Is there anyone who can summarize the features and advantages of lifting procedures?

I have mostly been managing my skin occasionally with minor injections, but I am planning to start proper treatments using laser or radiofrequency devices. Before visiting a clinic for a consultation, I would like to study the principles behind the popular devices preferred by users. I am posting this question because I want to clearly understand the specific features, advantages, and benefits of these lifting procedures compared to existing simple hydration or whitening programs. Is the advantage of inducing collagen regeneration by delivering thermal energy deep into the dermis or SMAS layer truly certain? I am also curious if the side effects, such as skin barrier irritation or scabbing caused by severe irritation, are relatively low. Since I work, I would be concerned if the procedure is too noticeable, so I want to check if it is a lifting treatment that allows for an immediate return to daily life. I look forward to honest feedback from experienced users who are knowledgeable about safe lifting procedures using genuine tips and whether the cumulative effects last a long time after a single treatment.
