Glassy Skin Clinic, Seoul.

All medical treatments at Glassy Skin Clinic are performed by our board-certified dermatologists: Dr. Judy Hong Jin Joo, MD, our founder and medical director, Dr. Max, Dr. Sunny and Dr. Sophie. Your dermatologist does your consultation and your medical treatment, and all four consult and treat in English themselves. Skincare and LED treatments are performed by our skin therapists.

No, we don't use sedation. You stay awake so your dermatologist can check how you feel and adjust the treatment in real time. For comfort, we rely on our GLT™ technique and numbing cream; see comfort and pain control.

Yes. We apply numbing cream before almost all treatments, for example Sofwave, brightening lasers, laser hair removal, acne-scar treatments, CureJet, Potenza and wrinkle-relaxing injections. For lifting treatments such as PTing and Linear Z, we use it if you are sensitive to pain. In our clinic's experience, PTing usually causes little discomfort even without numbing cream, especially on the body. For under-eye fine lines treated with GLT™ Collagen Healer, numbing cream is essential, and we apply it for at least 30 minutes before treatment.

Downtime is usually short because of our GLT™ (Gentle Layered Treatment) technique, which spreads energy and product in thin layers across several skin depths instead of one intense pass. In our clinic's experience, most patients can wear makeup right after treatment and go back to work the same day, including after treatments with a cannula, such as under-eye Volume Lifting. In our clinic's experience, skin-layer treatments such as GLT™ Collagen Healer with Juvelook or Re2O don't cause swelling; the multi-needle injector may leave small red marks for 1–3 days (up to 1–7 days for sensitive skin). After GLT™ Collagen Volume Lifting with Juvelook Volume, swelling lasts 3–7 days on average and can last 10–14 days in some people, as part of the normal response while collagen builds. Bruising is uncommon, and if it happens, it usually clears within about 2 weeks. Recovery can vary with the treatment and your skin.

The day after every treatment, our team contacts every patient to ask about any discomfort (our “Happy Call”). If anything worries you, during your stay or after you fly home, you can send a photo of your skin via WhatsApp or Instagram, and we'll explain what you're seeing. In our experience, most patients feel reassured.

For patients who have had a treatment or skincare with us, we may recommend clinic-exclusive skincare and supplements matched to their skin type. We don't recommend them after a 3D Skin Analysis, consultation or doctor visit alone.

Yes. Your treatment takes place in a private room, not a shared treatment area. This lets your dermatologist focus on you and gives you privacy throughout the treatment.

Most visits take about 1–3 hours. The time depends on the treatment and whether you combine more than one treatment on the same day.
