Firming serum after a workout...

Even though it is autumn, the daytime temperature is too high...

After my morning workout, I apply a firming serum for my skin, which has been tired all summer.

Hives broke out due to itching

I chose this because it has completed allergy and non-comedogenic tests.

* Hyaluronic acid, which is good for elasticity

They say that if the particles are large, it only provides temporary moisture to the skin surface.
