The suitability and effectiveness of non-surgical under-eye aesthetic procedures largely depend on factors such as the individual's facial structure, skin type, and expectations. Skin suitability is of critical importance. For instance, individuals with thick skin may not achieve the expected benefits from certain treatments, while procedures like laser on very thin skin can lead to undesirable reactions or sensitivity if not applied carefully. Therefore, a comprehensive skin assessment before each treatment is essential to determine the most appropriate method and to adjust application parameters specifically for the individual.
