I am a specialist in dermatology and venereology, and I gained my over 6 years of professional experience while working at the Department of Dermatology and Venereology, USK im. WAM in Łódź. At the OT.CO Clinic, I conduct treatments in the field of aesthetic, regenerative and anti-aging medicine. I specialize in non-surgical face lifting with the use of hyaluronic acid, treatments using botulinum toxin (reduction of mimic wrinkles, treatment of hyperhidrosis or bruxism) and laser therapy (photorejuvenation, resurfacing, scars, stretch marks, tattoo removal). In my daily practice, I also perform treatments aimed at preventing and treating hair loss. When working with a patient, I focus on detailed advice, the use of modern treatment methods and a friendly atmosphere during the visit.
