# Deep hydration facial at Seongnam skin clinic: Stern Clinic - By Damsol (https://superchart.com/en/@coffee-after-lunch/) - Written Sep 9, 2026 - Local places › Hair & beauty salons › Seongnam, Gyeonggi - Sponsored: This post was created with support from the business. - English edition: https://superchart.com/en/@coffee-after-lunch/sunae-deep-hydration-stern-clinic/ - Also in: [한국어](https://superchart.com/ko/@coffee-after-lunch/sunae-deep-hydration-stern-clinic/index.md) ## In short Stern Clinic is a cosmeceutical skin clinic near Sunae Station in Bundang, Seongnam, offering tailored care for troubled skin and barrier recovery. After detailed diagnostics, the writer received a 110-minute deep hydration treatment for facial flushing, inner tightness, and extreme dryness. Verdict: the delicate, moisture-focused treatment felt especially luxurious. ## Good to know - **Deep hydration treatment duration**: 110 minutes - **Hours**: Monday and Friday 12:00–21:00; Saturday 10:00–18:00 - **Closed**: Regularly closed Wednesday and Sunday - **Parking**: Available *as written by the visitor on Sep 9, 2026* I’ve been to hospitals and esthetics clinics for skincare, but I’d never seen facilities this grand before... It’s a somewhat specialized skincare clinic. Rather than simply offering treatments, Stern Clinic runs non-medication, non-procedure programs for troubled-skin regeneration, postoperative side-effect care, atopic and sensitive-skin care, and recovery of damaged skin barriers—a German cosmeceutical clinic. ![Stern Clinic skincare program guide](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-01-6pd5d-966.webp) There are personalized package programs. Most treatments take more than three hours including consultation, so if I can receive one at this price, I think it’s a huge win. ## Why I visited for facial flushing and inner tightness Facial flushing, inner tightness, extreme dryness. Do I need to say more? ## How the clinic approaches troubled skin > For skin exhausted or experiencing side effects from meridian massage, contouring treatments, plastic surgery, or excessive procedures It’s the age of self-care. Meridian massage, contouring treatments, plastic surgery, excessive procedures—and huh? Your skin should look younger, but instead it becomes thin and brittle. When personal home care offers no answer, this is a medical-integrated skin esthetics approach you can try to promote skin regeneration and the protective barrier. ![Skin regeneration and protective-barrier care guide](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-02-1eqc0-966.webp) ![Troubled-skin care guide](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-03-r3kz0-966.webp) ![Skin esthetics treatment guide](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-04-1l51i-966.webp) ![Skin protective-barrier care guide](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-05-uhh83-966.webp) One key feature is its use of German Dr. Stern products. ## Stern Clinic location and hours - Monday and Friday 12:00–21:00 - Saturday 10:00–18:00 - Regularly closed Wednesday and Sunday - Parking available ## Detailed skin consultation and tailored treatment plan ![Detailed skin consultation and tailored care guide](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-06-11vqi-966.webp) ![Consultation checking skin condition](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-07-1bt87-966.webp) Before my appointment, I submitted skin information through a Google Form, and then they checked my skin’s current condition in great detail using a consultation-only camera and questionnaire. Ah... the problems are visible even without magnifying it... I had clogged pores (from poor circulation), with inflammation around them causing redness. My pores are large, and my skin has very little oil—like a desert. It’s not troubled skin, but it is at a level that needs the approach used for troubled-skin care. We proceeded with a moisture-improvement program through deep hydration. ![Deep hydration moisture-improvement program](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-08-1a66w-966.webp) ![Deep hydration treatment in progress](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-09-17qgn-966.webp) When they observed my skin with the special camera in the treatment room... those red glowing spots were pores “stagnated” by blocked sebum, apparently. I use cleansing oil every day... (they say this isn’t good.) Even though I wash my face thoroughly, I guess there were still areas I was missing. ![Skin observation using a special camera](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-10-1xqdx-966.webp) ![Treatment device guide after skin observation](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-11-elx1g-966.webp) They said the treatment device was made in-house specifically for sensitive skin. ## The 110-minute deep hydration treatment process ![110-minute deep hydration treatment process](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-12-12mwv-966.webp) They apply gel to calm skin irritation, then you receive light therapy while soothing the skin. They keep spraying mist throughout, so your skin stays hydrated in a way that truly suits a treatment called deep hydration. The gauze pack, thoroughly soaked in Centella asiatica essence, provides a soothing effect. The touch during treatment was astonishingly delicate, like handling a bird. ![Centella asiatica essence gauze-pack treatment](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-13-10flg-960.webp) ![Skincare treatment with a delicate touch](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-14-ux7vv-679.webp) They use an ampoule tailored to extremely dry skin. The blue liquid becomes more pronounced once it is on the skin; an active solution similar to the body’s internal moisture is technically delivered into the skin through the device. ![Ampoule treatment tailored to extremely dry skin](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-15-1golt-966.webp) During the treatment, there is manual care for the chin and neck here and there. I was surprised by how luxurious this skincare treatment felt—it was such an indulgence. > The scientific approach to skin, the standard of products used, and the therapist’s kindness and quality of care They say even people with many skin concerns or symptoms of skin conditions are seeing improvement. Honestly, it seemed like there was hardly any reason to go elsewhere for regular skincare in Bundang. ## Self-care and guidance after treatment ![Self-care room after treatment](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-16-1mmvj-966.webp) ![Getting-ready space after skincare treatment](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-17-1f7wq-966.webp) Once the treatment is over, you get ready in the self-care room. Even the combs are wrapped in plastic—wow... the level of service was so high that I felt almost undeserving. ![Services provided after skincare treatment](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-18-ryud7-966.webp) Because this is a long-term cosmedical program, the cost may feel burdensome, but various discount promotions are underway. Even for a one-time treatment, they provide samples of the Dr. Stern products used in the care. After treatment, please minimize activities that may irritate the skin, such as going to a sauna. ![Guide to minimizing skin irritation after treatment](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-19-1mxya-966.webp) ![Post-treatment precautions for skincare](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-20-12hbf-966.webp) ![Stern Clinic treatment guide](https://img.superchart.com/images/sunae-deep-hydration-stern-clinic/sunae-deep-hydration-stern-clinic-21-1lacu-596.webp) ## Where it is - Stern Clinic (스테른클리닉) - 4F, Donghyeon Plaza Building, 11 Baekhyeon-ro 101beon-gil, Bundang-gu, Seongnam-si, Gyeonggi-do, South Korea (경기도 성남시 분당구 백현로101번길 11 동현프라자빌딩 4층) - 경기도 성남시 분당구 백현로101번길 11 동현프라자빌딩 4층 - 37.3770923, 127.1119747 - Google Maps: https://www.google.com/maps/search/%EC%8A%A4%ED%85%8C%EB%A5%B8%ED%81%B4%EB%A6%AC%EB%8B%89/@37.3770923,127.1119747,17z --- Superchart · https://superchart.com/en/@coffee-after-lunch/sunae-deep-hydration-stern-clinic/ · https://superchart.com/llms.txt
