This serum reigns above every other Boots product in terms of reader curiosity due to reports this serum is comparable to tretinoin, the active ingredient in Retin-A and Renova. The research was carried out by scientists at the University of Manchester, with the conclusion that this Boots serum was just as effective at stimulating collagen production as tretinoin, yet costs considerably less. That sounds great until you learn that Boots paid for the research, which means they had a vested interest in making sure the study made their product look great. Also, because the study was done "blind" instead of double-blind, the researchers knew who was getting which treatment. This type of study isn't as reliable as double-blind studies because, especially when money is at stake, there is a natural bias toward making sure the product in question comes out in the best possible light.
"Our studies show" is a major attention-getting technique used in cosmetic advertising and press releases. Studies are great and vital to understanding how skin works and what helps skin work better, but not all studies are created equal and one study is not definitive of anything. Further, a study paid for by the company selling the product is ALWAYS circumspect. It's not that the study may not be valid, but the bias is present from the beginning and that must always be taken into consideration.
More to the point, any legitimate research would include the negative studies as well or compare other products from other lines. No one has even seen a cosmetic company tell you about the studies they did where the product tested didn't work or if other products from other companies worked as well. One more point: comparing a product to tretinoin in a short period of time is just absurd. Tretinoin works over time (there's abundant research about that), it initially makes the skin worse due to the irritation it can cause, such that over time there is no way to know what the results would have been.
Protect & Perfect Beauty Serum is silicone-based and contains a small amount of vitamin C as sodium ascorbyl phosphate (which research has shown is not as effective as ascorbic acid, though it is more stable). A nearly insignificant amount of vitamin A (as retinyl palmitate, not retinol as claimed) and other antioxidants hardly makes this an anti-aging product worth any amount of frenzy. Its vitamin C content and other attributes are not even worth mild enthusiasm when you consider that several companies offer serums that are infinitely more state-of-the-art. And if you're looking for peptides (or hope that the ones used in this Boots serum will spell certain doom for your wrinkles), this isn't the product that will flood your skin with them. In fact, there are more preservatives than peptides in this fragrance-free serum. Despite out dispelling the hype this product generated (and remember, it all began with funding from Boots, and no one else has reproduced the results from their "study"), it can be a good serum-type moisturizer for all skin types, and the silicones make skin feel wonderfully silky.
This product comes in translucent glass packaging that will compromise the stability of the vitamin C and vitamin A unless this is constantly kept away from light.
By the way, there is plenty of substantiated, published research indicating that topically applied vitamin C can stimulate collagen production, but so can a lot of other ingredients (for example any sunscreen comes to mind), but you would need more vitamin C than what is in this Boots serum.

Keep in mind that one skin care ingredient is never enough for skin just like one type of food (like broccoli) doesn't make for a healthy diet. It is the combination of healthy substances that is truly the best for skin, there isn't one miracle ingredient to be found anywhere.
And by the way, even Boots doesn't believe their own claims or they wouldn't be selling dozens of products making the same promises about getting rid of wrinkles. If the one they launched works what are all the others for?
