Cellex-C Advanced C Serum is one of Cellex-C's best selling products with many loyal, long-term customers.   It's a 2-step system that many may find inconvenient.

Scientific-Backing of Ingredients  
The main active anti-aging ingredient are L-Ascorbic acid (vitamin C), glycerine, zinc and amino acid acetyl tyrosine, which have scientic research to back up its moisturizing anti aging properties.  It also includes grape skin and grape seed extracts which are strong anti-oxidants able to fight free radical damage to the skin.*

Lacking in Cellex-C are anti-aging and moisturizing ingredients such as multi-peptides, retinol palmitate, and niacinamide.

User Experience and Complaints
While clinical trials resulted in an impressive 84.2% reduction in wrinkles after 1 month, only 25-50% noticed other desired outcomes such as improved firmness, smoothness, and skin tone and reduced discoloration. 

In a survey of 31 users, only 25% would buy the product again.  The biggest challenge for users is using the 2-step system.   

There are no BBB complaints found against the company, Cellex-C International. 

Guarantee
Cellex-C  has a 30 day money back guarantee (less S&H) depending on which distributor you purchase it through. 

Price
Lowest price found at Amazon.com for the 2-step kit – $95.91.     

Conclusion
Cellex-C Advanced C Serum is a good product, although the application is not convenient and it does not work for everyone. Because there are other products with longer money back guarantees, and better results in areas that Cellex-C were weak (improving skin firmness, smoothness, tone), we recommend trying Cellex-C if other top rated products don't work for you.
