Was very excited to trying this viral product, and it didn’t disappoint! You need very little of this product, one pump is enough for the whole face, and it spreads out nice and thin on the skin. You feel the pricking sensation right away, but it’s not so intense where you can’t stand the pain. It’s definitely good to start with the lower levels and work up to the higher ones to get used to the sensation. My skin is very sensitive and was worried about using this, but I had no reactions from it! In fact my skin was looking plump and glowy within the first few days of using it!
