"Design a polished and professional Meta ad image for a web developer offering custom website design services tailored for dermatologists in the USA. The background should feature a modern, serene dermatology clinic with minimalist, clean décor, hinting at skincare products or medical tools. In the foreground, display a sleek, well-designed website mockup on both a desktop computer and smartphone screen, emphasizing responsive design. Avoid showing faces on the screens; instead, focus on clear navigation elements, text, and icons related to skincare services, such as smooth skin textures and subtle cosmetic imagery. Use a calming color scheme of white, light green, and pastel tones to evoke cleanliness, trust, and calmness. Include a prominent call-to-action button that says 'Get Your Dermatology Website!' with a subheading like 'Attract More Patients with a Custom Design for Your Practice.' Keep the overall aesthetic clean, professional, and visually soothing."
