(Question) How effective is the Ultracol Skin Booster?

I have sensitive skin, so I am quite hesitant about getting any treatments. My current concerns are improving my pores and skin elasticity. While looking into various skin boosters, I heard that Ultracol is effective. I would like to know if receiving the Ultracol skin booster actually improves pores and fine lines on sensitive skin, to what extent it improves elasticity, if there are any side effects, and if it is effective after just one session.
