I'm looking up reviews for Vitaran. What do you think?

Lately, my skin feels like it's cracking and drying out like it's been through a drought, and it's driving me crazy. ㅠㅠ The internal dryness is so severe that I feel like my elasticity has dropped drastically. When I apply makeup in the morning, it just sits on the surface, and by the afternoon, it's all settling into those fine lines. Tears...

I saw a review of Vitaran saying that it contains salmon extract but causes much less pain, and that really sounds tempting.

Is there anyone who can write a review for Vitaran? Does the skin texture become softer after just one session?

I work a full-time job and have to go to work the very next day. I've read reviews of Vitaran that say you can resume normal daily activities immediately, but others say it varies from person to person. If that is possible, it would be really great. What do you think?
