After using this for 2 weeks, I have noticed a huge difference with how my skin looks. I struggle with acne and this has not made me breakout at all and if i get a pimple, it’s almost gone by the next day. I also love there is no fragrance as that is an irritant. Will definitely be buying this again!

Amazing ingredient Quality!

Size: 1 Ounce (Pack of 1)

Excellent! I am most in love with the actual texture..a little goes a very long way! It’s moisturizing is unbelievable and feels thick yet it’s almost a gel like feeling as it glides on and all over so well! Leave a glow and moments after you can def see firmness evolve. Mid day and morning after evening use , especially after this first week I can tell a difference long term in my jaw and neck as well as forehead and crowd feet!! Just purchased the peel shot bundle!! Xo

Scam!

Size: 1 Ounce (Pack of 1)

Do NOT buy. It doesn’t help the under eyes right away like it’s supposed to according to the video. I wish I realized sooner that it’s a scam and now I cannot return.
