Dr Atessa Assim

Dr. med. Atessa Assim is a German board-certified consultant dermatologist who practises at Harley Street, London, and across the UK. With over 25 years of clinical experience spanning dermatology, dermatosurgery, allergology, venereology, and aesthetic dermatology, she offers a rare breadth of expertise.

She specialises in skin cancer surgery, venereal diseases (sexually transmitted infections), and cosmetic dermatology, with a focus on delivering results that are both medically precise and aesthetically refined. Her approach is underpinned by a unique foundation in anaesthesiology and intensive care medicine — an advantage that sets her apart from most dermatologists, ensuring exceptional standards of perioperative safety, pain management, and surgical planning.

Surgical and procedural expertise

Skin cancer excision (BCC, SCC, melanoma)

Local skin flap reconstruction

Skin grafting

Scar revision surgery

Advanced suturing techniques for optimal cosmetic closure (multi-layered sutures, tension-reducing methods, fine cosmetic sutures)

Mole removal with dermoscopic evaluation for early skin cancer detection

Her surgical work integrates oncologic precision, aesthetic consideration, and advanced pain management strategies, supported by her previous anaesthesia and intensive care training.

Allergy subspecialty training in dermatology (Germany)

After completing her board certification in dermatology, she pursued an additional two-year subspecialty training in Allergology (“Zusatzweiterbildung Allergologie”) in Germany. This advanced qualification focuses on the diagnosis and treatment of allergic conditions across the spectrum of Type I–IV hypersensitivity reactions. Her training included extensive experience with skin testing methods (prick, intradermal, and epicutaneous/patch testing), allergen-specific immunotherapy, oral and nasal provocation tests, and laboratory-based IgE diagnostics. She developed clinical expertise in managing conditions such as atopic dermatitis, allergic contact eczema, urticaria, anaphylaxis, and work-related allergies. The program also emphasized emergency care, preventive strategies, and patient education. The subspecialty training was completed under certified supervision and concluded with official certification.

Anaesthesiology and intensive care foundation

Before specialising in dermatology, Dr Assim completed over two years of clinical experience in anaesthesiology and intensive care medicine at Knappschaftskrankenhaus Püttlingen, Germany, where she independently performed spinal, epidural, and combined spinal-epidural (CSE) anaesthesia, delivered total intravenous anaesthesia (TIVA) and sedation, managed peripheral nerve blocks (brachial plexus, infraclavicular, axillary), placed central venous and arterial lines, led postoperative pain management, and handled anaesthetic emergencies with confidence. This background enhances her precision, safety, and patient-centred surgical care in dermatology.
