Which laser treatment can effectively improve skin laxity?

Radiofrequency lasers are known for their ability to improve skin laxity by effectively heating the deeper layers of the skin, promoting collagen production and tightening the skin over time. This method works by delivering focused thermal energy to stimulate the fibroblasts, which are crucial for collagen synthesis. As collagen levels increase, the skin appears firmer and more youthful, addressing issues related to sagging and laxity.

In contrast, the other types of lasers mentioned do not specifically target skin laxity as effectively. Nd:YAG lasers are often used for vascular lesions and hair removal, while pulsed dye lasers are primarily used for conditions like rosacea or birthmarks. Molecular lasers are not a standard classification in aesthetics, making their efficacy in improving skin laxity unclear. Thus, radiofrequency lasers stand out for their direct impact on skin tightening, making them the preferred option for this concern.
