I want to know if Rejuran is absolutely necessary just because my skin is dry.

Even when it is not winter, there are many days when my skin feels tight after washing my face.

It gets better for a while if I apply moisturizer, but
It feels dry again in the afternoon.

While looking into Rejuran
I saw that we need to distinguish between simple dehydration and a weakened skin barrier.

If you have sensitive skin that turns red easily
I am also wondering if it is necessary to check my current skin condition before choosing a procedure.

I want to know if I should be careful when choosing a skin booster based solely on dryness.
