Many people notice signs of aging when skin loses its elasticity and begins to sag around the face, jawline and neck. Intrinsic aging, also known as the natural aging process, is a continuous process that normally begins in our mid-20s (see graph below). Lifestyle, diet, personal habits and sun exposure often act together with the normal aging process to prematurely age our skin. Most premature aging is caused by sun exposure (photoaging). Other external factors that prematurely age our skin are repetitive facial expressions, gravity, sleeping positions, and smoking.
Real-time Temperature Feedback for Clinical Reproducibility: The Mechanism of Action of Profound Patients who are interested in facial rejuvenation are increasingly well informed, expecting visible and significant results after undergoing an aesthetic procedure. However, many energy based devices cannot guarantee clinical efficacy due to shortfalls in their engineering design and inherent lack of reproducibility. This paper aims to describe the underlying reasons behind the strikingly high response rate of a Profound procedure after a single treatment session.
