Severe internal dryness caused by indoor air conditioning, Rejuran Healer effects and duration of marks

Spending all day in the office exposed to air conditioning has left the surface of my skin shiny with sweat and oil, while the inside feels incredibly dry and tight, as if it is tearing apart. No matter how much moisturizer I apply, it just sits on the surface and makes the skin feel slippery without addressing the inner dryness at all. Therefore, I am considering getting the Rejuran Healer treatment, which directly replenishes moisture and nutrients to the dermis. I’ve heard that Rejuran is the best for treating inner dryness, so I’m curious if the effects are truly immediate. Also, since it is an injection procedure, I’ve heard that raised, embossed marks can appear on the face. I’m wondering if it usually takes a few days for these marks to completely subside so they remain unnoticeable during daily activities.
