I would like to inquire about the Livihill Skin Booster.

As winter approaches, my skin has lost elasticity and my overall tone has become dull. Perhaps it's because of the winter weather, but perhaps it's also because my skin looks dull and irritated due to the season, so I've been considering a skin booster treatment. My entire face, in particular, feels puffy and lacks moisture and radiance, so I feel like I need a fundamental skin improvement treatment.

I've been looking into the Livihill Skin Booster and it seems that the treatment options are Shining, Elastic, and Exosome. I'm curious about the differences between each and which type is especially recommended for winter skin.

Please tell me which of the three types above is the best choice for managing dull and sagging skin in winter, and what the recommended number of treatments/intervals and maintenance period are for each.
