Is Density High okay for dry, dull skin in the fall?

I was very worried because my skin became tanned and dry from sweating so much all summer. Even though the weather has cooled down recently, I am concerned because my skin is severely dry from within and my complexion looks dull. Even after getting plenty of sleep, my skin feels rough and lacks elasticity, so I became curious if the Density High treatment would be helpful.

I have heard that Density High stimulates collagen deep within the skin to improve elasticity and hydration, so I would like to know the actual satisfaction level regarding the improvement of internal dryness. I am also curious about the average cost, treatment time, and recovery process, as well as the recommended number of sessions and the duration of the effects depending on skin condition.

I would like to hear opinions from those who have experienced it regarding whether Density High is suitable for restoring dry, dull skin during seasons like autumn when UV rays are significantly weaker.
