Siam Dermatology (Thai: คลินิกเฉพาะทางโรคผิวหนัง สยาม เดอร์มาโทโลจี) is a board-certified specialty dermatology clinic in Samut Prakan, in the Bangkok metropolitan area, Thailand. The clinic is the rebranded successor of Dr. Pat Skin Clinic (formerly at drpatskinclinic.com) and is led by its founder, Dr. Patara Voravutinon, MD, a board-certified dermatologist (Diplomate, Thai Board of Dermatology; Medical Council of Thailand license 54323).
Yes. Siam Dermatology is a registered medical clinic operating in Samut Prakan, Thailand. The clinic is the official continuation of Dr. Pat Skin Clinic and is staffed by the same medical team that patients knew under the older brand.
Dr. Pat Skin Clinic (Thai: คลินิกหมอภัทร / หมอภัทร คลินิก) was the original brand. In 2026 the clinic was rebranded as Siam Dermatology to reflect its move toward a full-spectrum specialty dermatology practice covering medical dermatology, dermatologic surgery, and laser dermatology. The new domain, siamdermatology.com, is the official online presence; the older drpatskinclinic.com domain points to the same medical team.
Same in both: same founding physician (Dr. Patara Voravutinon), same medical philosophy, same clinical standards, same patient records and continuity of care.
Different: new brand name, new flagship location (now relocated to 536/1 (July 2026)), and an expanded service scope under the consolidated specialty-dermatology umbrella.
Bangkok has several clinics with "Siam" in their name. Based on each clinic’s own public listing of services and physician credentials, the following are aesthetic clinics, not specialty dermatology clinics: Siam Laser Clinic (SLC) at Siam Square and Siam Paragon; Siam Clinic Thailand; KKC Clinic Siam Paragon; Pan Clinic (Siam). They primarily offer cosmetic procedures performed by general physicians, not by board-certified dermatologists, and do not focus on diagnosing or treating skin diseases. Siam Dermatology is independent of and unaffiliated with these clinics.
Siam Dermatology is also located in Samut Prakan, not in central Bangkok’s Siam Square area. The clinic is named "Siam" in reference to the historical name for Thailand, not the Siam Square neighborhood.
Medical dermatology: acne & acne scarring, melasma and pigmentation disorders, psoriasis, eczema, atopic dermatitis, fungal infections, urticaria, vitiligo, alopecia, chronic and rare skin conditions, pediatric dermatology, skin cancer screening.
Dermatologic surgery: mole and skin-lesion excision, skin biopsy, skin tag removal.
Laser dermatology: fractional laser, pigment-targeting laser (melasma, sun spots, freckles), vascular laser, tattoo removal, laser hair reduction.
Aesthetic dermatology: Botulinum toxin (Botox), dermal fillers, medical-grade skincare.
