The formula is really good quality and leaves my skin tight and glowy after use.

I’ve added this serum and bouncy mask from Drunk elephant to my skin care routine. I’m loving how my skin got more clear and glowy. Definitely will continue using them

The serum leaves my skin glowing. However, sometimes the serum is to heavy for my sensitive skin 

I love this serum because my skin turns perfect when I use  

In terms of efficacy, the serum is great, and has visibly reduced my acne scars. I have repurchased it 3x! However, the smell is very unpleasant (rancid egg), and the formula is relatively sticky. If you don't wait long enough before applying your next product, it will pill!
