It feels good so far but it’s too soon to say if it’s helped. Also, it has a lot of crystallization. I’ve shook a lot but it still has it.

I have tried almost every product/every brand..and SIV is my holy grail!!
I have never had a product make such a difference in my skin in a short period of time!
I was using the skinbetter line for my rosacea/antiaging with minimal results.
My redness kept getting worse and worse..a friend recommended SIV and im so grateful!!
You can’t go wrong with SIV.
