiated with melanin-selective Q-switched YAG laser, and the treatment gradually thins over multiple treatments.

The equipment that Motomachi Marine Ophthalmology uses to remove blemishes is Lutronic's Spectra Q-switched yag laser.Spectra has a short wavelength in nanoseconds and irradiates melanin with a highly absorbing wavelength laser to cause thermal coagulation. The melanin-rich spots form scabs and peel off, leaving new skin underneath to heal. Thick stains and warts may not be removed in one go.
Irradiation takes only a few minutes, but it is painful, so if you are sensitive to pain, we have the option of applying anesthesia tape or applying anesthesia cream. Covering with tape is required for 2 weeks after irradiation. After that, try to avoid UV rays with sunscreen.
In addition, inflammatory pigmentation, which turns reddish-black where the stain has been removed, occurs with a probability of about 60%. Inflammatory pigmentation peaks after one month, then fades with the passage of time and blends with other skin colors in about half a year. Whitening agents such as hydroquinone may be used.
