The packaging is really clean and the pump dispenser worked beautifully throughout the contents of the bottle. Thank you!”

Rating: 5/5 stars “I am typically skeptical of skin treatments outside of my normal routine. I tried Youth Infusion Serum based on a friend's recommendation and have been SO pleased. I noticed a difference in my skin after just a few applications. I've now recommended to quite a few family members and friends and they are hooked as well!”

Rating: 5/5 stars “I am quite conflicted on reviewing this product. I certainly noticed a smoother and suppler skin texture, which is great! However I found that using this daily lead to blemishes and increased sensitivity. I use a facial brush, and when using this product consistently, found that my skin would become irritated. At 27 this product may be too intensive for my needs.”
