As the weather gets warmer, thick makeup can feel burdensome, and many people become more concerned about seborrheic keratosis that they've been covering up. Even if you apply concealer, it can easily smudge in hot weather, causing stress. We've organized frequently asked questions about why seborrheic keratosis occurs and how to manage it.

Seborrheic keratosis is also known as solar keratosis and primarily appears on the face, hands, or neck in people over 40. Since it appears as dark brown or black spots, it is often difficult to cover even with a thin layer of foundation.

Seborrheic keratosis itself does not harm your health, but many people wish to remove it for cosmetic reasons if it appears on exposed areas like the face or neck. However, there are various types of pigmented lesions, so the first step is to confirm what kind of lesion it is through a medical examination rather than self-diagnosis.

The laser introduced here uses a 532nm wavelength and is utilized for various pigmentation management, including vascular and pigmented lesions. It works by delivering energy to the tissue through a handpiece, and it is designed to target only the desired area, reducing the burden on surrounding skin.

We have been informed that the pain is relatively low due to the application of a supercooling technology. Recovery time and the degree of pain may vary individually and also depend on the size of the treated area.

The laser has various modes, such as single, auto derm, and semi auto derm, allowing selection according to the target. This method approaches large areas more efficiently and small areas with precision.

• Precise irradiation for small, single lesions
• Uniform distribution for large areas
• Output adjustment according to the area and condition

Since UV exposure and aging are major factors in seborrheic keratosis, consistent application of sunscreen and lifestyle habits that reduce sun exposure are important. Even after management, it is advisable to ensure sun protection and moisturizing to prevent post-inflammatory hyperpigmentation.

The key to managing seborrheic keratosis is to create a treatment plan tailored to your skin condition, rather than trying to resolve it all at once. If it has been bothering you every time you look in the mirror, we recommend first identifying the type of lesion and then finding the method that suits you.
