During summer, skin is more susceptible to irritation due to intense UV exposure, high temperatures, and frequent outdoor activities. In particular, after a summer vacation, some people may notice increased dryness, reduced skin elasticity, fine lines, or skin sagging. These changes may be associated with photoaging caused by prolonged exposure to UV rays. As skin elasticity can also decline during the summer, ultrasound-based lifting treatments may be considered alongside moisturizing-focused skincare as one approach to improving skin firmness.

Ultherapy is a type of ultrasound lifting treatment that delivers focused ultrasound (HIFU) energy to specific depths within the skin to stimulate collagen regeneration and improve skin elasticity. More recently, Ultherapy PRIME, an upgraded version of the existing system, has been introduced. It allows the skin layers to be viewed in real time through imaging, enabling more precise treatment based on the individual's skin condition.

One of the features of Ultherapy PRIME is that the depth and range of energy delivery can be adjusted according to the individual's skin thickness and degree of sagging. This is designed to reduce unnecessary energy delivery and allow treatment to be performed while taking discomfort into consideration. It may be used to improve skin laxity and elasticity in areas where sagging is more noticeable, such as the jawline and cheeks.

However, the treatment area and energy intensity can vary depending on the individual's skin condition and degree of aging. Therefore, it is important to establish a personalized treatment plan based on a thorough assessment.

Recently, many people researching Ultherapy and Ultherapy PRIME focus primarily on treatment costs or online reviews. However, rather than making a decision based solely on price, it is important to consider factors such as whether genuine equipment and genuine treatment tips are used, the practitioner's level of expertise, and whether the clinic can provide a one-on-one treatment plan that reflects the individual's skin condition. When choosing a clinic, it is also important to consider its diagnostic process and post-treatment care system.

Dr. Choi Seung-ho, a board-certified plastic surgeon at CHAI Plastic Surgery in Seoul, advised, “Lifting treatments are not simply about pulling the skin tighter. To improve satisfaction, the treatment should be performed after accurately analyzing each individual's skin condition and pattern of aging.”

He added, “Ultherapy PRIME also requires a personalized treatment plan that takes skin thickness and the degree of sagging into consideration. It is advisable to check whether genuine equipment is being used and consider the practitioner's clinical experience before deciding on treatment.”
